Abstract

PURPOSE: To detect line abnormality speedily, by monitoring the insulation resistance of AC neutral point of a runway illumination circuit.
CONSTITUTION: Constant current device 1 lights lamp L via transformer T connected to cable 2. Insulation diagnosis device 4 is connected to AC neutral point P of the load circuit, and insulation deterioration of cable 2 is monitored constantly. When the potential at point P is changed due to insulation deterioration, switch 5 operates and thus abnormality detection is performed.
