Chapter 1: Three-Phase Power

Measurement

Three-Phase Power Measurement

This introduction to three-phase power and power measurement is intended to provide only a brief overview of the subject. The professional meter engineer or meter technician should refer to more advanced documents such as the EEI Handbook for Electricity

Metering and the application standards for more in-depth and technical coverage of the subject.

1.1

Three-Phase System Configurations

Three-phase power is most commonly used in situations where large amounts of power will be used because it is a more effective way to transmit the power and because it provides a smoother delivery of power to the end load. There are two commonly used connections for three-phase power, a wye connection or a delta connection. Each connection has several different manifestations in actual use.

When attempting to determine the type of connection in use, it is a good practice to follow the circuit back to the transformer that is serving the circuit. It is often not possible to conclusively determine the correct circuit connection simply by counting the wires in the service or checking voltages. Checking the transformer connection will provide conclusive evidence of the circuit connection and the relationships between the phase voltages and ground.

1.1.1

Wye Connection

The wye connection is so called because when you look at the phase relationships and the winding relationships between the phases it looks like a wye (Y). Fig. 1.1 depicts the winding relationships for a wye-connected service. In a wye service the neutral (or center point of

EPM6100 MULTI-FUNCTION POWER METERING SYSTEM – USER GUIDE 1–1

THREE-PHASE SYSTEM CONFIGURATIONSCHAPTER 1: THREE-PHASE POWER MEASUREMENT the wye) is typically grounded. This leads to common voltages of 208/120 and 480/277

(where the first number represents the phase-to-phase voltage and the second number represents the phase-to-ground voltage).

The three voltages are separated by 120° electrically. Under balanced load conditions the currents are also separated by 120°. However, unbalanced loads and other conditions can cause the currents to depart from the ideal 120° separation.

Three-phase voltages and currents are usually represented with a phasor diagram. A phasor diagram for the typical connected voltages and currents is shown in Figure 1.2

The phasor diagram shows the 120

° angular separation between the phase voltages. The phase-tophase voltage in a balanced three-phase wye system is 1.732 times the phase-toneutral voltage. The center point of the wye is tied together and is typically grounded.

Table 1.1 shows the common voltages used in the United States for wye-connected systems.

Usually a wye-connected service will have four wires; three wires for the phases and one for the neutral. The three-phase wires connect to the three phases (as shown in Fig. 1.1).

The neutral wire is typically tied to the ground or center point of the wye (refer to Figure

1.1).

In many industrial applications the facility will be fed with a four-wire wye service but only three wires will be run to individual loads. The load is then often referred to as a deltaconnected load but the service to the facility is still a wye service; it contains four wires if you trace the circuit back to its source (usually a transformer). In this type of connection the phase to ground voltage will be the phase-to-ground voltage indicated in Table 1.1, even though a neutral or ground wire is not physically present at the load. The transformer is the best place to determine the circuit connection type because this is a location where the voltage reference to ground can be conclusively identified.

1.1.2

Delta Connection

Delta connected services may be fed with either three wires or four wires. In a three-phase delta service the load windings are connected from phase-to-phase rather than from phase-to-ground.

Figure 1.3 shows the physical load connections for a delta service.

THREE-PHASE SYSTEM CONFIGURATIONSCHAPTER 1: THREE-PHASE POWER MEASUREMENT

In this example of a delta service, three wires will transmit the power to the load. In a true delta service, the phase-to-ground voltage will usually not be balanced because the ground is not at the center of the delta.

Fig. 1.4 shows the phasor relationships between voltage and current on a three-phase delta circuit.

In many delta services, one corner of the delta is grounded. This means the phase to ground voltage will be zero for one phase and will be full phase-to-phase voltage for the other two phases. This is done for protective purposes.

Another common delta connection is the four-wire, grounded delta used for lighting loads.

In this connection the center point of one winding is grounded. On a 120/240 volt, fourwire, grounded delta service the phase-to-ground voltage would be 120 volts on two phases and 208 volts on the third phase. Figure 1.5 shows the phasor diagram for the voltages in a three-phase, four-wire delta system.

