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 …

SF6 gas is used as the insulating medium for AIS / GIS Substations for its superior dielectric strength property. Besides, SF6 is colourless, odourless, non-flammable, chemically inert in nature and highly stable. SF6 leakage is one of the most common problems for a power utility where a GIS or AIS circuit breaker is installed. The …

In the last two blogs, we have shared our knowledge on the technique of controlled switching to enhance the life expectancy of assets in the electrical network and improve system stability. By discussing how life span of reactors, capacitor bank assets and power transformers can be enhanced through controlled switching, we have underscored the criticality …
In our previous blog, we discussed the technique of controlled switching, a widely used technique to improve the life expectancy of assets and system stability. We had seen how the life span of reactor and capacitor bank assets can be extended through controlled switching. In this blog post, we will continue our discussion on controlled …

The electricity sector in India has seen rapid growth over the past few decades. With installed capacity of 373 GW, India is able to meet the demand for electricity. As generation capacity has grown, an extensive network of transmission lines has also been developed for evacuating power produced by different electricity generating stations and distributing …
It is widely accepted that widespread adoption of renewable energy sources such as solar and wind into the electric grid will be key to meeting carbon reduction targets and achieving global clean growth ambitions. In a previous blog post, we saw how OrxaGrid's Low Carbon App enables building owners to quickly and accurately calculate the …
Are you a property owner with spare land-area facing the sun? Have you ever considered what benefits could you get from a proposed solar installation? Photo by form PxHere If you have answered yes to above, then you will accept that widespread adoption of renewable energy sources such as solar and wind into the electric …

In a previous blog on Health Assessment of Transmission Towers, we underscored the importance of regular maintenance in order to ensure the optimal performance of any infrastructure asset. Improper functioning of earthing and lightning protection system (LPS) would render critical infrastructure at electrical substations at grave risk. Therefore, it is crucial that routine testing and …

Studies show that over 85% of disruptive failures in high voltage (HV) and medium voltage (MV) equipment are Partial Discharge related. Partial Discharge (PD) activity provides evidence of deterioration in assets, which can propagate and increase, until the insulation is no longer able to withstand the electrical stress therefore leading to flash-over and finally equipment failure. Therefore, early detection …
