An In Depth Understanding of Power Factor Testing In The Field
This 1-Day class will give the student attendee a more in depth understanding of Power Factor testing in the field. The Power Factor measures the insulation in the transformer. The insulation system is the weakest link in the transformer and can deteriorate over time. At some point, the dielectric strength of this insulation can be compromised and the insulation will fail. The Power Factor is a measurement of the efficiency of the transformer's insulation system and therefore a reliable electrical test to detect deterioration that may cause significant issues with the operation of the transformer. This course will also cover Power Factor Testing of bushings and circuit breakers.
