Credits: https://media.licdn.com/dms For electrical manufacturing companies, ensuring the health and longevity of their cable infrastructure is paramount. Ageing cables pose a significant risk, leading to costly downtime, safety hazards, and reputational damage. Traditional inspection methods are often tedious, time-consuming, and prone to human …

Prelocation of Cable Faults Using Voltage Decay Method

Introduction In the previous blog, we discussed the ICM method used for prelocation of the Insulation Failure / High Resistance faults. To find out the distance of insulation failure / Very High Resistance faults in HV to EHV power cables, in which the breakdown voltage is greater than the Surge Generator's voltage the Voltage Decay …

Prelocation of Cable Faults using Time Domain Reflectometer Method

In a three-part series on underground cable fault location, we discussed various aspects of cable fault location – from types and causes of cable faults, methodology for identifying cable faults and finally, we illustrated the step-wise process for detecting faults in underground cables.  We also introduced the Time Domain Reflectometer (TDR) method for identifying underground …

Importance of Velocity of Propagation in TDR Method for UG cable fault location

In the previous blog, we concluded our three-part series on underground cable fault location. To review, we discussed the types of cable faults, methodology for locating cable faults, fault finding through Pre-location techniques and cable route tracing, pinpointing, cable identification and repair and re-test. In Part-2 of our 3 part series, we introduced the methodology …

Step-1 in underground cable fault finding: Pre-location Techniques

In the previous blog post, we discussed how electrical utilities are using underground cables to gain a higher degree of reliability. However, underground cable faults can lead to a long downtime, which can further lead to a major revenue loss for electricity utilities. We also discussed the various causes of cable faults and the different …

Introduction to Underground Cable Fault Location

Energy is a critical facet for human development. Studies evaluating the linkage of electricity and GDP growth estimate that 1% increase in per capital energy consumption results in an increase of per-capita GDP by 0.23%. Given this centrality, development of electricity infrastructure has been a key focus area for governments and policy makers. Power transmission …
