information for proper maintenance.
Under normal operating conditions the backlit display is green. However, after any event caus-
ing a main relay to trip, the backlight is red, indicating the reason.
The version for RS-485 communications (RGU-10C) and appropriate software allows setting,
data and information to centralised for the proper monitoring and checking of the maintenance
of electricity lines.
The measurement of earth leakage current from which the RGU-10/RGU-10C operates by
indicating the instant leakage current, pre-alarm or trip is determined by the WGC series earth
leakagetransformers.Theinnerdiameterofthetransformerisdenedbytheinstallation’swir-
