1. Working principle: The partial discharge tester determines whether the insulation status is normal by detecting the partial discharge signal in the equipment or material. It uses high-frequency sensors or probes to convert partial discharge signals occurring in equipment or materials into measurable electrical signals.
2. Application field: Partial discharge testers are widely used for insulation status detection and fault diagnosis of various electrical equipment such as power systems, insulation materials, transformers, generators, switchgear, etc.
3. Measurement parameters: The partial discharge tester can measure and record the discharge quantity, discharge duration, discharge frequency, and other parameters of partial discharge. These parameters can be used to evaluate the insulation status of equipment or materials and determine whether there is an insulation fault.
4. Fault diagnosis: By analyzing the data collected by the partial discharge tester, insulation faults in equipment or materials can be identified and located. This helps to identify potential fault points in advance and take corresponding repair or replacement measures.
5. Standards and specifications: The use of partial discharge testers usually follows relevant international standards and specifications, such as the IEC 60270 standard of the International Electrotechnical Commission (IEC).
6. Maintenance and upkeep: In order to ensure the accuracy and reliability of the partial discharge tester, it is necessary to calibrate and maintain it regularly. In addition, correct operation and maintenance of testing instruments are also key to ensuring the accuracy of test results.
7. Safety precautions: When using a partial discharge tester, electrical safety regulations should be followed and attention should be paid to preventing electric shock or other safety risks. At the same time, it is necessary to understand and comply with the instructions and relevant operating guidelines for testing instruments.
