Strong Points
Function
The RCSL (small) and RCLL (large) series flexible Rogowski coil current sensors are ideal for applications where regular current transformers will not fit. The flexible coil is designed to fit around multiple conductors, irregular bundles or busbars where rigid CTs will not fit. Five diameters and rated currents from 200 A to 5000 A allow the RCSL and RCLL to be used anywhere from residential monitoring to high-current three-phase industrial or commercial applications. The RCSL and RCLL has an internal integrator signal conditioning circuit, eliminating the need for an external circuit. They provide a 333 mV output signal, compatible with DIRIS A-100/A-200 (333 mV models) and WattNode power meters or any third party meter accepting 333 mV current sensors. The ROG series is cULus 2808 listed, certified by Underwriters Laboratory (UL).

Advantages
Safe installation
The open-ended design facilitates installation without disconnecting electrical wires inside the panel. Built-in burden resistor provides 333 mV voltage output at the rated full scale current, eliminating the need for shorting blocks.
Safe locking mechanism
The locking mechanism prevents the loop from opening accidentally, guaranteeing continuous functioning and accuracy even under harsh conditions.
Flexible installation
The rope-style concept provide significant installation flexibility for cable bundles, busbars and irregularly shaped conductors, where conventional rectangular or rigid CTs will not fit.
Accurate
The RCSL and RCLL deliver excellent linearity and low phase-angle error, typically ±1.0% from 3% to 120% of rated current, essential for accurate power and energy measurements.
Applications
- Energy - Energy storage for grid services
