33KV RVT POTENTIAL TRANSFORMER

Made up of the finest grade material and cutting-edge technology, our products have seamless quality. We are one of the leading manufacturer of RVT of any class, ratio and burden. Our RVT are quality product as per IS / IEC. We can manufacture RVT of all types up to 33 KV voltage class as per customer requirement on most competitive prices. Residual voltage transformer is used to detect unbalanced voltage in three phase system & to supply voltage to directional earth fault relay. For directional earth - fault relay. It is necessary that the voltage applied to the voltage coil of the relay corresponds in phase to that of the current in current coil such voltage will be the residual voltage of the system & will be the phasor sum of the three line - to - earth voltages. Residual voltage can be achieved by connecting secondary of three single phase V.T. Connected in three different phases, in open delta fashion. It is, however, economical to use three phase V.T. Instead of three Nos. Single phase R.V.T. Suitable up to 33 KV system voltage. In normal three phase three limb V.T.
