Single phase power table can be directly used to measure for single phase alternating current circuit; Measurement of power for three-phase circuit mainly contains three kinds of methods: one watt of method, two watts of methods and three watts of methods. One watt of method can only be used for the measurement of power of three-phase symmetrical circuit, it may also be useful to the power of any phase measured by a single phase power table, then it is multiplied by the total power that namely 3 obtain three-phase load; Two watts of methods may be used for three-phase symmetrical circuit and the measurement of power of asymmetric three-phase three-wire circuit, and total power equals the algebraic sum of two single phase power table readings; Three watts of methods are mainly used in the measurement of power of asymmetric three-phase four-line system, and the total power of three-phase load equals the reading sum of three single power meters.
Usually electric energy table is used the energy consumption of escalator and man conveyor belt to be measured, but conventional electric energy table cannot realize the reverse record of electric energy and calculating. Along with the application of energy back feed device technology on escalator and man conveyor belt, electric energy not only drawn by escalator and man conveyor belt from electrical network, and can to electrical network feedback power, so conventional electric energy table cannot realize the Measurement accuracy to elevator operation energy consumption.
