Current Transformers, Phase : Single

Current Transformers (CT) are used for current metering and protection in high voltage network systems. They transform the high current on the high voltage side into low current (1 or 5 A) adequate to be processed in measuring and protection instruments (secondary equipment, such as relays and recorders). A current transformer also isolates the measuring instruments from the high voltage of the monitored circuit. Current transformers are commonly used for metering and protection in the electrical power industry. Features :

Meets all latest IEC and IS metering and protection classes, including special core classes (other standards available on request)

Low weight & minimum oil volume design. High accuracy up to 0.1 and 0.2s class

Rated primary currents up to 3000 A. Rated secondary current 1 A or 5 A

Rated short circuit withstand up to 40 kA for 3 secs

Highly refined and processed oil/paper insulation system. Available in both dead tank & live tank design

True hermetical sealing

Uniformly distributed secondary windings guarantee accurate transformation at both rated and high currents

Stable accuracy over a long period of time

Successful field experience since the manufacture of the first current instrument transformer in 2001

CTs are virtually maintenance free during a long lifetime
