Easy retrofitting of current-measuring technology


Rogowski coil current measurement offers safe alternative to split-core current transformers

MIDDLETOWN, Pa. – Phoenix Contact now offers a Rogowski coil solution to easily retrofit current-measuring applications up to 4000 A. The PACT RCP current transformer (CT) is an alternative to split-core current transformers and other CT technologies.

The Rogowski coil is a flexible, rope-styled CT. Because it is designed as a loop, the Rogowski coil can be separated easily for quick installation on an existing busbar or wire. The user does not have to remove system parts, which reduces expensive downtime. The Rogowski principle eliminates the dangerous open-circuit voltages inherent to split-core CTs and the need for CT shorting blocks.
