Voltage measurement

1. The identical previous voltage fluctuate of zero fireplace line is plus or minus 10% of the native frequent voltage. Whether or not or not or not or not it is too excessive or too low, it is likely to be on account of the circuit load is just too excessive or the flexibility current is just too low/ too excessive.

2. The identical previous voltage of zero-earth wire is lower than 2V, if too excessive probably it’s on account of there could also be moreover present leakage, or the three phase-sequence is out of steadiness or there could also be moreover sign interference all by the circuit.

RCD TEST

Please flip off all electrical residence gear sooner than utilizing this perform,and buy this with permission to make it doable for the flexibility outage is simply not going to set off any harm

VA coloration current present

The high-definition current can see the present price clearly at midnight setting
