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, including the lack of energy efficient businesses, the need for further investments to hook up to other reliable and cheaper resources, and the lack of not being able to handle peak hours causing...
Sulfur hexafluoride (SF6) insulates medium- and high-voltage switchgears around the world. In its pure form, this non-toxic, inert gas helps the power transmission & distribution (T&D) industry operate more safely by extinguishing high-temperature arcs. With a much higher...
Determining mechanical condition of high-voltage circuit breakers BY JOZEF LEVI, Doble Engineering Company Life expectancy of a newly installed high-voltage circuit breaker is approximately 40 years. Throughout its life, under normal circuit conditions, the circuit breaker will operate less than...
Improving substation maintenance best practices for greater success BY BUDO MILOVIC, DV-Power Currently, substation maintenance—regular or emergency—operations and best practices must fit the utility’s goal of accomplishing more with less, in order to maximize assets and...
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...
