Transmission Line Loss Meter

摘要

Heretofore no acceptable method of metering transmission line losses has been established. The installation of metering facilities at each end of a line using the difference between input and energy output is inherently inaccurate because it requires using the difference between large quantities of similar magnitude, each of which may be in error. This report describes a method of metering transmission line losses from one end by using a loss meter. The principle of operation is to insert a miniature representation of the equivalent pi for the transmission line at one terminal, and by application of the proper voltage and current, the losses measured in the model are proportional to the losses in the line. This method of metering losses is particularly useful where the point of delivery and the metering equipment are at opposite ends of the line and where an adjustment in billing must be made to compensate for transmission losses. The loss meter method provides data useful in administering power contracts and agreements and system operation. (Author)
