Transformer – Winding Resistance Test

Winding resistance test of transformers are very important test to perform at factory and at site. While transformers are transported, loded and unloaded it is important to check the following calculations during the testing of transformer prior commissioning, which can be carried out through winding resistance test. Calculations of the I²R component of conductor losses.Continue reading “Transformer – Winding Resistance Test”

Transformer Testing- Type Test| Routine Test

To ensure the performance and compliance of specifications transformer should go through various testing procedures. In general, testing of power transformer can be segregate into two part as on the basis of testings at manufacturer’s factory and testings at site after the delivery of transformer. Generally manufacturer’s perform routine test and type test directly orContinue reading “Transformer Testing- Type Test| Routine Test”
