Our Rogowski coil range can be used in similar circumstances to current transformers - in many instances they have added advantages including:

• Wide dynamic range
• High lineraity
• Very useful with large size cables or awkward shaped conductors or in places with limited access
• No danger from open-circuited secondaries
• No damage by large overloads
• Non-instrisive - do not draw power from the main circuit carrying the current to be measured
• Light weight

Any number of meter combinations are available (up to 32 per modem) – please contact us for further details on our bespoke remote monitoring kits
