In each switchboard, in order to supply the high voltage high current to the facilities in each facility, each equipment and the switchboard are usually connected by a bus-bar, and a reduced AC voltage is supplied to the equipment through the busbar.

On the other hand, the switchboard is vulnerable to theft and electric accidents due to the economic recession. Especially, in order to improve the efficiency and stability of power use, which is rapidly increasing in power consumption, it is necessary to monitor the condition of the switchboard. It is difficult to grasp the electric power flowing at the one glance, so that it is difficult to check the deterioration state of each of the gauges and determine the abnormality of each gauges during the electric power supply as well as the power failure accident and other safety accident rate.

In recent years, the power monitoring system (HMI system) is used to monitor the flow of electric power, but it is not only expensive equipment, but also requires a lot of management personnel. In particular, irrigation and civilian companies are unlikely to introduce this system If there is a problem in the switchboard, it is difficult to solve the problem that arises if there is no person in charge.
