Among the various diagnostic methods used to assess transformer condition, capacitance and Tan Delta testing has gained broad ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Dissolved Gas Analysis (DGA) is one of the most trusted diagnostic tools for assessing the internal condition of a transformer. By measuring fault gases dissolved in insulating oil, DGA reveals ...

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 ...

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 ...

The EZCT-S2 from Vanguard Instruments is a second-generation, microprocessor-based, current transformer set. The EZCT-S2 will perform the current transformer saturation test and the CT (current ...
