台。``As a technical standard for Kamekima equipment, low-voltage electric circuits are ``fi.''
It is stipulated that the insulation resistance value must be equal to or higher than a predetermined insulation resistance value depending on the L king. For this reason, conventionally, the quality of the insulation of a low-voltage line has been determined by cutting off the line each time and periodically measuring the insulation resistance to ground using a megger. In addition, the recently developed insulation monitoring device for electrical circuits is also available.

ff To explain in detail, the insulation monitoring device 1 has each responsibility 10. This device is installed in the changing room 11 and the home 9, and detects the insulation failure state of the electric circuit by utilizing the fact that a zero-sequence current flows when there is insulation failure. A multi-bundle transmission system that transmits an insulated state is a transmission unit 2. Receiving unit 3. Control unit 4)3
It consists of units. The transmitting unit 2 is the 1! when the insulation is defective in the insulation monitoring device 1! From the contact point Iba No. tP
Ti! It is a device that replaces the signal to be sent by I-line etc. (Receiving 4U unit)・3 is installed in a place where maintenance personnel are permanently stationed, and receives the transmitted signal on a one-to-one basis. The control unit 4 is a unit for sending reports to the central monitoring inn 16, and the control unit 4 is a unit that controls the entire transmission unit.
