Abstract

The steady-state error is the most important parameter for the calibration system of electronic transformer

and it ensures to practice in power system.According to correlative national standards the steady-state error calibration technical was discussed

and the relative suitable calibration circuit was designed based on the secondary output mode of different transformer.In order to solve problems

the error component of each section is analyzed

and a feasible method was presented

which combined with the new designed electronic transformer steady-state error calibrator

then the calibration system was established.The experiment result indicates that the calibration system has achieved the requests in the field of measurement and operation stability.
