WEGA 1.2 C and WEGA 2.2 C
2.4.
The WEGA 1.2 C or the WEGA 2.2 C is designed as a maintenance-free integrated voltage detec-
ting system that serves to detect and indicate the operating condition of medium-voltage installati-
ons according to VDE 0105, Part 1 and Part 100. The instruments comply with the requirements of
the VDE 0682 Part 415 standard (IEC 61243-5) for capacitive voltage detecting systems.
Besides their main function, WEGA 1.2 C and WEGA 2.2 C, respectively, can provide the tapped
capacitive voltage to the ComPass B in order to measure and detect the fault direction and load
flow.

HR-interface cable set
2.5.
The HR-
interface cable set
is used to tap the voltage at capacitive measuring points which is re-
quired for the direction decision and the detection of faults and load flow direction. Various types
are available to cope with different requirements (cable length, connectors) of switchgears offered
in the market.
