The invention discloses an efficiency monitoring and analysis instrument for an electric device. The efficiency monitoring and analysis instrument is directly connected in series in the power supply circuit of the electric device. The instrument comprises an acquisition module, a monitoring and analysis module and a communication module. The acquisition module is used for acquiring the electricalparameters of the electric device and sending the electrical parameters to the monitoring and analysis module. The electrical parameters comprise voltage and current. The monitoring and analysis module is used to analyze and process the acquired electrical parameters to acquire the status and duration of the electric device, calculate the power consumption and accumulated power of the electric device in each phase according to the power and duration of the electric device in each status phase, and judge whether the device has an over-current or over-voltage fault. The communication module is used to communicate with a server through an accessed network interface, and send the calculated device parameters and fault determination result of the monitoring and analysis module to the server.
