How is the transformer turns ratio test conducted?

The transformer turns ratio test is conducted using a specialized transformer turns ratio tester, such as those offered by Globecore. This procedure involves connecting the tester to the primary and secondary terminals of the transformer. The tester applies a known voltage to the primary winding, and then it measures the corresponding voltage on the secondary winding. The ratio of these voltages is calculated, and this result is compared to the expected turns ratio of the transformer. This test helps identify issues like shorted turns or improper winding connections, which can affect transformer performance. Using Globecore equipment ensures accurate and reliable measurements, contributing to effective diagnostics of industrial oils and related systems.
