(2) Content of pseudo-output

QE82LG

1) Using the intelligent function switch sett ings, you can start the test mode to output the fixed value.

2) For procedure for setting the intelligent function switch, refer to 7.5.2.

3) To finish the tes t mode, the set value is returned by th e intelli gent funct ion switch setting, and after that, it starts a measuring m ode (low sensitivity mode or high sensitivity mode) by resetting it. (It resumes with the previous set value and accumulated electric energy as well as periodic electric energy.)

For the value to be out put to the buff er memory, refer to Tables 6.1-1 to 6.1-3 in 6.1 Buffer memory assignment.

(3) Percolations for using the test function

- ZCT (CZ, ZT series) do not have a secondary output polarity .

- ZCT(CZ, ZT series) are dedicated for low voltage circuits. It cannot be used for high voltage circuits. Connecting

to a high voltage circuit by mistake can cause burning of equ ip ment and fir e, which is extremely dangerous.

- In the absence of voltage input, correct measurement cannot be performed, so be sure to connect the voltage input terminal.

- Two circuits can be measured by one module at sa me lin e an d same pha se wire system. (ex. It cannot be measured when CH1: three-phase 3-wire, CH2: single-phas e 3-wire)

- Measuring of the leakage current for resistance can be measured with single-phase 2-wire, single-phase 3-wire, three-phase 3-wire delta circuit.

- Measuring of the leakage current (Io) can be measured with three-phase 3-wire star circuit and special grounding circuit such as high resistance grounding circuit and capacitor gr ounding circuit..

A leak current is measured from the area exceeding 1 mA. In an area lower than 1 mA, a measurement result is indicated as “0” (zero).

Measurement of leak current (Io) is impossible without applying a voltage. When an input voltage is lower is 0 mA.

9.3 Q&A

9.3.1 General

T o what degree is the module durable against overvoltage and overcurrent? Is external protective circuit required?

Continuous : Up to 1.1 times as high as rated voltage and rated current.

* Momentary means: Energizing 9 times for 0.5 seconds at 1-minute intervals, and then 1 time for 5

seconds.

Is it OK to open secondary output terminal of zero-phase current transformer (ZCT)?

Do not open the secondary output terminals (k, l) of ZCT. Opening the secondary output ter mina ls may affect characteristics of ZCT. In addition, do not short-circuit or ground the test terminals (kt, lt) of ZCT. Otherwise, the leak current may not be detected correctly.

Is measurement of inverter circuit possible?

Make measurement on the primary side of the inverter. However, since a current waveform on the primary

Obtained values may be different from other measuring instruments. Why is it so?

[1] Check for wiring errors (connections of voltage circuits, in particular). [2] Check for the short-circuit on the secondary side of ZCT. [3] ZCT connectable to the module is the ded ica ted ZCT manufactured by Mitsubishi Electric only. Check

that the proper ZCT is connected.

[4] On the split-type ZCT, check for the poor engagement or se p arati on of fittin g surf ac es. [5] On the split-type ZCT, check for the pinching of foreign object between fitting surfaces. [6] Check that the measuring instrument used for comparison indicates the correct RMS value. [7] If the measuring instrument used for comparison measures an average value instead of rms value,

distortion in the current of the circuit to be measured causes a significant dif f eren ce of valu es. This

9.3.2 Q&A about Specifications

What does “the module tolerance” against?

It means tolerance agai nst the inpu t leak curre nt. In case of low sensitivity mode, both of the leak current (Io) and resistance leak current (Ior) have a rated leak current of 1000 mA. Therefore, within the range of the input leak current from 100 to 1000 mA, a

tolerance is ±2.5% of input leak current. On the other hand, within the range of the input leak current below 100 mA, a tolerance is ±2.5 mA. In case of high sensitivity mode, a tolerance is ±2.5 mA because leak current rating is 100mA.

Is tolerance of zero-phase current transformer (ZCT) included?

Tolerance of the module does not include a tolerance of zero-phase current transformer (ZCT).

A maximum value of tolerance is obtained by summing tolerance of the module and that of zero-phase current transformer (ZCT).
