Oil Filled Current Transformer

ITEC CTO current 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 manufactured 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 corrosive and contaminated environments.

All CTO’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 transformers. Bushings are design to exceed the IEEE standards for creep and strike distances. The standard bushing color is ANSI 70 light gray.

CTO’s are designed to provide 0.3% accuracy class at IEEE burdens of B0.1 through B1.8. High Accuracy 0.15 and 0.15s class designs are available at B0.1 through B1.8 Burdens. Extended range designs are available outside the standard ranges specified in IEEE C57.13 for renewable power applications. Please contact the factory for a design that meets your specific requirements.

Applications include revenue metering, protection and control, power quality and monitoring.
