Premium Series

Current
Transformer (CTs)

Powertech manufactures high-accuracy Current Transformers (CTs) designed for metering
and protection in medium voltage applications. Available in both resin cast and oil cooled variants,
these CTs are precision-engineered for indoor and outdoor installations.

Key Highlights

APG technology for resin casting

Advanced Pressure Gelation (APG) technique ensures uniform insulation and high mechanical strength.

Oil-cooled variants for high ambient performance

Ideal for outdoor and hot-climate installations, offering long-term reliability in harsh conditions.

Compact and space-saving designs

Small form factor fits into panels and switchboards without compromising functionality.

Versatile mounting options

Available with brackets and customizable terminals for flexible installation needs.

High accuracy for metering and protection

Supports both revenue metering and system protection with precision-rated cores.

Suitable for indoor & outdoor use

Robust insulation and casing options make it adaptable to varied site environments.
