Expanding the life span of Power Transformers through Controlled Switching

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 …

Expanding the Life Span of Reactor and Capacitor Bank Assets through Controlled Switching

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 …

Partial Discharge Testing: Need, Testing Methodologies and Addressing Defects

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 …

Success Story: Accurate Prediction Of Voltage Violation Alerts – On Time, Every Time.

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 …

Success Story: Optimising Transformer Efficiencies Through Automated Temperature And Load Analysis

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 …
