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 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.

Revenue Grade CT’s

When precision and verifiable accuracy count, DENT’s Revenue Grade Current Transformers (CTs) deliver unmatched performance. Designed for the high-accountability applications, these CTs ensure exceptionally accurate signal transformation with low phase shift. Ideal for compliance with stringent regulatory standards and rebilling scenarios, our Revenue Grade CTs provide the reliability and precision you need.

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.
