Rugged Monitoring

Sensors for Electrical Asset Monitoring

Measure what matters inside your electrical assets.

Expertise for your application.

Reliable condition information begins at the asset. Rugged Monitoring IIoT sensors collect electrical and thermal measurements that help reveal changes in equipment health.

The range supports transformers, rotating machines, switchgear, power cables and circuit breakers. Sensor selection can be matched to the parameter being measured and connected to a wider monitoring system.

Rugged Monitoring

Technology in context.

Sensor selection starts with the physical quantity, installation environment and monitor compatibility. Rugged supplies sensors for electrical-asset condition monitoring.

Explore the equipment and capabilities in our established portfolio. Model configuration and support can be discussed for your application.

Temperature sensing in electrical fields

TSENS uses GaAs fibre-optic temperature sensing, avoiding electrical interference at the measurement point. Applications include transformer windings, cores, busbars and tap changers.

Specify the installation details

Probe construction, cable length and connectors must suit the equipment. TSENS options address oil-filled and dry-type equipment, including arrangements that use insulating discs.

Applications
