TEST-MANAGING EQUIPMENT FOR POWER SYSTEM MONITOR AND CONTROLLER, AND RECORDING MEDIUM WITH PROGRAM RECORDED THEREOF

PROBLEM TO BE SOLVED: To eliminate writing of program in a medium, transportation of the medium, and installation of software from the medium, when conducting factory tests after shipment or on-site tests after a Revision (updating). SOLUTION: A network system is constituted of at least one power system monitor and a controller and which monitors and controls a power system and records and stores power information and a test managing equipment connected to the power system monitor and controller via a network. In this case, the functions of the test managing equipment 101 of a version which has been updated compared to those of the power system monitor and controller 1 (1-1,...) or functions, which are provided in the test managing equipment 101 but not in the power system monitor and controller, are transmitted from the test managing equipment 101 to the power system monitor and controller and then executed on the power system monitor and controller.
