Circuit dismantling is another effective treatment for faults in relay protection devices.Relay Tester It is an important method to identify difficult circuits. Its working principle is mainly divided into two aspects. First, in series circuits,Relay Tester each is used There is a mutual influence between electrical appliances,Relay Tester and after any one of the electrical appliances is arbitrarily removed,Relay Tester there is no current in the other electrical appliances and the operation is stopped; second,Relay Tester in the parallel circuit, each electrical appliance is independent Work, there is no direct relationship between each other,Relay Tester so the arbitrary removal of any one or several electrical appliances will not affect other electrical appliances; therefore, Relay Tester for this feature, its measures can not only act as a protection method, but also act as Find method.

The parameter comparison method is mainly to solve the problem of abnormal relay value problems found in the relay protection device. Its working principle is mainly based on: Relay Tester each relay value has its own fixed index standard under normal conditions, and once it appears When abnormal, its value will change, Relay Tester so that the difference between the test value and the fixed value will continue to expand, Relay Tester so by comparing the relevant parameters of the fault relay with the normal relay, you can effectively find the fault relay,Relay Tester and then as follows One-step troubleshooting provides solid and reliable information.
