Document Type and Number:
Japanese Patent JP6698471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the installation work cost of a distributed power source.SOLUTION: A construction method of a power system according to an embodiment of the present invention utilizes a 100-V single-phase two-wire distributed power source 14. In this method, the 100-V single-phase two-wire distributed power source 14 is connected to an R-N phase in a single-phase three-wire power system via a ground-fault interrupter 12 so as to construct a power system S1 comprising the ground-fault interrupter 12 and the distributed power source 14. A regular ground-fault interrupter, which is not equipped with a cut-off switch to cut off electric conduction to a trip coil for switching a main contact from an on-state to an off-state, is used as the ground-fault interrupter 12 instead of a reversely-connectable ground-fault interrupter.SELECTED DRAWING: Figure 1
