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 …

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 …

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: Commissioning Of Phasor Measurement Units (PMUs) For A Central Transmission Utility

The 2012 grid collapse in India resulting from excess power usage by some states prompted the authorities to conceptualise the idea of ‘One Nation One Grid’ by monitoring and analysing the real-time power usage data at the regional and national level.   To achieve this, Synchrophasor technology is widely used across India for real-time data …

Decoding The Indian Electricity (Amendment) Bill, 2020

The Indian Electricity Act, 2003 (EA 2003) is widely hailed as a landmark piece of legislation that reformed and rejuvenated the power sector in India. The Act ushered in competition in the power sector by permitting the entry of private players, restructuring State Electricity Boards into separate companies for power generation, transmission and distribution, streamlining …

FAQs on Testing and Measuring Lightning/Surge Arresters

In our previous post, we deep-dived into the various techniques and methodologies that are widely adopted for assessing the healthiness of Lightning/Surge Arresters. In this post, we will answer the 10 frequently asked questions (FAQs) on the various aspects of testing and measuring Lightning/Surge Arresters. Let’s begin! FAQs: 1. What are Third Harmonics? A. In …

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 …
