Electric incoming signal assessing device and electric power distribution facility having same

The utility model discloses an electric incoming signal assessing device and an electric power distribution facility having the same and relates to the electric incoming signal assessing device. The electric incoming signal assessing device is provided with a plurality of passageways. Each passageway comprises an input end for receiving an electric incoming signal and a signal processing device. The signal processing device is used for generating a pulsated electric signal having at least one pulse from the incoming signal or from a signal led out from the incoming signal. The width of the at least one pulse depends on the voltage amplitude of the incoming signal. The device has a common microprocessor which is used for receiving the pulsated signal of each passageway or a signal led out from the pulsated signal, a numerical value is generated through assessment of respective pulse width of each received signal, and the numerical value corresponds to the voltage amplitude of the incoming signal of a correspon
