PST-650

Oil Filled Station Voltage Transformer

ITEC PST station voltage transformers utilize high permeability, grain oriented silicon steel cores designed to optimize the performance and physical size of the transformer.

The transformer tanks and expansion chambers are manufacturered from mild steel and finished with the latest powder coating technology to withstand the most rigorous environmental conditions. The standard finish color is ANSI 70 light gray. Stainless steel is available as an option for corosive and contaminated enviroments.

All PST’s are hermetically sealed, full vacuum assemblies provided with a dry nitrogen cushion.

One piece, wet process porcelain bushings are used on all ITEC oil filled transfomers. Bushings are design to exceed the IEEE standards for creep and strike distances. The standard bushing color is ANSI 70 light gray.

PSTs are available in with power windings only or power windings with optional metering windings. Metering windings are availble having either single or two tapped windings and are designed to provide 0.3% accuracy class through burdens of W, X, M, Y, Z and ZZ. Single power ratings are available form 10 kVA through 167 kVA in all voltage classes.

Applications include auxiliary station service power and remote site power and monitoring.
