What is the additive polarity test of a transformer?

The additive polarity test of a transformer is a fundamental method used to determine the polarity of the transformer windings, ensuring that they are connected correctly in a circuit. It involves connecting a simple circuit to the transformer and measuring the voltages produced, allowing technicians to verify that the transformer will function as intended when integrated into a larger electrical system. In practical applications, utilizing specialized devices from Globecore can enhance the accuracy of this test, facilitating precise diagnostics. Properly conducting the additive polarity test is essential to prevent phase issues and ensure the efficiency and safety of transformer operations, ultimately contributing to the effective testing of industrial oils, where electrical properties may be affected by transformer health.
