Medium Voltage Indoor Sensors

Medium voltage sensors for indoor applications

The ABB solution for measuring currents and voltages for protection and monitoring in medium voltage power systems.

Electronic Instrument Transformers (Sensors) offer an alternative way of making current and voltage measurements. Sensors based on alternative principles have been introduced as successors to conventional instrument transformers in order to significantly reduce size, increase safety, and to provide greater rating standardization and a wider functionality range. These well known principles can only be fully utilized in combination with versatile electronic relays.
