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 ...

With increasing pressure to lower costs, utilities are looking for tools to maximize the benefit of each dollar spent. Maintenance crews and engineers have a hands-on technical understanding but often ...

Electrica signature analysis (ESA) uses the magnetic field in the air gap of an electrical machine to evaluate power quality conditions. Dry and oil transofrmer types are subject to problems ...

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 ...

Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

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 ...
