2.3 Connector System of Generator
Warnings
To prevent possible electrical shock, fire, or personal injury:
Do not touch any of the connections to the output terminals when any
voltage is present.
Do not make connections to the output terminals when any voltage is
present. These voltages can be lethal.
Current cables of generator (for max 120A) use plastic
“push – pull” connectors. With these connectors, user simply plugs them into terminals until a click sound is heard. It means that connector is locked.
While pulling out these connectors, they should be released first. This is achieved with pressing gently and then pulling it out completely. With such a gentle push unlocking of internal mechanism happens.
Figure 6
– Current cable connector on the front panel of PTE
Each current phase is equipped with one (mutual) output terminal (red) and two input (black) terminals.
The bigger one is designed for currents up to 120A, the smaller one is designed up to 12A but with different maximum power output for small currents (see pictures in next chapter).
Voltage and current connectors are compatible with standard laboratory banana types.
2.3.1 Power Characteristics of PTE (Generator)
Figure 7 - Bigger input terminal - Current Figure 8 - Smaller input terminal - Current
From these characteristics it is obvious that the high current
(“120A~ max”) input is used for direct meters which usually have lower resistivity on current terminals. On the other hand low current (
“12A max.”) input is dedicated for indirect meters which usually come with higher resistivity on current terminals.

2.6 Description of features
Portable Test Equipment consists of two devices: source of measuring signal and
Working Standard.
The source is accurate multifunctional and powerful signal generator. Working Standard is an accurate three phase reference meter of electrical quantities. The whole device is dedicated for calibration of electricity meters, and eventually can be used as supply of measuring signals or as reference meter of voltage, current, power and energy.
The device is designed to work in single-phase, two-phase and three-phase connections where signals can be generated with different shapes for various values of parameters and simultaneously measure all characteristic variables including curves and real time values of percentage errors of calibrated meter.
User can set characteristics of generated signals in a simple user interface of generator mode and in measuring mode measurement results are displayed in real time. The results are stored in an internal database, from where, using the USB bus, can be transferred into the PC. Measurement and evaluation values are implemented in all phases separately and also cumulative.
Measuring section either displays characteristics of generated signal or allows via versatile interchangeable inputs connection of different external meter accessories: current transducer for small currents up to 20 A, current clamps for currents up to 120 A or 240 A, flexible current probe for high currents up to 6000 A or voltage transducer for voltages up to 500 V (phase to neutral).
Measurement based on accurate A/D conversion and DSP technology enables high-speed evaluation of all main and descriptive variables in real time. In addition to measuring power, voltage, current and phase device also indicates the phase sequence, evaluates active, reactive and apparent energy. The apparatus measures and graphically displays distortion and shape of measured signals. For calibration purpose the device is equipped with frequency output, for which any variable and frequency constant can be set.
The appliance is equipped with integrated error processing capability, with optical sensor for capturing
LED, disk or impulse contacts of verified meters and snap switch for simple manual verification.
The device is powered externally from 230V. Software for MS Windows allows transmission and presentation of measurement data in PC.

2.7 Generator
Warnings
To prevent electric shock or personal injury, remove all cables from the terminals that are not used. When connections are made to a circuit that can be energized with voltages, always ensure there are no external voltages present before connecting to the Product. Voltage can be present at the loose ends of cables.
Caution
To prevent damage to the Product, do not connect mains power to any signal input or output terminal.
The basic function of the device is generating signals. The periodic sine wave is used as standard signal. Generating of Burst Fired and Phase Fired which are defined by the norm is also comprised in default configuration. In addition to these three options, the user can define own harmonic composition of signal with individual setting of amplitudes and phases of separate harmonic content of signals.
Generator section in the SW uses green headers.
Starting of signal generation is achieved by red button which is located in the left bottom corner of the keypad. Start and stop mode is always active, regardless of the currently displayed screen. If generating is active, there is small colored square indication, which is located in the right top corner of the display next to the clock. Orange square is briefly displayed at the beginning and end of each generated signal and represents rise time and fall time of signal. If the square is filled with red color stable generation is in progress. Alternative indication of generation is also a beep (but it has to be enabled in generator settings).
To switch between screens of generator and meter serves the green button located in the right bottom corner of the keypad.
Generator remains active even if there is some screen of measuring section currently displayed.
Or vice versa, i.e. measurement remains active even if the user switches to the generator section.

When all necessary parameters are set, it is possible to initiate signal generation with a start button . The same key serves for termination. When changing any parameter it is highlighted in red.
These changes are not stored in memory. They are saved only when the generation starts, and then the red color of changed data turns black.
For start generating, from any screen, always last saved values are used. The same applies after power on.
In case that is needed to change other parameters of generation, which are not included in the Basic screen of generator, it is possible to use the function keys:
F1 ........... it starts and ceases signal generation
F3 ........... it opens a menu of available signals
– screen “Signal Shapes”
F4 ........... it opens a menu of automatic run of predefined tests
– screen “DB Measurements”
F5 ........... it allows changing the settings of generator section
Exp ................. it opens Power Factor screen
3.2.1 Error in generation
When error in generation occurs, device automatically skips to Standby in corresponding channel.
Standby means that generation in particular channel is suspended. Once the error cause has been removed, generation update is possible, usually with F2 button. However if voltage error occurs, it is necessary to stop and run again the generation.
Typical situation: current loop has been malfunctioned so the generation in respective channel is suspended. Error (red notification in main generator screen) in given channel occurs, i.e. no current generation in that phase, however voltage remains untouched. After current loop examination and reparation, the generation shall be restored by F2.
Conclusion: Meter remains under power (voltage) through the whole time.

