ABSTRACT
Here we discuss the phenomenon of transformer inrush; what it is and its significance to transformer protection design.
INTRODUCTION
A couple of years ago in this Transformer Special Edition, we wrote an article that covered the most used transformer protection schemes. As was pointed out in that article, protective systems have two jobs. They must detect conditions that endanger personnel and equipment, But they must also allow the normal and expected power system and...
By R.W. Hurst, Editor A distribution transformer is a critical component of the electrical power system, used to reduce the voltage of electrical energy for electric power distribution to end-users. It plays a vital role in voltage regulation and load management, ensuring the efficient and reliable...

By Chuck Hoeppner, Delta-X Research It’s often said that you can’t manage what you can’t measure. But how does one manage risk in the mission-critical, 24x7 world of energy utilities? It’s a challenging undertaking, anticipating future demands and ensuring the reliability...
In a significant move for Pennsylvania’s energy sector, State Senator Gene Yaw has introduced a transformative piece of legislation aimed at modernizing the state's approach to power plant development and capacity management. The bill, which has been the subject of considerable discussion,...
The Growing Need for Safer and Greener Transformer Oils Transformer oil plays a vital role in the operation and longevity of power transformers, providing insulation, cooling, and arc suppression. Traditionally, mineral oil has been the industry standard due to its effective dielectric properties...
The Growing Concern of Transformer Fire Risks An Electrical Substation Transformer is a critical component of modern substations, playing a vital role in the transmission and distribution of electricity. However, due to the high-voltage operations, flammable insulation materials, and exposure...
The Growing Transformer Supply Crisis The global transformer supply chain is facing unprecedented challenges, with utilities worldwide struggling to procure essential equipment due to material shortages, manufacturing delays, and logistical constraints. Transformers are the backbone of electrical...
Power transformers are critical assets in electrical transmission and distribution networks. Their failure can lead to widespread outages, costly downtime, and potential safety hazards. As transformers age and operate under varying electrical and environmental stresses, degradation becomes...
S.E., Inc. has been providing the very best in Transmission Powerline Construction for over (40) years throughout the Western United States. Brothers Mark, Steve, David, and Craig Sorenson have decided to retire and pursue other interests. Everything in the auction is owned by S.E., Inc. and will...
Monitoring the health of bushings is vital for ensuring the reliability of transformers, especially in high-stakes environments like power grids and industrial facilities. Bushings, critical components of transformers, are prone to various failure modes that can lead to operational inefficiencies...
