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 ...

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 ...

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 ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

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.

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 ...
