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 ...

SURGE ARRESTERS ARE OFTEN OVERLOOKED WHEN PERFORMING POWER FACTOR TESTS on transformers, breakers and other apparatus in a substation. Oftentimes, the testers are aware of how a transformer or a ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

We hear it all the time — America’s electrical infrastructure is aging. Coupled with that reality, one of the issues that continues to surface around this ongoing discussion is knowing the reliability ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...
