how can we save enegry by using VFD for Resiprocating Air compressor which is having more unloading running hours
What is the implications when 600 hp motor is started when the unit is running with Transformer of capacity 1500 KVA and DG set of 1000kva
two way ckt diagram can be drawn by how many ways? give diagram
i need of the bhel question papers along with answers and also give some website names for the downloading question (electrical and electronics engg question)please help me....
what are the maximum available current, voltage ratings and switching speeds of the power electronic devices thyristor, power mosfet, igbt, and mct?
why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
