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 ...

With the IDAX-300 test set from Megger, you can assess the condition of the insulation in power transformers, bushings, generators, motors, and cables—a key indicator of future reliability and ...

Transformers are very reliable devices and can provide service for a long time if regularly maintained and serviced. They’re also the single most costly item in any substation. To protect against ...

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 ...

Bushings are bolted onto a transformer's turrets, which extend up from the main tank. A team of researchers at Idaho National Laboratory (INL) has focused on these connections. The team's goal is to ...
