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 ...

Omicron’s new Votano 100 is the first voltage transformer testing and calibration system to combine mobility (total weight less than 33 lbs /15 kg) with the highest level of accuracy (precise ...

For the PDF version of this article, click here. The size, performance and cost of a power electronic system are closely linked to the like parameters of the magnetic components. Since custom power ...

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 ...

So there I was with this mystery transformer on which someone put a label showing three different speaker load impedance, but with no indication of what the intended primary winding impedance happens ...

You can purchase test equipment that will allow you to examine the loop gain and loop phase properties of an operating feedback loop and, that purchased equipment will deliver useful results over a ...

Maintaining substation transformers isn't a new idea, but it's not always given the attention it deserves. Transformers will self-destruct over time, and failure to conduct regular transformer oil ...
