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.
In a previous blog post, we shared our views on the importance of transformer testing and discussed: a) the principles of winding resistance measurement, b) OLTC condition analysis and c) our thoughts on the ideal kit for transformer testing. In this blog post, we will share our knowledge on assessment of possible winding & core …
Over the last twenty years, the telecommunications sector in India has undergone a major revolution. Today, India is the world’s second-largest telecommunications market with a subscriber base of 1.16 billion (Source: India Brand Equity Foundation). Over the next five years, rise in mobile phone penetration and decline in data costs is expected to add 500 …

Power transformers are one of the most expensive and critical assets of the power sector. In this blog, we will discuss [1] principles of winding resistance measurement, a common transformer test prescribed in various standards such as IEEE C57.12.90-2006 Clause 5, IEC 60076-1 Clause 10.2, IS 2026-1 Clause 10.2; [2] OLTC condition analysis; and [3] …
Studies show that in 2019, India was the world’s second largest producer of crude steel with a capacity of 111.2 MT. India’s finished steel consumption is also projected to rise from 99 MT (2018-19) to 230 MT by 2030-31. Furthermore, with the government’s view towards self-reliance, steel companies are ramping up steel production capacity. Therefore, …
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 …
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 …

Most of the Low-Carbon Technologies (LCTs) used today (mainly EV battery charging, rooftop solar systems and data centre loads) are all non-linear loads. Ohm’s law is not applicable to such loads, meaning that the current is not proportional to the voltage and fluctuates based on the alternating load impedance. Utilities face many problems as their …
Utility companies transitioning to Smart Grid operations can significantly benefit from real-time knowledge of the internal operating state of their assets. For power Transformers, the key parameters for optimal performance are oil and winding temperature indications (OTI/WTI). These two parameters are the key indicators of efficiency losses and constraint levels of the quantity of power …
