发明名称 REFERENCE METER OF HEAVY DIRECT CURRENTS
摘要 FIELD: electrical engineering, specifically, tests of stationary measurement systems for currents exceeding 100 kA without their dismantling. SUBSTANCE: it is suggested that digital integrator based on converter of analog voltage to number of pulses with use of pulse-duration modulation should be used to expand functional capabilities to raising limit of measured currents and to diminish measurement errors. EFFECT: increased integration speed, improved technical characteristics of entire meter. 1 cl, 3 dwg
