PURPOSE:To separate a body from a setting and control part in a protective relay testing device, facilitate the carrying of the setting and control part, shorten the test time, and reduce the carriage of heavy cargos. CONSTITUTION:The body of a test voltage and current supplying part occupying the greater part of the weight of a protective relay testing device is separated from the setting and control part of a test element, and they are connected to each other by wire or wireless, or through an optical circuit. Thus, the setting and control of the test element and the connection change of a test terminal can be carried out by a single testing worker required. |
