Load Survey
DENT current transformers for metering are available in two accuracy classes: Standard Accuracy CTs provide 0.5 – 1% accuracy for general metering projects while Revenue Grade CTs (<0.2% ratio error) are ANSI-certified to provide best-in-class accuracy for revenue metering (billing) applications with the Revenue-Grade PowerScout Series meters. Choose from split core current transformers, clamp on current transformers, or Rogowski coils.

Flexible Rope Current Sensors
RōCoil | Rogowski Coil
DENT’s RōCoil line of Rogowski Coil Current Sensors offer significant advantages over conventional Split Core or Clamp-On CTs in certain installations. These flexible “rope-style” current transformers deliver installer-friendly features such as a wide current range and flexibility for mounting in tight or limiting quarters. RōCoils provide accurate, non-intrusive measurement of AC combined with easy placement around cable bundles, large bus bars, and irregularly shaped conductors.

For Field Studies
EZ Clamp | Clamp-On CT
DENT’s 150A Split Core EZ Clamp-On Current Transformers are the fastest and most convenient way to get temporary measurements in the field. Designed for one-handed operation, they quickly clamp around insulated cables or wires. These CTs pair exceptionally well with the ELITEpro XC Portable Data Logger, making them ideal for portable Measurement & Verification (M&V) studies. Typical applications also include electrical load profiling, energy audits, and new technology assessment studies.
