Transformers play a critical role in the electrical power system. Their primary purpose is to provide electricity at voltages levels that are appropriate for a specific application. In some cases, the application will be for the transmission or distribution of electricity, and will ultimately lead to providing electrical service at a useable levels for the end user.
The life of a transformer can be lengthy if appropriately tested and maintained during its course of service. However, the physical, electrical and thermal stresses that the equipment can potentially endure in the course of its service make it important to regularly assess the condition of a transformer’s electrical and mechanical components.
IEEE C57-152 suggests for following in relation to Field Testing of Transformers:
-
Power Factor
-
Core Ground
-
Insulation Resistance
-
Winding Resistance
-
Core Excitation
-
Transformer Turns Ratio and Polarity (TTR)
-
Sweep Frequency Response Analysis (SFRA) or Leakage Reactance
-
Insulating Oil
-
Dielectric Frequency Response
