Description

The SSVT is a voltage transformerinsulated in oilthat combines the characteristics of a voltagetransformer with power transformation capability.The SSVT has been designed for voltage up to 362kV and with powercapability up to 333kVA. SSVT converts the optimum power directly from high voltage side to medium/low voltage side.

The SSVT feature rugged transformer designs incorporating high creepage porcelain insulators and high over-voltage capability with impedance protection to limit fault currents. The SSVT is a line-to-ground connected single-phase transformer that can be used either as an individual unit for supplying single-phase loads, or in a three-phase bank to support larger kVA three-phase loads.
