Following successful final acceptance testing at the Siemens transformer factory in Nuremberg, the world’s first 800-kV transformer for extra-high-voltage DC transmission systems HVDC is ready for ...

To prevent similar situations in the future, Chinese engineers have now developed a 750-megavolt-ampere (MVA) smart DC transformer, the largest of its type in the world. Designed to handle grids with ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Achieves 1% accuracy for CTs up to 8000 amps, ensuring precise metering and billing with traceable, reliable results. By automating the testing process and integrating real-time data management, the ...

This file type includes high resolution graphics and schematics when applicable. Certifying a new power product to relevant safety standards is an essential part of any design and development process.

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

Oftentimes the biggest obstacle indesigning an isolated dc/dc converteris the transformer design, a prospectthat sometimes discourages designersfrom undertaking an otherwisestraightforward design task ...
