Abstract:
A portable power measurement system for calculating the power flow within at least one wire to a revenue meter of a customer and transmitting an indication of said power flow to a remotely located operator comprising:(a) a current transformer that senses current within said wire at a location remote from said revenue meter and generates a first output signal;(b) a voltage input that senses voltage within said wire at a location remote from said revenue meter and generates a second output signal;(c) a polarity comparator that compares the polarity of said first signal with the polarity of said second signal and generates in response a polarity status signal;(d) a measurement device that receives said first output signal, said second output signal and said polarity status signal and in response generates a third signal representative of said power flow within said wire;(e) said measurement device includes a speech encoding circuit that receives said third signal and in response generates a voice signal;(f) said measurement device includes a cellular telephone transmitter that receives said voice signal and transmits said voice signal through the air, and said voice signal is received by said remotely located operator; and(g) said current transformer, said voltage input, said polarity comparator and said measurement device being housed in a single portable unit for installation at any one of a plurality of locations along said wire.
