Lenz Law, Faraday's law. 2. Transformer Impedance, Protection Scheme, Relays used. 3. Motor Working principle, Protection Scheme, Generator parallel Operation, Faults etc. 4. Types of relays and CB, working principle and Operating times, applications, insulators, cables types etc. 5. Relays, operating times, CT, PT, Wattmeter, Ammeter, voltmeter, energy meter. 6. Diode, rectifier, clipper, clamper, buck, boost, inverter, converters etc.
