A structural diagram of the reference standard of ACR has been developed, the composition and technical requirements for its main elements have been determined. Functional wiring diagrams of reference measures of ACR have been compiled. The electric circuit diagrams of reference measures of ACR with nominal primary currents up to 1200 A and up to 5000 A have been developed. A working model of the ACR standard measure with nominal primary currents up to 1200 A has been manufactured. Methods for the investigation of ACR standard measures with the purpose of determining their metrological and operational characteristics have been developed. Comparative studies of the samples of two-stage current transformers have been carried out to determine the optimal design and technology for the production of standard ACR measures.
