POTENTIAL TRANSFORMER

APPLICATION – Direct measurement of voltage in high voltage & high current system is not possible because of difficulty in electrical isolation of measuring instruments. Because of its high value, it is also not possible to use voltage directly to the system, so that Potential transformer are used to step down the high system voltage into low system measuring voltage with their proportionate ratio. due to this it is possible to measure high system voltage by using standard measuring instruments & relays, also its isolate meters, relays from high voltage systems and also to sense abnormalities in voltage & give signal to protective relay to isolate the defective system.
