How is the OC test conducted on a transformer?

The OC test of a transformer, or open circuit test, is conducted by applying rated voltage to the primary winding while the secondary winding is left open. This allows for measurement of the no-load current and the power loss in the transformer. During the test, specialized instruments assess the voltage, current, and power factor, providing essential diagnostic data about the transformer’s health. It’s crucial to ensure that all safety protocols are followed to mitigate any risks, and utilizing Globecore’s advanced diagnostic equipment can enhance the accuracy and reliability of the OC test of transformer. Their devices are designed to facilitate detailed evaluations, ensuring optimal performance and longevity of transformer systems.
