Measurement methods for instantaneous switching instruments

Abstract:

This paper summarizes the relay twitter test in details，and explains the function of instantaneous switching instrument during this test. On the basis of analyzing the working principle and wave collection process of instantaneous switching instrument, the change law of on-off action for relay contact is concluded. The method simulating the action of relay in measuring instantaneous switching instrument is proposed. A set of general instrument for measuring these kinds of devices is established.
