Post-fault Electricity Analysis and Compensation Method for Three-phase Three-wire High-voltage Meters
Methods for compensating electricity consumption are inconsistent and inadequate in evaluating compensation deviations when measuring faults in three-phase electricity meters.In view of this,the present work carried out an in-depth analysis of correction coefficients for various incorrect wiring of metering devices through examples,and proposed a new alternative calculation method based on electricity meter data during faults in the case of three-phase load balance.Fi-nally deviations of different electricity compensation methods was demonstrated through simulation and on-site examples,and it was concluded that under the condition of three-phase load balance,with respect to three-phase three-wire meter,the accuracy of using substitution method is higher in calculating active energy of abnormal measuring device.
