Lightning, Surge Protection and Earthing of Electrical ... of the major effects of lightning strike on electrical and electronic equipment is a high voltage surge. A surge is caused by the lightning discharge when the associated current tries to find a path to ground. A surge need not be due to a direct strike alone but can happen due to a strike on a nearby structure.
Current Transformer - an overview | ScienceDirect Topics an AC motor drive using this technique we therefore have a means of judging the motor current. In a DC drive this circuit is also applicable since the AC supply (L 1, L 2, L 3) to the controlled rectifier is also a measure of the motor current on the output of the converter.The current transformers also implement galvanic separation between power and control circuit.
