INFORMATION

Description

Electronic residual current protection relay of the WG series, connected to the external transformers of the WG / WGC series. Superimmunized type relay with high frequency currents filtering and high immunity. True RMS measurement (TRMS).

  •  Data shown on the display
  • Features two independent programmable outputs (main and prealarm)
  • External input for remote-control functions (230 Vac)

Applications

The RGU-10 relays associated with WG transformers offer smart residual current protection. Their design features guarantee maximum security and electrical service continuity, avoiding unwanted tripping.

Viewing the instantaneous leakage value on the display, together with the prealarm indicators, makes it possible to obtain information on the status of lines to be protected, and to perform adequate preventive maintenance.

In addition, version RGU-10 C features RS-485 communications and, with the PowerStudio software, offers centralised supervision in real time, as well as keeping a log of historical data for future analysis.
