Cable Fault Locator

Underground cable faults cannot be avoided due to many factors such as road widening, infrastructure improvement, digging carried out for repairs of other underground utilities etc.

These faults generally take long time to detect and hence long time to repair the damaged cables and restore the power supply. Long outages cause heavy production loss to industries, revenue loss to power distribution companies and inconvenience to general public. This calls for quick fault location and restoration of power supply in minimum possible time.

An ordinary fault locating kit comprising of diagnosis set and pin-pointing equipment can take long time to locate fault point. SCOPE offers pre-locator instruments that can give the fault distance to help the operator for reaching the spot quickly and pin-pointing the fault in a short time.

CFL PL3, new generation Cable Fault Pre-Locator from SCOPE is the ultimate solution for locating underground cable faults in minimum time. It uses advanced technology for fault distance measurement which helps even an unskilled operator to locate the fault with accuracy.

CFL PL3 is an advanced fault locating instrument. Three operating modes offered by the instrument enable the operator to locate all types of faults on any cable in minimum possible time.Complex and difficult to locate nature fault are located by CFL PL3 with high accuracy. These features classify the instrument to be a part of fault locating kit of Heavy Industries & Power Distribution Company.
