The station service voltage transformer (SSVT) is a voltage transformer insulated in oil that combines the characteristics of a voltage transformer with power transformation capability. The SSVT has been designed for voltage up to 245kV and with power capability up to 333kVA. SSVT converts the optimum power directly from high voltage side to medium/low voltage side.
The SSVT features 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.
