FAQ
Q: What is the system background noise of GDYT-10/100?
A: The system adopts an all-system PD-free design. The partial discharge of each component is strictly controlled: test transformer <1pC, coupling capacitor <0.5pC, protective resistor <0.3pC. The total system background noise is <2pC at rated voltage, which meets the IEC 60270 basic test requirements for distribution equipment.
Q: Does it require three-phase power supply?
A: No. GDYT-10/100 adopts 220V single-phase input design, which can be used in any ordinary workshop or on-site location without three-phase power supply. This greatly expands its scope of application and reduces the requirements for test environment.
