The new Transformer Bushing Monitor (TBM) system from Serveron, a BPL Global company, permits live power factor testing with no downtime, equipment removal, or off-line tests that fall short of ...

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 ...

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 ...

Motors and transformers are some of the most reliable pieces of equipment installed at power plants. However, inadequate maintenance can result in trouble. While regular testing and skilled evaluation ...

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.

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

Several switching-converter topologies exist for power converters that operate from the ac mains and must maintain a power factor of 0.9 or better. One topology is a boost converter with a control ...

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 ...
