For many years the limit for normal apparatus loading was based on the maximum nameplate rating or an arbitrarily set value, called ‘the red line’.
On-line monitoring of power transformers and circuit breakers for condition assessment has gained popularity over the past twenty-five years, the typical technology adoption period, from concept to commercial reality in the electric utility industry.
What are the benefits of implementing End-to-End monitoring of power transformers and
circuit breakers?
To fully assess the functionality of medium and high voltage circuit breakers, various mechanical and electrical parameters must be tested. Gas-insulated switchgear (GIS) in particular poses unique and special challenges, including the connection of the test equipment. In today‘s world, where...
Dissolved gas analysis (DGA) in transformers is a very successful periodic screening method to identify transformers that may be having problems. It is a symptom-based assessment of health, rather than a condition-based assessment. That is because the gases themselves do not cause failure, but are...
In today’s society we are faced with many obstacles, one of these obstacles is the high cost of electricity around the world. Electricity prices for commercial, industrial and institutional have increased a considerable amount. There are many reasons why this is occurring,...
As electrical systems age, operating costs increase while reliability dwindles. Given most utilities and industrial facilities are highly capital intensive and have limited financial and other resources to make wholesale equipment replacements, regular maintenance is critical for controlling the...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
High Voltage Direct Current (HVDC) technology revolutionizes long-distance power transmission, offering improved efficiency and reliability over traditional alternating current (AC) systems. This article explores the latest developments and applications of HVDC substations, providing a technical...
As substations become more interconnected and automated, they are increasingly vulnerable to cyberattacks. These critical nodes of the power grid are essential for ensuring a stable and reliable energy supply, making their protection paramount. Strengthening substation automation controls is key to...
The transition to renewable energy is reshaping the power landscape, with grid-scale battery storage systems playing a pivotal role in this transformation. These systems are crucial for balancing supply and demand, particularly at the substation level, where they enhance grid stability and...
In recent years, digital twin technology has emerged as a game-changer in various industries, and the power sector is no exception. Digital twins are transforming how substations are managed by creating virtual replicas that provide insights into performance and potential issues. A digital...
The electronics industry is experiencing rapid growth and innovation, with devices becoming more advanced and ubiquitous. As this industry continues to flourish, it’s crucial to consider the environmental impact of electronic manufacturing and the materials used in these devices. One area...
