-The polarity detection of the three gap energy socket wiring
-The safety perform detection of the leakage swap
-It could shortly and precisely detect the wiring
hearth safety/laboratory/manufacturing facility/household
1. The traditional voltage vary of zero hearth line is plus or minus 10% of the native normal voltage. Whether it is too excessive or too low, it might be as a result of the circuit load is just too excessive or the facility provide is just too low/ too excessive.
2. The traditional voltage of zero-earth wire is lower than 2V, if too excessive possibly it’s as a result of there may be present leakage, or the three phase-sequence is out of steadiness or there may be sign interference within the circuit.
Please flip off all electrical home equipment earlier than utilizing this perform,and achieve this with permission to make sure that the facility outage is not going to trigger any hurt
