How to use the socket tester to judge the good grounding effect of the ground wire at home
Good grounding means that its grounding resistance must be smaller than the relevant national norms, and, in fact, the grounding resistance cannot be constant forever, nor can it be grounded reliably forever, so the relevant norms also state that it must be measured every year, but, In the home power distribution, the property rarely does this. It will be very troublesome to do the measurement at home. If the measurement is really done, it is found that the grounding resistance is too large, and it will be more troublesome to rectify. The method with strong operability is: in the socket circuit of your own, in addition to the ground wire, you must also connect the leakage protection circuit breaker, and use double protection to ensure the safety of electricity use. On this basis, you can buy a socket tester with leakage protection test online (note: there are many choices, the price is not expensive), follow the relevant instructions to simulate the leakage of electricity, and then you can judge whether the ground wire at home can play the corresponding role. Protective effects.
