ABSTRACT:
The factors affecting the operational reliability of primary measuring transducers (PMT) developed on the basis of ferromagnetic current transducers with adjustable range (FMCT RD) are highlighted. An assessment and analysis of the system of basic quantitative indicators of reliability for each of the proposed three current converters, which differ in the principles of operation and the number of assembly units, is made. A maintenance and repair strategy is indicated, combined with the use of methods and tools of a modern diagnostic system that ensures the reliability of these converters, using a combination of three groups of stages: during design, during their operation and repair.
KEYWORDS:ferromagnetic current converters, operational reliability, assessment of point indicators of reliability, gamma resource, diagnostics, maintenance and repair strategy.
