Input technical indicators detection of communication system
What are the test contents for communication input
(1) Select one or more AC signal input terminals of the device in the compartment layer and apply AC analog signals.
; (AC voltage, AC current). (2) Set corresponding limit crossing and compound values at the station control layer and activate alarms. (3) Change the output value of the simulation device and meet the conditions for exceeding or repeating the limit. Check the alarm screen, print records, and display screen at the station control layer to see if they are consistent with the simulation actions and values. (4) Perform voltage, current, active, reactive power, frequency over upper and lower limit alarm function tests and restore upper and lower limit alarm function test records in sequence; The data of AC telemetry input values during self recovery, power on and power off processes, dual machine and network switching processes shall not undergo jump testingFunction of testing report:
