Power transformers are one of the most critical and expensive assets in electric transmission and distribution. An in-service transformer failure can have far-reaching consequences: extended outages, ...

With increasing pressure to lower costs, utilities are looking for tools to maximize the benefit of each dollar spent. Maintenance crews and engineers have a hands-on technical understanding but often ...

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 ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...

According to Texas Instruments, its latest high-density isolated DC-DC modules with integrated transformers shrink isolated bias power supplies in automotive and industrial systems by close to 90%.

Systems that require multiple output voltages typically employ flyback converters. In these multiple-output flyback converters, maintaining good regulation simultaneously on all output voltages is a ...

On the 5th, dozens of ultra-high-voltage transformers, each about 100 tons, that had finished final assembly were lined up at ILJIN Electric's Hongseong Plant 2, a comprehensive heavy electrical ...
