1. Core functions
The fully automatic anti-interference dielectric loss tester is mainly used to measure the dielectric loss tangent (tg δ) and capacitance (Cx) of high-voltage electrical equipment. By evaluating the loss characteristics of insulation materials, the insulation status of the equipment can be determined, and faults caused by insulation aging or defects can be prevented. Its core advantage lies in fully automatic measurement and strong anti-interference ability, suitable for scenarios such as substations, power plants, laboratories, etc.
2. Technical features
① Anti interference design
Frequency conversion anti-interference technology: By using multi frequency test signals of 45Hz/50Hz/55Hz, it avoids power frequency interference and improves measurement accuracy.
Vector operation method and phase shifting method: automatically track and cancel external electromagnetic interference to ensure data stability.
Shielding structure and grounding protection: The test line is equipped with a built-in shielding layer, and the instrument has functions such as high voltage protection and CVT self-excited protection to prevent equipment damage caused by misoperation.
② High precision and wide range
The dielectric loss resolution reaches 0.01%, and the capacitance measurement range covers 1pF~10000pF, meeting the testing needs from low-voltage equipment to ultra-high voltage transformers.
③ Intelligent operation
One click fully automatic measurement: without manual intervention, the instrument automatically completes voltage boosting, data acquisition, and analysis.
Chinese menu and printing function: supports direct reading of results, data printing, and RS232 interface export for easy recording and traceability.
3. Typical application scenarios
① Power system: insulation performance testing of high-voltage equipment such as transformers, transformers, bushings, capacitors, etc.
② Electrical equipment manufacturing: quality inspection and aging test before leaving the factory.
③ Research and Testing: Performance Study of Insulation Materials, Development and Verification of New Equipment.
4. Summary of Advantages
① Efficiency: Fully automated processes shorten testing time and improve work efficiency.
② Reliability: Anti interference technology ensures data accuracy in complex electromagnetic environments.
③ Security: Multiple protection mechanisms ensure the safety of operators and equipment.
5. Precautions for use
