Why is understanding high-voltage oil-filled transformer bushings so critical? High-voltage power transformers are an essential component of our nation's electric grid infrastructure. Bushings are the ...

Bushings are the most critical component of a low-voltage (LV) transformer. They are important to the transformer’s operation because they are active parts. Unfortunately, bushing failures are the ...

The addition of flexural stiffeners on the transformer cover plates was explored as a means to stiffen the base of the bushings and mitigate their seismic vulnerability. Numerical and experimental ...

Keeping the nation’s lights on is no small job. The grid we take for granted involves large, expensive equipment, most notably power transformers. If one goes down, it can take more than a year to ...

Resin high-voltage insulators with a composite casing can mitigate explosion, fire and leakage in high power transformers, according to Paolo Cardano, transformer expert at power component maker ...

Electrica signature analysis (ESA) uses the magnetic field in the air gap of an electrical machine to evaluate power quality conditions. Dry and oil transofrmer types are subject to problems ...