Blondell’s Theorem and Three Phase Measurement

In 1893 an engineer and mathematician named Andre E. Blondell set forth the first scientific basis for poly phase metering. His theorem states:

• If energy is supplied to any system of conductors through N wires, the total power in the system is given by the algebraic sum of the readings of N wattmeters so arranged that each of the N wires contains one current coil, the corresponding potential coil being connected between that wire and some common point. If this common point is on one of the N wires, the measurement may be made by the use of N-1 wattmeters.

The theorem may be stated more simply, in modern language:

• In a system of N conductors, N-1 meter elements will measure the power or energy taken provided that all the potential coils have a common tie to the conductor in which there is no current coil.

• Three-phase power measurement is accomplished by measuring the three individual phases and adding them together to obtain the total three phase value.

In older analog meters, this measurement was accomplished using up to three separate elements. Each element combined the single-phase voltage and current to produce a torque on the meter disk. All three elements were arranged around the disk so that the disk was subjected to the combined torque of the three elements.

• As a result the disk would turn at a higher speed and register power supplied by each of the three wires.

• According to Blondell's Theorem, it was possible to reduce the number of elements under certain conditions. For example, a three-phase, three-wire delta system could be correctly measured with two elements (two potential coils and two current coils) if the potential coils were connected between the three phases with one phase in common.

EPM6100 MULTI-FUNCTION POWER METERING SYSTEM – USER GUIDE 1–5

1–6

THREE-PHASE SYSTEM CONFIGURATIONSCHAPTER 1: THREE-PHASE POWER MEASUREMENT

• In a three-phase, four-wire wye system it is necessary to use three elements. Three voltage coils are connected between the three phases and the common neutral conductor. A current coil is required in each of the three phases.

• In modern digital meters, Blondell's Theorem is still applied to obtain proper metering. The difference in modern meters is that the digital meter measures each phase voltage and current and calculates the single-phase power for each phase.

The meter then sums the three phase powers to a single three-phase reading.

Some digital meters calculate the individual phase power values one phase at a time. This means the meter samples the voltage and current on one phase and calculates a power value. Then it samples the second phase and calculates the power for the second phase.

Finally, it samples the third phase and calculates that phase power. After sampling all three phases, the meter combines the three readings to create the equivalent three-phase power value. Using mathematical averaging techniques, this method can derive a quite accurate measurement of three-phase power.

More advanced meters actually sample all three phases of voltage and current simultaneously and calculate the individual phase and three-phase power values. The advantage of simultaneous sampling is the reduction of error introduced due to the difference in time when the samples were taken.

FIGURE 1–6: Three-Phase Wye Load illustrating Kirchhoff’s Law and Blondell’s Theorem

Blondell's Theorem is a derivation that results from Kirchhoff's Law. Kirchhoff's Law states that the sum of the currents into a node is zero. Another way of stating the same thing is that the current into a node (connection point) must equal the current out of the node. The law can be applied to measuring three-phase loads. Figure 1.6 shows a typical connection of a three-phase load applied to a threephase, four-wire service. Krichhoff's Laws hold that the sum of currents A, B, C and N must equal zero or that the sum of currents into Node "n" must equal zero.

EPM6100 MULTI-FUNCTION POWER METERING SYSTEM – USER GUIDE

CHAPTER 1: THREE-PHASE POWER MEASUREMENTTHREE-PHASE SYSTEM CONFIGURATIONS

If we measure the currents in wires A, B and C, we then know the current in wire N by

Kirchhoff's Law and it is not necessary to measure it. This fact leads us to the conclusion of

Blondell's Theorem that we only need to measure the power in three of the four wires if they are connected by a common node. In the circuit of Figure 1.6 we must measure the power flow in three wires. This will require three voltage coils and three current coils (a three element meter). Similar figures and conclusions could be reached for other circuit configurations involving delta-connected loads.

