FAQ
Q: What types of high voltage switches can GDKC-15D test?
A: GDKC-15D can test almost all types of high voltage switches:
- Vacuum circuit breakers: 10kV ~ 40.5kV indoor and outdoor vacuum circuit breakers
- SF6 circuit breakers: 110kV ~ 1000kV SF6 circuit breakers and GIS combined electrical appliances
- Oil-minimum circuit breakers: Traditional oil-minimum circuit breakers
- Other switches: Disconnecting switches, grounding switches, load switches, reclosers and sectionalisers
It supports various test modes including single opening, single closing, open-close, close-open and open-close-open reclose sequences.
Q: What is the advantage of integrated loop resistance test compared to separate testers?
A: Traditional circuit breaker testing requires two separate instruments: a mechanical characteristic tester and a loop resistance tester. GDKC-15D integrates both functions into one device, providing the following advantages:
- Reduced test time: No need to change wiring between different tests, completing all tests with one wiring
- Lower cost: One instrument replaces two, reducing equipment purchase cost
- Improved portability: Less equipment to carry, more convenient for on-site testing
- Unified data management: All test data is stored in one device, facilitating unified management and report generation
Q: How does the double-end grounding test function work?
A: Double-end grounding test is a special test mode required for high voltage circuit breakers in substations where both sides of the breaker are grounded for safety. GDKC-15D adopts advanced isolated acquisition technology that can accurately measure the opening/closing time and synchronization of circuit breakers under double-end grounding conditions, eliminating the influence of ground potential difference. This function is essential for safe on-site testing in substations.
Q: Can it test graphite contact circuit breakers?
A: Yes. GDKC-15D has a dedicated graphite contact test mode. Graphite contacts have different electrical characteristics from metal contacts, and traditional test methods often produce inaccurate results. The dedicated graphite contact test mode of GDKC-15D uses special signal processing algorithms to accurately measure the opening/closing time and bounce characteristics of graphite contact circuit breakers.
Q: How to calibrate the instrument?
A: GDKC-15D can be calibrated using standard time generators, standard resistors and standard force gauges with accuracy not lower than 0.2 class. The calibration procedure is simple and fast:
- Enter the calibration mode in the instrument menu
- Follow the prompts to connect the standard equipment
- Complete the calibration of each parameter (time, resistance, velocity, travel)
- The instrument will automatically save the calibration coefficients
The instrument should be calibrated once every 12 months according to national metrology requirements.
