The electric power industry is always looking for the best approach to better determine and continually track the condition of power transformers. It is important to understand the need for and value ...

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 ...

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 ...

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 ...

Regulatory institutions all over the world have started noticing the problem of creeping standby power for electronic products that plug into a wall socket. Committees like the International ...

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 ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...
