Success Story: Earthing and Lightning Protection System Audit

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 …

Techniques & Methodologies For Health Assessment Of Lightning / Surge Arresters

Lightning / Surge Arresters are specialised devices that protect electrical installations and equipment from unpredictable electrical surges caused by internal events like electrical faults, switching, short circuits, etc. and external events like lightning impulses, lightning strokes, etc. Over the last few decades, Lightning / Surge Arresters have evolved from using Silicon Carbide to Zinc Oxide …

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 …

OrxaGrid – Enabling A Sustainable Energy Future

The United Nations, through its 17 Sustainable Development Goals (SDGs), has formulated a global agenda to spur economic growth while tackling climate change at the same time. Goal 7 of the SDGs directs member states to ensure access to affordable, reliable, sustainable and modern energy for everyone.  Low carbon technologies (LCTs) such as electric vehicles, …
