DESCRIPTION
With the new Variant series, Megger provides a fully
equipped measuring station for all VDE-compliant cable testing and fault location on PVC, PE, VPE and paper-insulated
cables in the voltage range up to 33 kV.
System components:
During the development of the Variant system, special attention was paid to reliability and availability:
■■Teleflex VX with ARM® multi-shot technology
■■A fail-safe, modular system
■■easyGO® and expert operating mode
■■Emergency operation in case of system control failure
The system also has the advantage of being simple to service.
Heavy extension reels come installed so they can be easily
extended. Electronic components are in place so that testing and calibration can be easily performed from the control
room.
■■System control with operating mode switch, phase switch
and safety system
■■Surge generator up to 3500 J
■■HV operating unit BPS
■■ARM® filter ARM 300
■■MFM 10 sheath fault location system
■■FLG 200 audio frequency generator
■■Ergonomic work station with desk and drawer cabinet
