Frequency-modulated series resonant withstand voltage test equipment transformer induction withstand voltage test Note:

1. The power supply voltage is applied to the low-voltage winding, while the neutral point of the high-voltage winding remains ungrounded. The non-tested phase windings are shorted to ground to ensure safety and prevent unexpected voltage buildup. 2. If the transformer includes medium-voltage windings or balanced windings, it's important to ensure that their potentials are not left floating. All windings should be properly grounded or connected as required to avoid electrical hazards. 3. The test compensation capacitor is installed on the low-voltage side, and the voltage divider is located on the high-voltage side to accurately measure and control the test voltage during the procedure. 4. During the test, the test system and the equipment under test must be connected using a dedicated grounding wire provided for this purpose. This ensures proper grounding and minimizes the risk of electrical faults. For generator power frequency withstand voltage tests and when using variable frequency series resonant devices, it is essential to follow guidelines set by national and local power authorities. These tests are typically performed during manufacturing, installation, maintenance, operation, and preventive testing. The test voltage waveform and frequency should match those of the normal operating conditions. The standard test voltage is usually 0.75 times (2Un + 3000) volts or 1.5 times the rated voltage (Un), and the frequency is typically at the power frequency level. A suitable compensation capacitor is generally used to meet the AC withstand voltage requirements of the generator and ensure accurate test results. It's also crucial to monitor the test environment and maintain proper insulation to prevent any unexpected failures during the process.
