Protection and Measurement

Proactive Grid Management Begins with Protection and Measurement Sensors

As the distribution grid evolves with the increasing integration of distributed energy resources (DERs), voltage and power factor values can fluctuate much more frequently. G&W Electric accurate and precise sensors enable crucial continuous measurement of local voltage levels and phase angles to help detect potential grid instabilities or disturbances. Our advanced sensor technology using Rogowski coils and capacitive dividers, offer early warning systems, compliance monitoring, Volt-VAR optimization, fault detection, relay protection, and monitoring and control.

Sensors for Recloser Platforms

G&W Electric’s highly accurate and precise sensors are engineered as a lightweight enhancement to our distribution recloser platforms, providing exceptional current and voltage monitoring, measurement, and protection against faults and instabilities. The recloser automatically restores power after temporary faults.

VIPER®-ST

G&W Electric’s Viper®-ST independent pole operated (IPO) recloser combines the time proven reliability of electronically controlled, vacuum fault interrupters with the maintenance-free benefits of a solid dielectric insulated device.

Sensors for Padmounted, Vault, and Subsurface Switchgear Platforms

Whether your distribution switchgear is designed for indoor or underground use, our high-precision sensors make fault measurement and protection both simple and cost-effective. G&W Electric’s switchgear offers rapid response times, enabling quicker decision-making for seamless switching between power sources without any downtime or disruption.

SF6 Switchgear

Our line of gas insulated switchgear is available with load break and/or fault interrupters and is designed and tested to IEEE standards. It’s ideal for harsh environments where submersibility is required for operation on distribution systems rated up to 38kV, 900A continuous current and 40kA asymmetrical momentary current.
