Product Description

Power protection and control equipment are used to monitor the voltage to a load to ensure it is within specified bounds. If an out-of-bounds level is detected, a protection and control devices can either regulate the voltage or current or switch off the power source to protect the load from damage.

Important  Features

• Accurate voltage and current measurement

• High insulation strength and long service life

• Oil-paper or SF6 insulation options

• Outdoor and indoor models available

• Designed to meet IEC 61869 / IEEE C57 standards

• Suitable for GIS and AIS substations
