FAQ
Q: How long does a typical test take for six samples?
A: A complete test for six samples including 6 breakdown tests each, stirring and standing takes approximately 15~20 minutes total. This is the same time as testing one sample on a single-cup tester, making GDOT-6B six times more efficient for high-volume testing.
Q: Can it test different types of oil samples simultaneously?
A: Yes. Each of the six test cups is independent. You can test different types of oil samples (e.g., transformer oil, switch oil, capacitor oil) or different batches of the same oil simultaneously. There is no cross-contamination between cups as each uses a dedicated electrode system.
Q: What safety measures are in place to protect operators?
A: GDOT-6B is equipped with a comprehensive safety protection system:
- Door interlock: Automatically cuts off high-voltage output when the test chamber door is opened
- Automatic discharge: Automatically discharges residual voltage after test completion
- Multiple electrical protections: Over-voltage, over-current, over-load and short-circuit protection
- Emergency stop button: One-button emergency stop for any abnormal situation
- Fully enclosed high-voltage chamber: Prevents accidental contact with high-voltage parts
