How do you test a distribution transformer?
How do you test a distribution transformer? Each transformer manufactured by Power Partners must undergo a series of tests:Polarity, Phase-Relation, and Ratio.Applied Voltage Test of the HV.Applied Voltage Test of the LV.Induced Voltage Test.No-Load (Excitation) Loss and Excitation Current.Circuit Breaker Test (for CSP transformers only) How do you test a transformer to see if it's bad? To test your transformer, simply touch the red and black pins of your ohmmeter to the opposite ends of the transformer's wiring. Read the display and compare the resistance on your ohmmeter to the resistance stated on the transformer's data sheet. This is sometimes...
