The Rogowski coil is used for measuring currents and is primarily used for retrofitting in existing installations – with a choice of either on busbars or large cable cross sections. It delivers a voltage output proportionate to the current measured (e.g. 1 mV/A). It is also perfectly suited for installation in areas that are difficult to access or where space is limited.

• Easy retrofitting without separation from the primary circuit
• Ideally suited for measuring high and high-frequency currents
• Flexible and easy to install
• No extra power supply required compared with active Rogowski coils
• Suitable for the UMG 96-PQ-L-LP (up to 8 kA)
• Output signal: e.g. 100 mV/kA @ 50 Hz (RMS values)
• Inside diameter: Up to 580 mm - with bayonet fasteningConnection cable: 3 m
• Positioning error: +/- 1%
• Frequency range: 40 Hz to 20 kHz
• Rated insulation voltage 1 kV CAT III
