Hr-Interface Cable Set - Horstmann ComPass B Instructions For Use Manual

Dipl.-Ing. H. Horstmann GmbH
• Split core summation current transformer for earth fault detection, for cable diameters ran-
ging from 40 to 105 mm (Order No.: 49-6023-xxx).
Make sure current transformers are mounted only on fully insulated i. e. touch-safe conductors.
2.4. WEGA 1.2 C and WEGA 2.2 C
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

interface cable set
The HR-
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.