EPM6100 MULTI-FUNCTION POWER METERING SYSTEM – USER GUIDE 1–7

POWER, ENERGY AND DEMANDCHAPTER 1: THREE-PHASE POWER MEASUREMENT

1.2

Power, Energy and Demand

It is quite common to exchange power, energy and demand without differentiating between the three. Because this practice can lead to confusion, the differences between these three measurements will be discussed.

Power is an instantaneous reading. The power reading provided by a meter is the present flow of watts. Power is measured immediately just like current. In many digital meters, the power value is actually measured and calculated over a one second interval because it takes some amount of time to calculate the RMS values of voltage and current. But this time interval is kept small to preserve the instantaneous nature of power.

Energy is always based on some time increment; it is the integration of power over a defined time increment. Energy is an important value because almost all electric bills are based, in part, on the amount of energy used.

Typically, electrical energy is measured in units of kilowatt-hours (kWh). A kilowatt-hour represents a constant load of one thousand watts (one kilowatt) for one hour. Stated another way, if the power delivered (instantaneous watts) is measured as 1,000 watts and the load was served for a one hour time interval then the load would have absorbed one kilowatt-hour of energy. A different load may have a constant power requirement of 4,000 watts. If the load were served for one hour it would absorb four kWh. If the load were served for 15 minutes it would absorb ¼ of that total or one kWh.

Figure 1.7 shows a graph of power and the resulting energy that would be transmitted as a result of the illustrated power values. For this illustration, it is assumed that the power level is held constant for each minute when a measurement is taken. Each bar in the graph will represent the power load for the one-minute increment of time. In real life the power value moves almost constantly.

The data from Figure 1.7 is reproduced in Table 2 to illustrate the calculation of energy.

Since the time increment of the measurement is one minute and since we specified that the load is constant over that minute, we can convert the power reading to an equivalent consumed energy reading by multiplying the power reading times 1/60 (converting the time base from minutes to hours).

Time Interval

(Minute)

Power (kW) Energy (kWh) Accumulated

Energy (kWh)

As in Table 1.2, the accumulated energy for the power load profile of Figure 1.7 is 14.92 kWh.

Demand is also a time-based value. The demand is the average rate of energy use over time. The actual label for demand is kilowatt-hours/hour but this is normally reduced to kilowatts. This makes it easy to confuse demand with power. But demand is not an instantaneous value. To calculate demand it is necessary to accumulate the energy readings (as illustrated in Figure 1.7) and adjust the energy reading to an hourly value that constitutes the demand.

In the example, the accumulated energy is 14.92 kWh. But this measurement was made over a 15-minute interval. To convert the reading to a demand value, it must be normalized to a 60-minute interval. If the pattern were repeated for an additional three 15minute intervals the total energy would be four times the measured value or 59.68 kWh.

The same process is applied to calculate the 15-minute demand value. The demand value associated with the example load is 59.68 kWh/hr or 59.68 kWd. Note that the peak instantaneous value of power is 80 kW, significantly more than the demand value.

Figure 1.8 shows another example of energy and demand. In this case, each bar represents the energy consumed in a 15-minute interval. The energy use in each interval typically falls between 50 and 70 kWh. However, during two intervals the energy rises sharply and peaks at 100 kWh in interval number 7. This peak of usage will result in setting a high demand reading. For each interval shown the demand value would be four times the indicated energy reading. So interval 1 would have an associated demand of 240 kWh/

EPM6100 MULTI-FUNCTION POWER METERING SYSTEM – USER GUIDE 1–9

POWER, ENERGY AND DEMANDCHAPTER 1: THREE-PHASE POWER MEASUREMENT hr. Interval 7 will have a demand value of 400 kWh/hr. In the data shown, this is the peak demand value and would be the number that would set the demand charge on the utility bill.

CHAPTER 1: THREE-PHASE POWER MEASUREMENTREACTIVE ENERGY AND POWER FACTOR

1.3

Reactive Energy and Power Factor

The real power and energy measurements discussed in the previous section relate to the quantities that are most used in electrical systems. But it is often not sufficient to only measure real power and energy. Reactive power is a critical component of the total power picture because almost all real-life applications have an impact on reactive power.

