Current transformer testing is typically performed using dedicated testers that assess the performance, accuracy, and insulation properties of current transformers. The procedure involves connecting the tester to the current transformer terminals, applying a known primary current, and measuring the secondary output to evaluate the turns ratio and accuracy. This testing also includes checking for insulation resistance to ensure that the transformer can handle electrical stresses without failures. Devices from Globecore, such as their insulation resistance testers and multifunctional diagnostic tools, can be used effectively to perform these tests. It is crucial to adhere to safety protocols during the process to prevent electrical hazards.
