Power factor testing alows for the detection of electrical equipment insulation problems without having to make an internal visual inspection. Thus, significantly decreasing the cost of maintenance and downtime. Power factor testing is one of the best techniques for preventive maintenance.
Power factor testing is generally used in factory testing and in the field for acceptance testing, preventive maintenance, and emergency diagnostic testing.
Applications of power factor testing include:
- medium and high voltage transformers
- circuit breakers
- lightning arrestors
- liquid insulation
- rotating machinery
- voltage regulators
