Answer / rajkumar

current tr, (voltage tr---1 phase, 3 phase---LT, HT)and power tr
current tr--- used mainly to measure current flowing in a
conductor(current flowing conductor is primary and you will
get mA in secondary coil which you can use for measurement)
voltage Tr----to boost or reduce voltage ..ie if you apply
low voltage in primary winding you can get high voltage at
secondary winding and vice versa according to winding
designs. core and shell are designed to minimise tranform
losses.
power Tr---tranforms both current and voltage ..winding with
electronics to boost or reduce power

A pressure differential gauge type of instrument has a manifold with 2 isolation valves (hp and lp),2 vents(1 each for hp and lp) and 1 equalizing valve. Determine the position of each valve(either fully closed or fully open) when troboulshooting to: 1. zero the transmitter. 2. determine if there is a block in the impulse line. 3. determine if the gauge is functioning properly. The process fluid is water.
