In Technical Round each and every subject you have touched upon. It was more of like a rapid fire where short and instant answer were required. Few questions that i can recall were; 1. 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.

If i decrease the operating pressure of a fractionating column, will the reboiler heat duty decrease?
