Product Introduction
TLHG-203transformer comprehensive test bench can truly determine the no-load current, no-load loss, impedance voltage and load loss of power transformers, accurately measure the DC resistance and transformation ratio of power transformers, implement condition diagnosis, ensure safe operation, and provide reliable data for monitoring or repairing transformers. The transformer comprehensive test bench is suitable for power supply and distribution systems, power transformer manufacturers, industrial and mining enterprises and other units.
Product Features:
1. Transformer no-load, load, DC resistance, transformation ratio and polarity tests.
◇ The transformer no-load, load, DC resistance, transformation ratio and polarity tests are completed through the industrial computer.
◇ The transformer comprehensive test bench conducts comprehensive control and measurement monitoring of the entire circuit.
◇ The measured data is automatically processed by the microcomputer, and can be stored and printed as needed.
2. Power frequency withstand voltage test
◇ Since this test is a safety high-voltage test, in order to ensure the safety of test equipment and personnel, this test does not use the industrial computer to complete the test.
