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.
