EMPU is an intelligent and multifunctional enclosed busbar monitoring system applied to power systems. It can not only monitor the voltage difference, impedance, and temperature of enclosed busbars, but also be directly used as an electrical parameter measuring instrument to measure electrical parameters such as current, voltage, power, harmonics, etc. It has functions such as electricity accumulation, wire system selection, fault recording, over limit alarm, temperature gradient, and historical data query. It can monitor 4 passive switch signals simultaneously. EMPU has 2 relay outputs, which can not only achieve remote control, but also associate voltage difference, voltage, current, residual current, frequency, power factor, and temperature to achieve alarm control.

The eMPU enclosed busbar monitoring system consists of the eMPU-M enclosed busbar monitoring device, the eMPU-H enclosed busbar temperature collection module, and the eMPU-T enclosed busbar temperature sensor. The eMPU-M enclosed busbar monitoring device can be equipped with 16 eMPU-H enclosed busbar temperature collection modules. Each eMPU-H enclosed busbar temperature collection module can be connected to 8 eMPU-T enclosed busbar temperature sensors. The MPU-M enclosed busbar monitoring device is connected to the eMPU-H enclosed busbar temperature collection module through TC-BUS-PDC bus communication, which can achieve remote temperature collection up to 240 meters long.
