Description

The advanced monitoring solution for monitoring partial discharge and temperature in medium-voltage switchgear uses surface acoustic wave and ultra high frequency sensing technology. It features an integrated IIoT platform to improve the safety, efficiency and durability of medium-voltage switchgear.

By using condition monitoring systems, approx. 75 % of disruptions can be prevented through early fault detection, thus reducing both maintenance costs and intervals.

Special features

  • Easy to install and commission
  • Maintenance-free
  • Comprehensive data communication (local, remote, Modbus ® , SCADA, IIoT service)
