7 Step: How Find Cable Fault Location

How to Find Underground Electrical Energy Transmission Lines Cable Faults?

Finding the faulty point of an underground cable doesn't have to be like finding a lost item on the street. There are many fault locating methods depending on who finds the fault, and how they want to find it. Detection technologies are now much easier to find the cable fault; also important is the technique applied, which makes the task much easier and less time-consuming. However, we can say that there is no single method or combination of methods that is universal. Skilled technique and proper tool selection are the key points to finding the cable fault more easily and within a minimum time.

What Is the Meaning of XLPE?

XLPE is an abbreviation for cross-linked polyethylene. The cross-linked polyethylene structure is formed by creating direct links or bonds between the carbon backbones of individual polyethylene chains.

Excavation and Civil Works for Underground Cable Laying

Clearing and Grading Excavation Routes

The routes of all cable excavations shall be cleared and leveled so that on completion of the works, the finished reinstated ground level shall be the same as that obtained prior to the commencement of the Works.

Method of Tower Grounding | Electrical Transmission Line

What is the purpose of a tower grounding?

Not only is tower grounding, but it is also fundamental and essential in an electrical system for both the safety and reliability of the system. 

The most important part of grounding is to protect people, structures, and equipment since damage can cause outages or malfunction and result in economic losses of great value. 

Allowable Earthing Resistance for Link Box Earthing

The allowable earthing resistance for a link box depends heavily on the type of bonding system (solid vs. cross-bonded) and the location of the link box (at a termination vs. along the cable route).

There is no single "universal" value, but standard industry specifications and practices typically require the following limits:
