Abstract

See full text

A method for measuring at least one electrical parameter of the operation of a p-phase power line, p being a positive integer, arranges respective sensing apparatus to sense at least one of the voltages and currents associated with each phase of the power line. Analog-to-digital conversion apparatus is used to digitize the response of each sensing apparatus, thereby to generate corresponding digital responses. A digital computer is used to correct each digitized response of the analog-to-digital conversion apparatus for non-linearities, gain errors and phasing errors in the responses of the sensing apparatus and for non-linearities and gain errors in the responses of the analog-to-digital conversion apparatus. The computer is used to high-pass digitally filter each digital response that has been corrected, in order to suppress any attendant direct term. The digital computer then calculates each the electrical parameter, proceeding from each digital response that has been corrected and has been high-pass digitally filtered.
