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, ...

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 ...

Part 1 of this three-part series laid out an overview of a proposal to create a numerical health index and establish a practical program for power transformer maintenance. Part 2 breaks down each of ...

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 ...

To prevent similar situations in the future, Chinese engineers have now developed a 750-megavolt-ampere (MVA) smart DC ...

It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

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%.

Are the benefits of digital integrated power transformers worth it? Smart transformers with exciting new technologies like Internet of Things (IoT) and artificial intelligence (AI) are among the next ...
