Title: Electric meter
Inventor: NAGURA HIDETOSHI
IPC: G01R19/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To achieve an accurate measurement even if an inexpensive current transformer is used by performing a specified operation and error compensation based on the output of an A/D converter. SOLUTION: The phase error correction is performed by correctingly operating the measurement value of a secondary current effective value of a current transformer CT with the approximate expression of a phase error obtained by estimation, in principle. The influence of the phase error can be reduced by this principle. Input current and voltage where the phases of corrected signal sources GOS1 and GOS2 are synchronized are taken into an electrical measuring instrument METER. A phase value between the current and voltage of the non-corrected signal sources GOS1 and GOS2 output is measured and is read by a computer PC. While PC control changes the output current of the signal source GOS1, measurements are repeated by the METER. The PC estimates the approximate expression and the correction operation expression of a phase error from input and measurement values.  The approximate expression and the correction operation expression are described in a program for PMC at a signal-processing stage and are written into a memory PROM. After these operations, a correction operation is made to the non-corrected measurement values and corrected measurement values are outputted from the METER.
