Poor electrical contact and multiple grounding are some of the more common phenomena in people's actual lives,Relay Tester mainly caused by the failure of voltage transformers;Relay Tester generally speaking, voltage transformers are an important component of the entire power system One of the parts is that it needs to work continuously in the daily operation of the system. Therefore,Relay Tester if a failure occurs,Relay Tester it will have a serious impact on the subsequent system operation and at the same time lay hidden dangers to its safety.

The failure of the voltage transformer is generally caused by improper design and management. For example,Relay Tester in the maintenance work, the inspection of the work is not carried out in place, so that the mechanical problem is not resolved,Relay Tester which in turn causes the machine to short-circuit during operation, and the voltage of the parts continues to increase ,Relay Tester Resulting in a reduction in the circuit load, resulting in an increase in current and short-circuit; In addition,Relay Tester poor contact of the secondary center point of the voltage transformer, multiple grounding will also make the voltage too large,Relay Tester when the secondary grounding,Relay Tester the voltage will be all Switching to the voltage of the device will in turn cause the relay protection measures to perform wrong actions.
