Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] The measurement of the response time of the protection system mainly measures the response time of each protection system logic. For the response time test of each logic, it is necessary to access the trigger of an input signal of this logic as the reference point for the start of time record acquisition, and then select the output signal of this logic as the reference point for the end of time record acquisition.
[0040] The entire measurement process is mainly divided into two parts: signal switching and measurement time.
[0041] Signal switching: It takes about 10 to 30 minutes, depending on the number of switching signals and the difficulty of disconnecting the cabinets.
[0042] Measuring time: about 1 to 2 minutes, used for multiple signal triggering, recovery and recorder data recording.
[0043] From the above empir...
