PURPOSE:To accurately and easily recognize the supplying state of each system, supplying extent of a designated system, operating state, etc., of system equipment installed to the systems, etc., even when a plurality of systems are simultaneously designated. CONSTITUTION:A connected state storing section 1 stores in advance the connected state of each power supply system and a first detecting section 2a detects the supplying state (power failures, charging, inspections), etc., of each designated power supply system. At the same time, another first detecting section 2b detects the operating state of system equipment (for example, a circuit breaker) installed to each power supply system which is the object to be detected of the section 2a. A second detecting section 3 discriminates the supplying extent of each power supply system by using the sections 1, 2a and 2b and a displaying section 4b displays the supplying state of each system on a CRT 5 by using predesignated displaying colors. |
