Success story: Retrofit substation automation system (SAS) in 400/220 kV substation

In a previous blog, we introduced SCOPE’s Substation Automation System (SAS) capabilities and underscored the need for thinking beyond OEMs for complex SAS projects. We also discussed 3 crucial parameters to be kept in mind while executing SAS projects and highlighted how the SAS system integrators can effectively implement SAS projects in a manner which …

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 …

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 …

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 …

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: Health Assessment of Transmission Line Towers

When it comes to any infrastructure asset, regular maintenance is critical to ensure its optimal performance. This is especially true for complex infrastructure assets deployed by Utility companies that warrant the need for expert testing and maintenance carried out by specialists. In this post, we will cover how SCOPE’s services vertical - ISOSCELES Sales & …

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 …

Success Story: Testing & Commissioning Of India’s Highest-Altitude GIS Substations

Even after 70 years of India’s independence, the pristine regions of Ladakh and Kargil remained 95% power deficit. This was set to change in 2019 when state-run Power Grid Corporation of India Ltd. (PGCIL) activated its 220/66kV Gas Insulated Substations (GIS) in Leh, Khalsti, Drass and Kargil. Commissioned as a part of the Hon. Prime …

Success Story: Preventing Circuit Breaker Failure At One Of India’s Largest Electric Power Transmission Utilities

As elaborated in our previous post, Dynamic Contact Resistance Measurement (DCRM) tests play a pivotal role in preventing unexpected failures of High Voltage (HV/EHV/UHV) Circuit Breakers by cohesively assessing the healthiness of their contacts. Widely considered as the most comprehensive CB testing methodology, the success of any DCRM test depends on a trifecta of the …

Success Story: Optimizing Distributed Wind Power Assets’ Data

Overview Ever since India deregulated power generation in 1991 and power transmission in 1998, it has witnessed a steady influx of private Power Companies eager to set up power plants across the country. Our client, a major private Wind Power Producer, had established a large distributed asset base of 100+ Wind Parks across India with …
