Application: Direct measurement of voltage in High Voltage System is Not possible because of insulation problem of measuring instruments. It is also not possible to use direct voltage for the system protection purpose due to its high value and high insulation problem protective relays. Therefore voltage transformers are used to step-down the high system voltage to low standard value accurately in proportion to their ratio. Basic Functions of Voltage

Transformers Are: To reduce the line voltage to a value which is suitable for standard measuring instruments relays, etc. To isolate the measuring instruments, meters, relays etc. from high voltage side an installation To sense abnormalities in voltage and give signals to protective relays to isolate the defective system Construction Voltage Transformer Mainly Consists of Primary & Secondary winding Electromagnetic Core Bottom Tank & Oil Expansion Chamber Porcelain Bushing Primary And Secondary Winding Copper enameled wire is used for winding. Primary is wound with multilayer and graded insulation. The diameter and length of each layer is selected such that Surge voltage is distributed equally in all layers of the Winding. Multilayer Kraft Paper insulation is provided between winding layers. Stress equalizing shield is provided on last layer of the winding. H.T. Connection is brought out through metallic pipe. Secondary is separately wound and inserted in the primary winding as per the requirement. Winding and tapping of V.T. is done in dust-free atmosphere.

Description: We are one of the leading manufacturer of RVT of any class, ratio, 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 secondaries 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. Whe
