H Nu's optical current measurement systems simplify your substation design, improve reliability and reduce cost.
H Nu™ FOCS solutions are an advanced, digital alternative to the conventional current transformer. Unlike conventional current transformers, H Nu™ FOCS solutions measure both AC and DC current and perform both revenue metering and protective relaying in the same device.
Producing a digital data stream, H Nu™ FOCS solutions are inherently compatible with the digital protocols and control systems used by modern networks (IEC 61850/61869).
Replacing extensive copper cabling with a single fibre-optic cable provides multiple benefits:
H Nu™ FOCS solutions do not contain oil or sulphur hexafluoride gas.