Reactive power and power factor concepts relate to both load and generation applications. However, this discussion will be limited to analysis of reactive power and power factor as they relate to loads. To simplify the discussion, generation will not be considered.

Real power (and energy) is the component of power that is the combination of the voltage and the value of corresponding current that is directly in phase with the voltage. However, in actual practice the total current is almost never in phase with the voltage. Since the current is not in phase with the voltage, it is necessary to consider both the inphase component and the component that is at quadrature (angularly rotated 90° or perpendicular) to the voltage. Figure 1.9 shows a single-phase voltage and current and breaks the current into its in-phase and quadrature components.

FIGURE 1–9: Voltage and complex current

The voltage (V) and the total current (I) can be combined to calculate the apparent power or VA. The voltage and the in-phase current (IR) are combined to produce the real power or watts. The voltage and the quadrature current (IX) are combined to calculate the reactive power.

The quadrature current may be lagging the voltage (as shown in Figure 1.9) or it may lead the voltage. When the quadrature current lags the voltage the load is requiring both real power (watts) and reactive power (VARs). When the quadrature current leads the voltage the load is requiring real power (watts) but is delivering reactive power (VARs) back into the system; that is VARs are flowing in the opposite direction of the real power flow.

Reactive power (VARs) is required in all power systems. Any equipment that uses magnetization to operate requires VARs. Usually the magnitude of VARs is relatively low compared to the real power quantities. Utilities have an interest in maintaining VAR requirements at the customer to a low value in order to maximize the return on plant invested to deliver energy. When lines are carrying VARs, they cannot carry as many watts.

So keeping the VAR content low allows a line to carry its full capacity of watts. In order to encourage customers to keep VAR requirements low, some utilities impose a penalty if the

VAR content of the load rises above a specified value.

A common method of measuring reactive power requirements is power factor. Power factor can be defined in two different ways. The more common method of calculating power factor is the ratio of the real power to the apparent power. This relationship is expressed in the following formula:

Total PF = real power / apparent power = watts/VA

EPM6100 MULTI-FUNCTION POWER METERING SYSTEM – USER GUIDE 1–11

REACTIVE ENERGY AND POWER FACTORCHAPTER 1: THREE-PHASE POWER MEASUREMENT

This formula calculates a power factor quantity known as Total Power Factor. It is called

Total PF because it is based on the ratios of the power delivered. The delivered power quantities will include the impacts of any existing harmonic content. If the voltage or current includes high levels of harmonic distortion the power values will be affected. By calculating power factor from the power values, the power factor will include the impact of harmonic distortion. In many cases this is the preferred method of calculation because the entire impact of the actual voltage and current are included.

A second type of power factor is Displacement Power Factor. Displacement PF is based on the angular relationship between the voltage and current. Displacement power factor does not consider the magnitudes of voltage, current or power. It is solely based on the phase angle differences. As a result, it does not include the impact of harmonic distortion.

Displacement power factor is calculated using the following equation:

Displacement PF = cos Θwhere Θis the angle between the voltage and the current (see

Fig. 1.9).

In applications where the voltage and current are not distorted, the Total Power Factor will equal the Displacement Power Factor. But if harmonic distortion is present, the two power factors will not be equal.

CHAPTER 1: THREE-PHASE POWER MEASUREMENTHARMONIC DISTORTION

1.4

Harmonic Distortion

Harmonic distortion is primarily the result of high concentrations of non-linear loads.

Devices such as computer power supplies, variable speed drives and fluorescent light ballasts make current demands that do not match the sinusoidal waveform of AC electricity. As a result, the current waveform feeding these loads is periodic but not sinusoidal. Figure 1.10 shows a normal, sinusoidal current waveform. This example has no distortion.

