- Fault locating - Identify characteristics of cable system and types of faults. Select and utilize appropriate equipment and technology to locate fault.
- Fault location on power cables Gain insight into specialised fault location and pinpointing proceedures for high voltage power lines. Look at the construction of high voltage cables, as well as the methods and practices that are becoming new the standard, such as condition-based preventative maintenance.
- Cable test and fault location equipment Cables can be highly capacitive, so testing the insulation often requires a significant power output from the test equipment. Many cable test systems are therefore quite large as a result.
- TDR basic operation A TDR (time domain reflectometer) uses the radar principle to identify faults on cables. This paper shows how to operate it correctly.
- Using a TDR to find cable faults without applying a high voltage Although you will still need a combination of test instruments including an insulation test set, in the right circumstances, a TDR can sometimes locate cable faults without the need to apply a high voltage to the cable.
- Sheath testing for fault location Water ingress caused by damaged cable sheaths is a leading cause of faults in plastic-sheathed cables. Proper cable maintenance through sheath testing can extend the life of the cable by preventing the long term damage caused by water ingress. This article covers best practices and best equipment to use when sheath testing.
- Best practices for offline diagnosis of medium voltage cables The necessity for both commissioning testing of new cables as well as diagnostic measurements as part of a condition based maintenance is just a logical given fact. Nowadays cable testing as well as condition monitoring are well proven measurement methods for MV power cables which are guided by IEEE 400 [1] and IEC 60502-2 [2] standards.
- Advanced knowledge - Application of appropriate insulations, shields, and jackets.
- IEEE 141 Recommended Practice for Electric Power Distribution for Industrial Plants
- Water Trees are Significant [PDF] Considerable interest exists in the chemical composition of water trees in electrical insulation because of the information it provides about the mechanism of treeing, the possible prevention and detection of this hazard, and the longevity of cable insulation.
- Diagnostics of water tree deteriorated XLPE cables It has been shown that the dielectric response of water tree deteriorated XLPE cables can be recognised and classified into different types of responses related to the ageing status and breakdown strength.
