The invention discloses electric power system power transmission and transformation safety equipment comprising a high voltage capacitor and a voltage dividing capacitor which are installed between the high voltage bus and the ground wire of a metering box and connected in series in turn, a signal processing unit, an A/D converter and an E/O conversion unit which are connected with a first power supply, and an O/E conversion unit, a display unit and a control unit which are connected with a second power supply. The control unit of the second power supply is also connected with a wireless remote control transmitter which is wirelessly connected with a wireless remote control receiver. Electrification of the input end of the high voltage metering box can be monitored in real time, the signal of electrification of the input end of the high voltage metering box can be transmitted to a light-emitting device or acoustic equipment, and then corresponding danger prompts can be performed according to setting of a control device.
