Power transformer testing is conducted using various methods to assess the transformer’s performance, insulation, and overall health. The process typically includes open circuit testing of transformer, which involves energizing the transformer on the primary side while the secondary side remains open. This method helps in measuring the voltage, current, and power input, providing critical information about the transformer’s impedance, efficiency, and winding condition. Additionally, insulation resistance tests, power factor testing, and thermal imaging can be utilized to evaluate the transformer’s integrity and predict maintenance needs. Using dedicated testers such as those from Globecore can enhance the accuracy and reliability of these assessments.
