FAQ
Q: How does the high-frequency induction heating work?
A: High-frequency induction heating uses electromagnetic induction to generate eddy currents in the metal oil cup, heating the oil sample directly from the inside. This provides uniform heating throughout the oil sample with no temperature gradients, no local overheating, and faster heating speed compared to traditional resistance heating.
Q: How often does the standard capacitor need to be calibrated?
A: The GD6100 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. GD6100 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 room temperature to 100℃, covering all standard test temperatures required by international standards.
