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 ...

Motors and generators are critical components of electrical systems. They are used to automate numerous industrial processes, circulate liquids for cooling and lubrication purposes, and generate ...

If you have power factor correction capacitors, should you skip insulation power factor testing on your transformers? The answer is "no." Those PF capacitors have no bearing on the question. This is a ...

Plant performance measurement often stops at the point where power enters the plant switchyard. Yet minor transformer failures can have devastating impact on plant performance and system reliability.

The power factor measurement has long been accepted as an invaluable tool for identifying insulation defects, such as ageing, deterioration, moisture ingress and localized failures, involving the ...

Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, inefficient lighting, equipment that is always left on when ...

Linear Technology Corporation’s LT3798 is an isolated flyback controller with single stage active power factor correction (PFC). Efficiencies greater than 86% can be achieved with output power levels ...