5.2.2 Dial Test
This page can be accessed from Load Values screen by F3.
Configuration of Dial tests is in Test Settings menu, where mode (Time or Energy), amount of time / energy and energy type (Active, Reactive, Apparent) is specified.
When Generator (PTE) has dosage feature enabled (see chapter 4.3.1 Generator Settings) Dial test
automatically controls also start and stop of power generation. When dosage is active (energy is being accumulated with realtime generation) red highlighted “Dosage” message flashes on each screen.
Test is started with F1 key. After first press initialization occurs and dial test is prepared. At this stage
#1 field (see picture below) should be filled with initial state of register of electricity meter.
After second press of F1 key testing begins. If the Generator section is enabled for Dosage, generation of current and voltage starts automatically.
After third press of F1 key the testing is aborted by user. If the Generator section is enabled for Dosage and
“Stop voltage” (and /or current) is also enabled Generator will also cease generating this quantity
(U and /or I). After that user can fill #2 field (see picture below). Then Error is calculated.
If the user will not interrupt the testing by third press of F1 key PTE will terminate testing automatically after reaching certain value of energy or time (depends on Test settings).
Note:
Before first initialization (right after Dial test screen is opened) it is recommended to generate voltage
(only) to have such meter under power. This is useful especially for static/electronic meters so user is capable of performing initial register reading. When Dosage starts (second F1 press) PTE automatically generates U and I.
COUNTERS Section:
This section is related to the values obtained from meter. Meter connected to the network can measure quantities via transformer. In such case meter’s parameters can be defined for transformer’s secondary side (Sec.) or calculated to the primary side (Prim.).
Operator enters initial state of meter counter #1 before test and final state of meter counter #2 after test. Device automatically calculates difference (
ΔE) and evaluates test error. It is also possible to define directly the difference (
ΔE).
Energy measurement Section:
This section is related to the energy measurement obtained by device. CT (Current) and VT (Voltage) ratios are acquired from database. In this window they can be changed (they turn red). By default both
Prim. / Sec. switches are set to the same value which is associated to database item.
These switches along with CT / VT ratios enable to set where the meter is placed (during measurement) and where the device measures energy.
Running in Automatic Mode (chapter 4.2.3 on page 27) uses also this mode, which means that during
dial test in Automatic Mode (defined on green screen) actually this Dial test runs in the background on the blue screen and also all fields are filled. In such scenario fields #1 and #2 are filled automatically (if optical communication head with static meter is used) or manually
– user must switch into this screen and fill #1 at the beginning and #2 at the end of dial test.
Dial Test runs always simultaneously with Maximum Demand Test which has to last longer than Dial
Test. The reason lies in principle of Dial Test evaluation. This feature offers also evaluation of these two tests concurrently.

Remark:
Energy (Dial) test can lose accuracy when inappropriate amount of energy over time is intended to dose. Error for the result of dial test can be expressed as (for PTE):
100. 𝑈 𝑚𝑎𝑥
. 𝐼 𝑚𝑎𝑥
𝑈. 𝐼. 74000. 𝑡𝑖𝑚𝑒
Then, for instance with range of accessory 500V/120A and dosing only 0.1A (230V) for 60s, it causes an error of 0.059%. With higher current or with more time the error directly proportionally decreases.
This behavior is caused by lower resolution for small currents disregarding other errors like device accuracy.
Conclusion: Dose more power for longer time (several minutes)!

’s register before and after MD test. This operation will ease the whole test procedure.
During MD test the icon above F1 depicts the sign of play. In this state the test can be prematurely stopped by F1 and the icon changes to stop sign. To evaluate the MD test, it is compulsory to wait until the test stops automatically or at least wait until the time “End” passes because only then the “MD Reg.” will obtain value different from zero. This is the value which is compared with the meter’s MD register.
When the test is ceased, “Enter MD register” message flashes until any key is pressed. This warning informs the operator to submit the value of MD register from meter. Then the overall MD error is calculated.
Dial Test runs always simultaneously with Maximum Demand Test which has to last longer than Dial
Test. The reason lies in principle of Dial Test evaluation. This feature offers also evaluation of these two tests concurrently.
Meter connected to the network can measure quantities via transformer. In such case meter’s parameters can be defined for transformer’s secondary side or calculated to the primary side (upper switch
– Sec / Prim). By default, both Prim. / Sec. switches and CT/VT ratios are acquired from database. They can be changed (they turn red). These switches along with CT / VT ratios enable to set where the meter is placed (during measurement) and where the device measures energy.