The distortion observed in Figure 1.11 can be modeled as the sum of several sinusoidal waveforms of frequencies that are multiples of the fundamental 60 Hz frequency. This modeling is performed by mathematically disassembling the distorted waveform into a collection of higher frequency waveforms. These higher frequency waveforms are referred to as harmonics. Figure 1.12 shows the content of the harmonic frequencies that make up the distortion portion of the waveform in Figure 1.11.

FIGURE 1–12: Waveforms of the harmonics

The waveforms shown in Figure 1.12 are not smoothed but do provide an indication of the impact of combining multiple harmonic frequencies together.

When harmonics are present it is important to remember that these quantities are operating at higher frequencies. Therefore, they do not always respond in the same manner as 60 Hz values.

Inductive and capacitive impedance are present in all power systems. We are accustomed to thinking about these impedances as they perform at 60 Hz. However, these impedances are subject to frequency variation.

At 60 Hz,

= 377; but at 300 Hz (5 th harmonic)

ω

= 1,885. As frequency changes impedance changes and system impedance characteristics that are normal at 60 Hz may behave entirely different in presence of higher order harmonic waveforms.

Traditionally, the most common harmonics have been the low order, odd frequencies, such as the 3 rd

, 5 th

, 7 th

, and 9 th

. However newer, non-linear loads are introducing significant quantities of higher order harmonics.

Since much voltage monitoring and almost all current monitoring is performed using instrument transformers, the higher order harmonics are often not visible. Instrument transformers are designed to pass 60 Hz quantities with high accuracy. These devices, when designed for accuracy at low frequency, do not pass high frequencies with high accuracy; at frequencies above about 1200 Hz they pass almost no information. So when instrument transformers are used, they effectively filter out higher frequency harmonic distortion making it impossible to see.

CHAPTER 1: THREE-PHASE POWER MEASUREMENTHARMONIC DISTORTION

However, when monitors can be connected directly to the measured circuit (such as direct connection to 480 volt bus) the user may often see higher order harmonic distortion. An important rule in any harmonics study is to evaluate the type of equipment and connections before drawing a conclusion. Not being able to see harmonic distortion is not the same as not having harmonic distortion.

It is common in advanced meters to perform a function commonly referred to as waveform capture. Waveform capture is the ability of a meter to capture a present picture of the voltage or current waveform for viewing and harmonic analysis. Typically a waveform capture will be one or two cycles in duration and can be viewed as the actual waveform, as a spectral view of the harmonic content, or a tabular view showing the magnitude and phase shift of each harmonic value. Data collected with waveform capture is typically not saved to memory. Waveform capture is a real-time data collection event.

Waveform capture should not be confused with waveform recording that is used to record multiple cycles of all voltage and current waveforms in response to a transient condition.

POWER QUALITYCHAPTER 1: THREE-PHASE POWER MEASUREMENT

1.5

Power Quality

Power quality can mean several different things. The terms ‘power quality’ and ‘power quality problem’ have been applied to all types of conditions. A simple definition of ‘power quality problem’ is any voltage, current or frequency deviation that results in mis-operation or failure of customer equipment or systems. The causes of power quality problems vary widely and may originate in the customer equipment, in an adjacent customer facility or with the utility.

In his book “Power Quality Primer”, Barry Kennedy provided information on different types of power quality problems. Some of that information is summarized in Table 1.3 below.

It is often assumed that power quality problems originate with the utility. While it is true that may power quality problems can originate with the utility system, many problems originate with customer equipment. Customer-caused problems may manifest themselves inside the customer location or they may be transported by the utility system to another adjacent customer. Often, equipment that is sensitive to power quality problems may in fact also be the cause of the problem.

If a power quality problem is suspected, it is generally wise to consult a power quality professional for assistance in defining the cause and possible solutions to the problem.

Utility Peak Demand

The EPM6100 Meter provides user-configured Block (Fixed) Window or Rolling Window

Demand. This feature allows you to set up a Customized Demand Profile. Block Window

Demand is demand used over a user-configured demand period (usually 5, 15 or 30 minutes). Rolling Window Demand is a fixed window demand that moves for a userspecified subinterval period.

