Strong Points
Function
The ROG Rogowski current sensors are flexible rope style AC current sensors available in four diameters (80mm, 120mm, 200mm and 300mm).
These Rogowski sensors deliver an output signal of 131 mV / 1000 A @60Hz, and are compatible with the DIRIS MCM power meters, with no additional integrator or power supply required.
The rope style and the low voltage output signal make them non-intrusive and ideal for retrofit applications with existing electrical panels having limited space.
They are ideal for applications with high currents, busbars and multiple sets of parallel conductors where conventional rectangular or rigid split-core sensors will not fit.

Advantages
Safe installation
- The open-ended design facilitates installation without disconnecting electrical wires inside the panel.
- Built-in burden resistor provides 131 mV voltage output at the rated full scale current, eliminating the need for shorting blocks.
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.
Safe locking mechanism
The locking mechanism prevents the loop from opening accidentally, guaranteeing continuous functioning and accuracy even under harsh conditions.
Accurate
The ROG split-core sensors deliver linear 0.5% accuracy across a wide current range, essential for accurate power and energy measurements.
Long lead wires
The ROG series come with standard 22-ft / 7m 3-wire output lead, ideal when the meter is installed remote from the electrical panel. This reduces the need for contractors to extend and splice wire leads which typically increases the risk of wiring errors.
