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 …

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 …
