Direct measurement of Voltage or current in high voltage units like AC is not possible because of insulation problem of measuring instruments. In such conditions, Potential transformer is used(PT). It is vacuum encapsulated in epoxy resin, which make sure faultless insulation. Incombustible best in class raw material, along with uniform cast resin bodies, gives our 33KV Resin Cast PT high mechanical and electrical strength. Moreover, it is used to isolate the Measuring Instruments, Relays, Meters.
