Comparing Classic EI, EE, C foil inductors, Flat wire toroidal inductors are hot in the market, here let’s discuss why people prefer flat wire, rather than common toroidal wire: Round Wire Limitations Frequencies >20KHz Round wire take best efficiency in frequencies up to 20KHz. In higher frequencies, skin effect (with electrons travelling mainly on the surface area of the conductor instead of ...

Fault earthing, also known as ground fault, is the accidental connection of the conductor to the earth. AGroundFaultCircuitInterrupter (GFCI) is a new type of circuit breaker that can prevent damage to house wiring and protect people from electric shock. The GFCI constantly monitors the current on the neutral and live wires in the circuit. When all is well, the current should be exactly the same o...
