Description

 

Clearly identifies the cores and their sequence in a three-phase power cable. Indication of the action to be taken to correct the core sequence, or to remove a fault on any cable core(s). Uses a transmitter unit with LED indicators at the measuring end, and an array of colour-coded diodes with connecting clips to fix the diode leads to the remote end of the cable to be checked.

The CCI is for use on DE-ENERGISED CABLES ONLY. Therefore correct operating procedures must be employed to ensure the cable is de-energised and any voltage discharged before connection of the CCI or its diode array.

Features

  • Indicates correctly matched cores & phase rotation sequences between ends
  • Indicates individual faults such as –

–  Two phases reversed

–  Phases rotated forwards / backwards in sequence

–  Earths in place on cable

–  Equipment connected to cable (not properly isolated)

–  Open-circuited or short-circuited cores

  • Self-test
  • For cables up to 33 kV, lengths up to 10 km
