1. APPLICATION

The ND10 meter is a digital programmable panel meter destined for the measurement of the 3-phase, 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.

5.1. Current inputs

All current inputs are galvanically isolated (internal current transformers). The meter is suited to operate together with external measuring current transformers. Displayed values of currents as well as their derivative values are automatically calculated using set ratio value of the external transformer. Current inputs are specified in the order as either 1 A or 5 A.

5.2 Voltage inputs

Displayed values of voltages as well as their derivative values are automatically calculated using set ratio value of the external transformer. Voltage inputs are specified in the order as either

3 x 57,7/100 V, 3 x 230/400 V or 3 x 290/500 V.

example 1 of alarm setting:

Set n-on alarm type for monitored quantity P – 3-phase active power,

Version: 5 A; 3 x 230/400 V. Setting the alarm on after exceeding

3800 W, switching the alarm off after power drops to 3100 W.

Calculations: rated 3-phase active power: P = 3 x 230 V x 5 A

= 3450 W

3450 W – 100 %

3800 W – A1on %

3450 W – 100 %

3100 W – A1of %

In conclusion: A1on = 110,0 % A1of = 90,0 %

Set: Monitored quantity: P; type of alarm: n-on, A1on 110,0,

A1of 90,0.

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 MW.

Calculations:

ND10 meter active rated 3-phase power: P = 3 x k u

x u n

x k

I

x I n

= 3 x 1 x 230 V x 500 x 5A = 1,725 MW g 100 %.

Ordered-to-rated power ratio = 1 MW / 1.725 ≈ MW 57,97 % of meter rated value (rounded down) - Pord ;

Alarm operation hysteresis: alarm should be activated at 90 % ordered power ( A1on ), and deactivated for e.g.: at 1 % lower

89 % ( A1of ).

Optimization of power limit function (delay at alarm activation): alarm activation delay t o

= 60 s ( A1dt ).

1.5 MW

A1on=90.% A1of=89.9%

Time of delay A1dt= 0 sec fig. 9 shows an example of how the consumed ordered active power parameter can be used to alarm activation. Delay time is set at 0 seconds ( A1dt ).

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.

Fig. 9. Measurement of used ordered 15 minutes’ active

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.