For example, a 15-minute Demand using 3 subintervals and providing a new demand reading every 5 minutes, based on the last 15 minutes.

Utility Demand Features can be used to calculate kW, kVAR, kVA and PF readings. All other parameters offer Max and Min capability over the user-selectable averaging period.

Voltage provides an Instantaneous Max and Min reading which displays the highest surge and lowest sag seen by the meter

Considerations When Installing Meters

Installation of the EPM6100 Meter must be performed by only qualified personnel who follow standard safety precautions during all procedures. Those personnel should have appropriate training and experience with high voltage devices.

Appropriate safety gloves, safety glasses and protective clothing are recommended.

During normal operation of the EPM6100 Meter, dangerous voltages flow through many parts of the meter, including: Terminals and any connected CTs (Current Transformers) and

PTs (Potential Transformers), all I/O Modules (Inputs and Outputs) and their circuits. All

Primary and Secondary circuits can, at times, produce lethal voltages and currents. Avoid contact with any current-carrying surfaces.

Do not use the meter or any I/O Output Device for primary protection or in an energylimiting capacity. The meter can only be used as secondary protection. Do not use the meter for applications where failure of the meter may cause harm or death.

Do not use the meter for any application where there may be a risk of fire.

All meter terminals should be inaccessible after installation.

Do not apply more than the maximum voltage the meter or any attached device can withstand. Refer to meter and/or device labels and to the Specifications for all devices before applying voltages. Do not HIPOT/Dielectric test any Outputs, Inputs or

Communications terminals.

GE recommends the use of Shorting Blocks and Fuses for voltage leads and power supply to prevent hazardous voltage conditions or damage to CTs, if the meter needs to be removed from service. CT grounding is optional.

• IF THE EQUIPMENT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, THE

PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.

• THERE IS NO REQUIRED PREVENTIVE MAINTENANCE OR INSPECTION NECESSARY FOR

SAFETY. HOWEVER, ANY REPAIR OR MAINTENANCE SHOULD BE PERFORMED BY THE

FACTORY.

Introduction

The EPM6100 Meter has an option for a Wi-Fi (Wireless) or RJ-45 Ethernet connection. This option allows the submeter to be set up for use in a LAN (Local Area Network), using standard Wi-Fi base stations. Configuration for these connections is easily accomplished through your PC using Telnet connections. Then you can access the submeter to perform meter functions directly through any computer on your LAN: the EPM6100 meter does not need to be directly connected (wired) to these computers for it to be accessed.

This chapter outlines the procedures you use to set up the EPM6100 Meter to function via its Ethernet configuration.

These instructions are for EPM6100 Meters that have a Reset button, located on the

main board.

You can easily tell whether or not your meter has a Reset button: open the front cover of the EPM6100 Meter. The Reset button is located at the top, right of the main board. Refer to the figure below.

Some earlier versions of the EPM6100 Meter are not equipped with a Reset button. The instructions for Ethernet configuration are slightly different for these meters.

If your meter does not have a Reset button, please call GE’s Technical Support department

(at 905-294-6222) to obtain configuration instructions for your meter’s Ethernet connection.

Configure Network Module

These procedures detail how to set up the EPM6100 Meter on the Network Module.

Only one person at a time can be logged into the network port. This eliminates the possibility of several people trying to configure the Ethernet interface simultaneously.

6.3.1

Configuration Requirements

You may want to consult your network administrator before performing these procedures.

Some functions may be restricted to the network administrator.

If you have only one Ethernet adapter (network card), the screen displays only that configuration. You will use this Ethernet adapter to access the EPM6100 Meter’s Network

Module. You may have to configure the Ethernet adapter in order to use it with the

EPM6100 Meter’s Network Module, using the instructions in Section 6.4.2.

If you have multiple Ethernet adapters (network cards) installed on your computer, you must choose, configure and use the correct one to access the Network Module.

The Ethernet Adapter must be set up for point-to-point connection in order for it to connect to the EPM6100 Meter’s Network module, as follows:

IP Address should be 10.0.0.2

Subnet Mask should be 255.255.255.0

These settings can be made in the Ethernet Adapter. Follow the procedure in Section 6.3.2.

