Electrical Engineering - RTD And electrical heater


Expert: cleggsan - 12/26/2006

Question
Dear all

How are the RTDs connected to the winding let say a motor. Is it hook up like the current transformer?

Answer
Temperature dependent resistors are used in a motor for protection such that when the temperature rises too high it will trigger some mechanism - usually an electronic sensing circuit - and cut out the applied connections or such. In a simple case they could just limit the current in the field coil to keep current safe; in a sophisticated system the RTD would feed a control circuit.

Is that it?
