Although the diagram above represents anideal transformer, it is impractical because only a small portion of the flux from the first coil links with the second coil in open air. So the current that flows through the closed circuit connected to the secondary winding will be extremely small (and...
In this post I have explained a circuit which can be used for monitoring or controlling AC 220V load current by sensing the load current through a contactless current transformer. Figure 1 below depicts a circuit diagram designed for anon contact load currentsensing through a current transformer, ...
Test the SPD. Check whether the cables to the Annual primary and secondary loops are secured. Drive test for the low-voltage cabinet. Once every three years Maintain the internal dynamic contact of the circuit breaker, and perform a preventive test on the ...
