Rogowski Coil CT's | RoCoil Flexible Rope Current Transformers

DENT's IEEE Class RoCoil line of Rogowski Coil CTs offer significant advantages over conventional Split Core or Clamp-On CTs in certain installations. These "rope-style" current transformers deliver "installer-friendly" features such as large window size, light weight, wide current range, and mechanical flexibility for mounting in tight quarters. RoCoils provide accurate, non-intrusive measurement of AC combined with easy placement around cable bundles, large bus bars, and irregularly shaped conductors.

RoCoil CTs are designed for use with ANSI C12 Class meters such as DENT's PowerScout Series instruments. They are also compatible with DENT ELITEpro XC meters. This Rogowski-type sensor produces an output signal (di/dt) of 131mVAC per 1000A at 60 Hz (110mVAC/1000A @ 50 Hz). Performance of these CTs meets or exceeds IEEE C57.13 Class 1.2.

These CTs require a customer-supplied integrator/amplifier, such as the one built into DENT's ELITEpro XC and PowerScout instruments. Contact DENT Instruments to determine compatibility with other products. 

Four lengths available: 16", 24", 36", and 47".

3M leads standard. 16", 24", 36" models available with optional 7M or 15M leads. 15 meter leads require additional lead time. Please contact the factory for ordering information.

All DENT CTs are sold individually (not in sets).
