With an increase in demand for electrical energy day by day, electrical installations, structures and systems are also increasing. It is very important to maintain these systems and equipment safely and efficiently. These requirements of the electrical system are fulfilled by the insulating material. The property of insulating material to oppose the flow of current …

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 …

Blog talks about the technique used in prelocation of Underground faults on cables especially with high resistance
Introduction In our earlier blogs, we discussed the prelocation using the Time Domain Reflectometry (TDR) method, for faults like low resistance, short circuit, ingress of moisture, and open circuit faults. Insulation failure / High Resistance faults cannot be determined using a low voltage source of a TDR or Prelocator instrument. In Mid Voltage (MV) to …

In our earlier blog on the transformer, we shared our views on how to detect possible core & winding damage using the Transformer Turns Ratio Meter. The oil which acts as the insulating medium is one of the reasons for internal transformer failure. The oil decomposes mainly due to Thermal, electrical & chemical stress due …

the monitoring and performance analysis of solar plants is the necessary part in the perspective of utility and industrial levels. The visualization of assets is more critical in the current scenario because if the visualization of assets is not scalable, robust and smooth it will increase the operation and maintenance costs.
The power utilities like generating plants, power transmission and distribution utilities, Industries etc. are the typical example of an operation technology (OT) landscape. Typically, in these OT industries, the field data are being handled on manual legacy methodology due to which there are numerous data being generated but are available in a silo and which …

It is accepted that industrial activity and the power sector are closely related. Industries use electricity supplied by Utilities through the grid network to power economic activity. While some industries use co-generation (as described in a previous blog) to power their operations, co-generation is not always viable. In a previous blog post, we reviewed 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 …
