Instrument Transformers (CT & VT)
Current (CT) and voltage (VT) instrument transformers for LV and MV applications with customs metrological calibration.
Overview & Applications
Integra Metering Systems provides a comprehensive catalog of current transformers (CT) and voltage transformers (VT) for Low and Medium Voltage electrical installations, manufactured by certified partners such as FRER, Semar, SAEL, and Rayleigh Instruments.
Available in solid-core, split-core, and Rogowski coil geometries across classes 0.2s, 0.5s, and 1, our transformers are certified for fiscal tariff measurement and can be delivered with official UTF metrological calibration certificates issued by accredited laboratories.
