Success Story: Enhancing the Life Span of 500 MVA ICT through Controlled Switching Devices

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 …

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 …

Introducing Prima Series: The Lightweight Champion Of Primary Injection Kits

Primary (Current) Injection Kits – a crucial set of T&M instruments that measure the healthiness of Current Transformers (CTs), have been around for many years now. And while Primary Injection Kits have evolved over the years, three common challenges still remain with most Primary Injection Kits available in the market today: 1. They Lack An …