Constant type ................ Primary / Secondary
– for indirect meters in the database, indicates which side of the connection view to transformer is referred the constant of electricity meter. For direct meters the default value is always Secondary and in that mode this parameter is not displayed. With parameter change the constant is automatically converted under CT VT transformation ratios stored in database for actual meter.
With changing the parameters CT Ratio, VT Ratio and Constant type the Constant parameter is automatically recalculated in the Meter Error Test screen and used in subsequent tests. When user changes the Constant type back to the value according to database item associated to that meter,
Constant value is set to default for this meter type. It means CT and VT ratio parameter values are ignored in Meter Error Test screen. If CT or VT has been changed, Constant type value has to be toggled to opposite (against database) to reflect the Constant value modification.
In a case, that this mode is activated from Database, then the Parameters are set according to the selected meter. If this mode is activated from Load Values screen the Parameters are set according to the Measurement Settings.
Navigation between parameters can be done by
▼▲ arrows, parameter selection can be done by OK key and changing of parameter’s value can be done by ◄ ► arrows. If any parameter has been changed, an asterisk sign (*) will be added to SN. It means that default values have been modified.
These parameters remain modified and marked with * until next enter to Database screen. Entering the
Database will set default parameters of corresponding meter.
F4 key which is available after performing meter error test saves test result (including load point info, signal shapes and harmonics) into results database for currently selected meter.
When Registration mode parameter is switched to “Snap. S” then F2 key turns into snap switch mode
(substitution of HW Snap Switch) and pulses can be registered with this F2 button.

Meter testing can be started or stopped by key F1. Voltage and current sensors have to be connected to tested meter and optical sensor has to be adjusted to meters emitting LED or disc or impulse SO cable has to be connected to device before start of testing.
Time between two samples (Integration time) and number of measured samples can be set in Test
Settings. Integration time is described in appendix, chapter Measurement Time. On principle: longer
integration time and higher number of measured samples brings measured results with higher accuracy and stability.
First mark is ignored after start of testing and after each following mark device shows actual value of measured error and increments counter of measured samples.
Average Error and Standard Deviation are evaluated after measuring required number of samples.

5.4 Transformer Test
Test of current transformers (CT) or voltage transformers (VT) can be done after connecting of suitable combination of current and voltage measuring sensors.
Testing of single phase transformer can be done using one three phase measuring accessory which is connected to transformer this way: L1 channel of accessory to secondary side and L2 (or L3) channel to primary side. Measurement screen shows result for both variants (L2/L1 and L3/L1).
Testing of three phase transformer (or also single phase transformer) can be done using two three phase current sensors (in case of current transformer testing) resp. two three phase voltage sensors
(in case of voltage transformer testing). Channels of sensor connected into input A has to be connected to secondary side of transformer and channels of sensor connected into input B has to be connected to primary side of transformer.
It is possible to use any combination of current measuring accessories (CT 2x20, CC 2x12, CC 2x24,
FCP 3xxx) for Current Transformer testing.
Measurement screens depend on combination of connected sensors and show: nominal and measured Transmission Ratio, Transmission Error and measured Phase Error.

7.5 Maintenance
The PTE is cooled by variable-speed fans. To get the most reliable performance, ensure proper air flow for the Product.
Caution
To guarantee correct operation of the PTE:
Do not block the vent openings located at the front panel.
Do not operate the Product in a dusty environment.
Inspect and clean all vent openings at least once a month.
Do not let liquids enter the Product through the vent openings.
Do not use the Product outside its operational temperature range.
Ensure that all cables are in good condition.
Use special (included) plugs that make a firm, secure connection to the
Product’s output binding posts. This is especially true for the current terminals, which can output 120 A and cause self-heating with loose fitting plugs.
Inspect the output binding posts prior to use. Repair loose output binding
posts before use.
Do not overload the output by leaving the Product switched on with the load
connected for a long time, especially on 120 A current range and 300 V voltage range.
If instruments to be calibrated are not connected to the Product output
terminals with the original test cables, ensure that cables suitable for the calibration adjustment voltage and current are used. Maximum output voltage can reach 300 V ac and the maximum output current can reach
120 A ac.
Do not use the smaller black output current terminals for currents greater
than 12 A. They are intended for indirect meters only
7.5.1 Regular Maintenance
The PTE does not require special maintenance of electrical or mechanical parts. Inspect the output binding posts for wear and any loose connections. The case and the display can be cleaned by a microfiber cloth rag moistened with alcohol.
The PTE should be verified at the recommended two years interval.
7.5.2 Clean the Product
Caution
To prevent damage to the PTE, do not use aromatic hydrocarbons or chlorinated solvents for cleaning. They can damage the materials used in the
PTE.
For general cleaning, first disconnect all power input and signal cables. Wipe the PTE with a soft cloth dampened with water or a non-abrasive mild cleaning solution that does not harm plastics.
