Resistance Temperature Detector (RTD): Resistance Temperature Detector (RTD) commonly use platinum, nickel or any resistance wire whose resistance varies with temperature and which has a high intrinsic accuracy. They are…
Chopper Resistance in the Rotor Circuit: Speed control by means of slip variation can be achieved by employing a variable resistance Chopper Resistance in the Rotor Circuit. From the equations…
Chopper Controlled Resistance: By interrupting the flow of current through a resistance R in a periodic fashion using a switch, the value of resistance can be effectively varied. The interrupÂtion…
What is a Temperature Transducer?: Temperature Transducer is one of the most widely measured and controlled variable in industry, as a lot of products during manufacturing requires controlled temperature at…
Stator Overheating Protection: Stator Overheating Protection - Generally stator overheating is caused by sustained overloads or by cooling system failure. Overheating because of short-circuited laminations is very localized, and it…
