Term definition

1. Opening (closing) time: The opening (closing) wire coil is powered on as the starting point for timing, until the time when the moving and stationary contacts just open (close).
2. Same phase and same period: The difference between the opening (closing) time and the closing time within the same phase.
3. Phase to phase synchronization: The difference between the opening (closing) time of a three-phase system.
4. Average speed: During the opening (closing) process, 10% of the total travel of the moving contact is removed from the front and back, and the middle 80% is taken. The ratio of the travel of the moving contact to time is calculated.
5. High speed: During the opening (closing) process, after the moving contact starts to move, the moving contact moves every 10ms as a speed unit until the moving contact stops, and several speed unit values are obtained, among which the larger unit speed value is the opening (closing) high speed.
6. Rigid opening (closing) speed: Depending on the manufacturer of the tested switch and the switch model, each manufacturer has defined different rigid opening and closing speeds. This tester includes various definitions for users to choose from. （Shanghai High Voltage Switch Characteristics Tester Manufacturer）
