1 APPLICATION
The ND10 meter is a digital programmable panel meter destined for the measurement of the 3phase, 4-wire power network parameters in balanced and unbalanced systems. It is also capable of displaying measured quantities and their simultaneous digital transmission. The meter is also capable of controlling and optimization of the power electronic devices, systems, and industrial installations.
The meter can be used for measuring: RMS value of voltage and current; active, reactive and apparent power; active and reactive energy, power parameters; frequency, 15-, 30- and 60-minute mean active power and THD. Additionally, a current in the neutral wire is calculated from the phase current vectors .
Voltage and current values are multiplied by given voltage and current ratios of measuring transformers.
Power and energy indications take into account all programmed ratio values. Any and all measured values can be sent to the master via the RS-485 interface. The relay outputs signal alarm when selected parameters exceed set limits. Impulse output can be used for consumption check of the 3-phase real energy. This meter is also able to detect and signal incorrect phase sequence.
The meter is powered by the measuring circuit, i.e. from the voltage output.
There is a galvanic separation between following units of the meter:
- voltage and current inputs,
- RS-485 output,
- impulse output.

3-phase separate measurements are made for 15-second quantum. Depending on chosen value (15 min, 30 min, 60 min) calculated mean value is based on 60, 120 or 240 measurements. After the meter is turned on or after the power is reset, the first value will be calculated in 15 seconds after turning meter on or resetting. Until all probed values of the active power are acquired, mean power value is calculated from values already measured. Current in the neutral wire I
(N) is calculated from phase current vectors.
When alarms are activated, symbols A1 and/or A2 are displayed. When alarms are deactivated and alarm signalization latch is turned on, flashing symbols A1 and/or A2 are displayed.

Example no 2 of alarm setting:
The value of ordered power consumption may be used for the purpose of prior warning that ordered power might be exceeded. Ordered power consumption is calculated according to time period set for the mean active power synchronization and value of the ordered power. Pre-emptive alarm should be set so that it indicates the possibility of exceeding ordered power of 1MW at 90 % assuming allocation of 15-minutes
(900 s). Measuring current transformer 2500: 5A, voltage 230 V. Peak max power consumption 1,5

In presented example for the remaining 10 % of ordered power at maximum power consumption, all devices could operate for additional 60 seconds without imposing penalties. If the delay time A1dt had been set to 60 seconds, alarm would not have been activated.
A1on = 90.0 %
A1of = 89.9 %
Time of delay A1dt = 0 sec
Ordered power
Fig. 10. Measurement of used ordered 15 minutes’ active power consumption synchronized with the clock, with alarm set on a 90% consumption.
Set alarm as following: monitored quantity: A1_n = P_ord; alarm type: A1_t = n-on; A1on = 90,0,
AL1oF = 89,9; delay time A1dt = 0 or 60 s; A1_s = 0; A1_b = 0. Parameters should be set as following: tr_I = 500; Syn = 15 or c_15, and Pord = 57.9.

7 Software upgrade
ND10 meter (with digital output) allows for firmware upgrade via PC with LPCon software installed.
LPCon software is available as freeware on the www.lumel.com.pl
web site. Upgrade is possible if PC is connected to RS485 to USB converter, such as PD10 converter. a) b)
Fig. 11. Program window view: a) LPCon, b) software upgrades
Important! Software upgrade automatically reverts meter to its default (factory) settings, so it is recommended to save meter settings with LPCon software before upgrading.
After launching LPCon program, set in Options required serial port, speed, mode and address of the meter. Next, choose ND10 meter from Devices menu and click the Read icon to read all set parameters (required for later recovery). After choosing Device software upgrade option from
Upgrade menu a Lumel Updater window appears(LU) – Fig. 11 b. Press Connect. The Messages information window displays information concerning upgrade process. If the port is opened correctly, a Port opened message appears. Upgrade mode may be entered using either of the two methods: remotely via LU (using LPCon settings: address, mode, speed, COM port) or by switching on a meter with a button pressed (while entering bootloader mode, upgrade button is used to set default communication settings of the meter). Meter display shows the "boot" message and the software version while the LU program displays Device found message along the name and version of the software of connected device. Click the ... button and browse to the meter upgrade file. If the file is opened correctly, a File opened message is displayed. Press the Send button. When upgrade is successfully completed, meter reverts to the default settings and begins normal operation while the information window displays Done message and upgrade elapsed time. After the LU window is closed, click the Save icon to save all initially read parameters. Current software version can be checked by reading Device information from LPCon software.

Energy is made available in hundreds of watt-hours (var-hours) in double 16-bit register, and for this reason, one must divide them by 10 when calculating values of particular energy from registers, e.g.:
Consumed active energy = (reg. value 4038 x 65536 + reg. value 4039) / 10 [kWh]
Released active energy = (reg. value 4040 x 65536 + reg. value 4041) / 10 [kWh]
Reactive inductive energy = (reg. value 4042 x 65536 + reg. value 4043) / 10 [kVarh]
Reactive capacity energy = (reg. value 4044 x 65536 + reg, value 4045) / 10 [kVarh]
