POWER DISTRIBUTION SYSTEM CONTROLLER

PURPOSE:To delicately monitor a power distribution system control by measuring present current values of respective power distribution systems divided into a plurality at a predetermined period, comparing them with a reference value at another predetermined period indicated on a CRT screen, and further measuring in a special power distribution system at another period. CONSTITUTION:A power distribution system controller 1 is connected to a plurality of distribution lines and a bank (one system in the drawing) for constituting a power distribution system, a value measured by an ammeter 3 is periodically stored in a memory 8 through overload detecting means 4, and displayed on a CRT 5 through screen indicating means 6. The measured value 3 is compared with a reference value at another period, an alarm is given from an alarm unit 12 at the time of a malfunction, printed by a printer 11, and a lamp 13 is lit. Overload detecting means 4, image indicating means 6 and the CRT 5 are operated by inputting a signal from an operation desk 14 at a shorter period than the previous period. Thus, monitoring and overload detecting when a variation in a load is predicted can be carefully performed.
