DENT's 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 irregular shaped conductors.

RoCoil CTs are designed for use with DENT's PowerScout Series and ELITEpro XC Series instruments. This Rogowski-type sensor produces an output signal (di/dt) of 131mVAC per 1000A at 60 Hz (110mVAC/1000A @ 50 Hz). Revenue grade 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".

Parts: CTR16A4U, CTR24A4U, CTR36A4U, CTR47A4U
