Now with the help of variac, applied voltage gets. Some heavy transformer testing is also carried out in the client location prior to commissioning. The oscillator�s ac signal tests the integrity of the primary and secondary windings; Connect an ohmmeter across the two ends of the secondary winding of the transformer and record the resistance. Welding transformers feature a primary and secondary coil, as is described in the book welding principles & applications. The hv side of the transformer is kept open.

The type and routine test are very important for transformer.

Welding transformers feature a primary and secondary coil, as is described in the book welding principles & applications. Since the transients are impulses of short rise time, the voltage distribution along the transformer winding will not be uniform.the equivalent circuit of a. Mainly two types of transformer are done by manufacturer before dispatching the transformer mainly (1) type test of transformer and (2) routine test. As power transformer is highly expensive as well as important part of distribution system. The purpose of the impulse tests is to determine the ability of the insulation of the transformers to withstand the transient voltages due to lightning, etc. No matter what the type, winding resistance testers are always equipped with a current output, voltage measurement, and resistance meter.