CHAPTER 7: USING THE SUBMETERWATT-HOUR ACCURACY TESTING (VERIFICATION)

7.3

Watt-Hour Accuracy Testing (Verification)

The EPM6100 Meter has a Watt-Hour Test Pulse on the face of the submeter. This is an infrared pulse that can be read easily to test for accuracy.

To be certified for revenue metering, power providers and utility companies have to verify that this billing energy submeter will perform to the stated accuracy. To confirm the submeter’s performance and calibration, power providers use field test standards to ensure that the unit’s energy measurements are correct. Since the EPM6100 Meter is a traceable revenue submeter, it contains a utility grade test pulse that can be used to gate an accuracy standard. This is an essential feature required of all billing grade meters and submeters.

Refer to the figure below for an example of how this process works.

Formula Explanation

C4E11DB9 (hex) 11000100 11100001 00011101 10111001 (binary)

The sign of the mantissa (and therefore the number) is 1, which represents a negative value.

The Exponent is 10001001 (binary) or 137 decimal.

The Exponent is a value in excess 127. So, the Exponent value is 10.

The Mantissa is 11000010001110110111001 binary.

With the implied leading 1, the Mantissa is (1).C23B72 (hex).

The Floating Point Representation is therefore -1.75871956 times 2 to the 10.

Decimal equivalent: -1800.929

Exponent = the whole number before the decimal point.

Mantissa = the positive fraction after the decimal point.

Notes

1 All registers not explicitly listed in the table read as 0. Writes to these registers will be accepted but won't actually change the register (since it doesn't exist).

2 Meter Data Section items read as 0 until first readings are available or if the meter is not in operating mode. Writes to these registers will be accepted but won't actually change the register.

3 Register valid only in programmable settings update mode. In other modes these registers read as 0 and return an illegal data address exception if a write is attempted.

4 Meter command registers always read as 0. They may be written only when the meter is in a suitable mode. The registers return an illegal data address exception if a write is attempted in an incorrect mode.

5 If the password is incorrect, a valid response is returned but the command is not executed. Use 5555 for the password if passwords are disabled in the programmable settings.

6 M denotes a 1,000,000 multiplier.

7 Not applicable to EPM6000, THD (Software) Option 0

8 Writing this register causes data to be saved permanently in EEPROM. If there is an error while saving, a slave device failure exception is returned and programmable settings mode automatically terminates via reset.

9 Reset commands make no sense if the meter state is LIMP. An illegal function exception will be returned.

10 Energy registers should be reset after a format change.

11 Entities to be monitored against limits are identified by Modbus address. Entities occupying multiple Modbus registers, such as floating point values, are identified by the lower register address. If any of the 8 limits is unused, set its identifier to zero. If the indicated Modbus register is not used or is a nonsensical entity for limits, it will behave as an unused limit.

12 There are 2 setpoints per limit, one above and one below the expected range of values. LM1 is the "too high" limit, LM2 is "too low"

The entity goes "out of limit" on LM1 when its value is greater than the setpoint. It remains "out of limit" until the value drops below the in threshold. LM2 works similarly, in the opposite direction. If limits in only one direction are of interest, set the in threshold on the "wrong" side of the setpoint. Limits are specified as % of full scale, where full scale is automatically set appropriately for the entity being monitored: curren FS = CT numerator * t CT multiplier voltag FS = PT numerator * e PT multiplier

14 All 3 voltage angles are measured for Wye and Delta hookups. For 2.5 Element, Vac is measured and Vab & Vbc are calculated. If a voltage phase is missing, the two voltage angles in which it participates are set to zero. A and C phase current angles are measured for all hookups. B phase current angle is measured for Wye and is zero for other hookups. If a voltage phase is missing, its current angle is zero.

15 If any register in the programmable settings section is set to a value other than the acceptable value then the meter will stay in LIMP mode. Please read the comments section or the range for each register in programmable settings section for acceptable.

