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 ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

Among the various diagnostic methods used to assess transformer condition, capacitance and Tan Delta testing has gained broad acceptance as an effective means of evaluating insulation health. By ...

BAODING, HEBEI PROVINCE, CHINA, January 19, 2026 /EINPresswire.com/ -- In the rapidly evolving global power and energy ...

In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

With the new MCT1605 test set from Megger, comprehensive testing of current transformers – including multi-ratio types – can be carried out quickly and easily. With a single push of a button, the ...

Engineers whose work involves testing in substations face two important challenges. The first is having the right equipment at hand to carry out the wide range of tests that are often required, and ...

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 ...

Using a transformer coupled differential inverting amplifier stage can give a very low input referred noise voltage or Noise Figure (NF) with exceptional SFDR/mW. The NF equation needs to include ...
