SSVT inductive voltage transformers consist of a single-phase design intended for connection between phase and ground on 46 kV-362 kV HV grounded neutral networks to supply power to panels at low voltage or medium voltage.
The design allows for convenient siting within the substation environment for simple mounting to single phase supports. The SSVT is directly connected to the HV network and provides power to the panel within the substation, or to remote loads directly supplied for the HV service. SSVTs can provide output voltages from 120 V to MV levels (contact factory for specific output voltages). Power levels available range from 10 kVA to 167 kVA single phase supply for all system voltages, and as high as 333 kVA for 245 kV systems.
Station service voltage transformers can be supplied for power only, or power plus optional metering windings having either single or two tapped windings for voltage measurement. Hermetic sealing of the design is accomplished using a gas cushion above the oil to prevent free-breathing outside moisture-ladened air.
ANSI 70 gray insulators are supplied with high creep and high strike designs. Porcelain insulators are normally standard with polymer offered as an option, except at 362 kV, which has a standard polymer design.
