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 ...

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 ...

With the 2020 revision of the NEC, Art. 242 replaced two individual Articles that appeared in earlier editions of the Code — Art. 280 [Surge Arrestors] and Art. 285 [Transient Voltage Surge ...

For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...

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 ...

This application note presents different types of overvoltage protection devices for solid-state relays. The document also provides suggested recommendations on their selection and use with the Vishay ...
