Megger Variant Cable Test Van

  • Product Description
  • Specifications
  • Features

The Variant is a modular three or single phased system for testing and fault location on power cables in low and medium voltage networks.

The variant offers a maximum variability in the equipment options and features of a cable test and fault location system.

The flexibility of the variant permits a very specific customer suited adaptation of the systemfor cable testing, surge energy for the pinpointing, burning and sheath fault location.
 
The variant features flexibility to individuals adapted key parameters for cable testing, surge energy for fault pinpointing, burning and sheath fault location to the operators needs.
 
Standard featres of the classic system are 80 kV DC test voltage, ARM cable fault prelocating methods up to 32 kV
