Abstract:
An electrical power distribution monitoring system, for a power distribution line having a plurality of sections with a plurality of electrical loads connected to the power distribution line to form a power distribution network and having a power input at an input end, there being a plurality of electrical loads connected to the power distribution line to form a power distribution network, said monitoring system comprising:(a) at least one first power sensor means arranged to measure power being supplied to said power distribution line at said input end;(b) at least one second power sensor means arranged to measure power passing between said power distribution line and at least one specific one of said electrical loads;(c) a data store containing data relating to past power consumption of said plurality of sections set in advance by electrical loads connected to said power distribution line;(d) calculating means arranged to estimate electrical values for at least one said section of said power distribution line in dependence on present electrical values measured by said first power sensor and said second power sensor and said data in said data store; and(e) distribution lines between said at least one first power sensor means and said calculating means, or between said at least one second power sensor means and said calculating means, used as a medium of a control signal.
