Sheath Fault Locator
Sheath Fault Tester is a powerful system. It is an intact sheath of a plastic insulated medium, high or extra high voltage cable is the prerequisite for the avoidance of water ingress and subsequent cable faults. Different test can be carried using sheath fault locator. Sheath/earth faults is develop in any type of underground cable network such as low, medium, high voltage power cables or unshielded multi core control cables.
