One of the major thermal power plants from Northern India was living with the problem of an undetected cable fault for over two years on their LT Cable. Since this cable was used for Street lighting and had a backup line which used to power up the street lights, this faulty cable went into the …
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 …

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 …

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 …