16 If the THD (Software) Option is THD and protocol (ppp) is set to 3 (DNP) then meter will use the MODBUS RTU protocol as DNP is supported by THD (Software) Option THD.

DNP 3.0 Protocol Assignments for EPM6100 Meter

D.1 DNP Implementation

Physical Layer

The EPM6100 Meter is capable of using RS485 as the physical layer. This is accomplished by connecting a PC to the EPM6100 Meter with the RS485 connection on the face of the submeter.

RS485

RS485 provides multi-drop network communication capabilities. Multiple submeters may be placed on the same bus, allowing for a Master device to communicate with any of the other devices.

Appropriate network configuration and termination should be evaluated for each installation to insure optimal performance.

Communication Parameters

EPM6100 Meters communicate in DNP 3.0 using the following communication settings:

• 8 Data Bits

• No Parity

• 1 Stop Bit

Baud Rates

EPM6100 Meters are programmable to use several standard baud rates, including:

• 9600 Baud

• 19200 Baud

• 38400 Baud

• 57600 Baud

DATA LINK LAYERCHAPTER D: DNP 3.0 PROTOCOL ASSIGNMENTS FOR EPM6100 METER

D.2 Data Link Layer

The Data Link Layer as implemented on EPM6100 submeters is subject to the following considerations:

Control Field

The Control Byte contains several bits and a Function Code. Specific notes follow.

Control Bits

Communication directed to the submeter should be Primary Master messages (DIR =

1, PRM = 1).

Response will be primary Non-Master messages (DIR = 0, PRM = 1). Acknowledgment will be Secondary Non-Master messages (DIR = 0, PRM = 0).

Function Codes

EPM6100 Meters support all of the Function Codes for DNP 3.0. Specific notes follow.

Reset of Data Link (Function 0)

Before confirmed communication with a master device, the Data Link Layer must be reset. This is necessary after a submeter has been restarted, either by applying power to the submeter or reprogramming the submeter. The submeter must receive a RESET command before confirmed communication may take place. Unconfirmed communication is always possible and does not require a RESET.

User Data (Function 3)

After receiving a request for USER DATA, the submeter will generate a Data Link

CONFIRMATION, signaling the reception of that request, before the actual request is processed. If a response is required, it will also be sent as UNCONFIRMED USER DATA.

Unconfirmed User Data (Function 4)

After receiving a request for UNCONFIRMED USER DATA, if a response is required, it will be sent as UNCONFIRMED USER DATA.

Address

DNP 3.0 allows for addresses from 0 - 65534 (0x0000 - 0xFFFE) for individual device identification, with the address 65535 (0xFFFF) defined as an all stations address.

EPM6100 submeters' addresses are programmable from 0 - 247 (0x0000 - 0x00F7) and will recognize address 65535 (0xFFFF) as the all stations address.

D.4.1.1 Binary Output Status (Obj. 10, Var. 2)

Binary Output Status supports the following functions:

Read (Function 1)

A READ request for Variation 0 will be responded to with Variation 2.

Binary Output Status is used to communicate the following data measured by EPM6100 submeters:

Energy Reset State

Change to MODBUS RTU Protocol State

Energy Reset State (Point 0)

EPM6100 Meters accumulate power generated or consumed over time as Hour

Readings, which measure positive VA Hours and positive and negative W Hours and

VAR Hours. These readings may be reset using a Control Relay Output Block object

(Obj. 12). This Binary Output Status point reports whether the Energy Readings are in the process of being reset, or if they are accumulating. Normally, readings are being accumulated and the state of this point is read as '0'. If the readings are in the process of being reset, the state of this point is read as '1'.

Change to Modbus RTU Protocol State (Point 1)

EPM6100 Meters are capable of changing from DNP Protocol to Modbus RTU Protocol.

This enables the user to update the Device Profile of the submeter. This does not change the Protocol setting. A submeter reset brings you back to DNP. Status reading of "1" equals Open, or de-energized. A reading of "0" equals Closed, or energized.
