<p>PURPOSE: To protect an electrical facility in real time by providing a turbulence current display at a current connection part in a facility with a common ground line and a current supply element having a current connection part for transmitting signals. CONSTITUTION: Current supply components (a) and (b) are connected to a common ground point Mp by conductors Ea and Eb and are connected at a current connection part S for transmitting signals. A turbulence current display K is provided in the connection part S to detect a turbulence current Is. The components (a) and (b) and capacitors Ca and Cb are connected to the ground to filter Is. An Is display K has a sensor and a signal generator SG. The sensor has a ferromagnetic core RK with a coil winding W that can be inserted into the connection part S, and the coil winding W can operate on the signal generator SG via a control device GE. With this configuration, when a turbulence signal Is exceeding a specific level is generated while an electrical facility is operating, a signal can be generated immediately.</p> |
