FAQ
Q: What is the advantage of high-frequency induction heating compared to traditional resistance heating?
A:
- Uniformity: High-frequency induction heating heats the entire oil cup uniformly, resulting in a temperature difference of less than 0.5℃ in the oil sample
- Speed: Reaches 90℃ from room temperature in less than 20 minutes, 3 times faster than traditional resistance heating
- Safety: Non-contact heating, no open flame, no risk of overheating and fire
- Accuracy: No local overheating, prevents thermal degradation of oil samples, ensures accurate test results
Q: How often does the standard capacitor need to be calibrated?
A: The GD6100H uses an SF6 gas-filled three-electrode standard capacitor with a dielectric loss of less than 0.0001. Its performance is extremely stable and unaffected by ambient temperature and humidity. Under normal use, it only needs to be calibrated once every 2 years according to national metrology requirements.
Q: Can it test different types of insulating oils?
A: Yes. GD6100H can test all types of liquid insulating materials including transformer oil, switch oil, capacitor oil, cable oil and synthetic insulating oils. It supports test temperatures from 40℃ to 120℃, covering all standard test temperatures required by international standards.
Q: Does it require manual oil discharge after testing?
A: No. GD6100H has a built-in automatic oil discharge system. After the test is completed, the instrument will automatically discharge the test oil into the waste oil container. No manual oil pouring is required, making the operation clean and safe.
