Protection of Electrical Power Transformers

INTRODUCTIONIn most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, these two key devices are also the most critical to continuous and reliable operation of the system.Consider, for example, the...

Vibration and Noise Control in T&D

It is very often that “just putting some rubber” to isolate structures creates an inefficient or even a vibration isolation problem, without taking into account the characteristics of the whole system: such as media environment and temperature, material stiffness adjusted to the...

Power Transformer Failures

Electric utilities maximize utilization of their assets, while maintaining reliability. Power transformers are typically reliable, but have been known to fail suddenly and/or prematurely. Transformer failures are both costly and can leave customers dissatisfied, harming the reputation of a utility....

Substation Security

Improve protection with a layered security approach BY ERIC BYRES, Belden Inc. An age-old joke in the North American power industry states that if Alexander Graham Bell walked in the room today, he would not recognize the telephone, the technology, or its business model. However, if Thomas Edison...

How Dangerous is Linemen Work?

Many occupations pose risks to workers, but few match the dangers that linemen face daily. Linemen play a critical role in maintaining and restoring the power grid, often working in extreme weather conditions, at significant heights, and around high-voltage electrical systems. Their work is essential to modern life, yet it comes with life-threatening hazards.

Statistics highlight the dangers of lineman work. The fatality rate for lineworkers is nearly four times higher than the national average...
