A novel and improved control and supervisory system for power distribution equipment including a plurality of terminal control and/or supervisory devices each capable of controlling and/or supervising a plurality of power distribution devices in an extremely simple, high-speed and efficient manner without requiring any central control and/or supervisory unit. To such control and/or supervisory operation, no vast and full knowledge of permitted and inhibited operations of varying kinds of power distribution devices connected therewith, as well as of the control and supervisory procedures therefor, is required. To these ends, each of the terminal control devices comprises a control and/or supervisory instruction section operable to output a control or supervisory command for controlling or supervising a plurality of power distribution devices, and a control and/or supervisory section operable to receive the control or supervisory command from the control and/or supervisory instruction section for generating a control or supervisory signal suited to control or supervise a corresponding one of the power distribution devices, and outputting it to the corresponding power distribution device. In one embodiment, the control or supervisory command is conceptually common to the power distribution devices. In another embodiment, the control and supervisory command is intrinsic to a corresponding one of the power distribution devices. Thus, there is no need for a sender terminal device to prepare specific control and supervisory programs suited to the respective power distribution devices.
