Measurement Deviation Test and Power Compensation Caused by Unqualified Transformer Configuration
Transformer is an important part of electric energy metering device,whose unqualified configuration can produce measurement deviation.For the transformers with unqualified configuration in accuracy and secondary load,this paper emphasizes the viewpoint of power measurement deviation,suggests the composite measurement error under the real load as the basis of power compensation,and discusses the specific methods for measurement calculation and power compensation.In view of the difficulties in composite error measurement and calculation,it probes into the calculation methods for the average load current and the error linear deduction for average load current.Then the Real Circuit Access Method for real load error test is proposed and compared with the conventional Run The Test Method.
