3-phase transformer testing is performed by using specialized equipment that measures various parameters, such as insulation resistance, winding resistances, and turns ratios. First, insulation resistance is measured using a megohmmeter to ensure that the transformer insulation is intact. Next, winding resistances are checked using a low-resistance ohmmeter to identify any potential issues in the windings. Turns ratio tests are conducted using a transformer turns ratio tester to ensure that the transformer is performing according to specifications. Additionally, power factor testing can be carried out to assess the quality of the insulation in the transformer. It’s essential to follow safety protocols and manufacturer guidelines during testing to ensure reliable results and prevent damage to the equipment. Globecore offers a range of testers and devices specifically designed for comprehensive 3-phase transformer testing, ensuring accuracy and reliability in diagnostics.
