Function of the HMYDJC Cascade Oil-immersed Test Transformer
The HMYDJC cascade oil-immersed test transformer is a device specifically designed for high-voltage testing, with primary functions including:
Insulation Withstand Voltage Testing:
Conducting insulation withstand voltage tests on electrical equipment (such as cables, motors, generators, transformers, etc.) to verify whether their insulation performance under high voltage meets standard requirements.
This testing aids in identifying potential insulation defects, ensuring the safety and reliability of equipment during actual operation.
Partial Discharge Testing:
Detecting whether partial discharge phenomena exist in electrical equipment under high voltage conditions. This assists in evaluating the insulation status and degree of ageing of the equipment.
Partial discharge testing is a crucial means of preventive maintenance, enabling the early detection and resolution of potential issues.
Dielectric Loss Tangent Measurement:
Measures the dielectric loss tangent (tanδ) of equipment at specific frequencies to evaluate the quality and ageing of insulating materials.This test aids in determining the insulation condition and predicting the service life of equipment.
Other Electrical Performance Tests:
Provides high-voltage output for various electrical performance tests, such as breakdown voltage testing and leakage current testing.
Suitable for diverse high-voltage testing requirements in both laboratory and field settings.
