METER OF METROLOGICAL CHARACTERISTICS OF CURRENT TRANSFORMER Russian patent published in 2004 - IPC

FIELD: electrical engineering. SUBSTANCE: meter is intended for remote measurement of metrological characteristics of tested current transformers in single- and three-phase high-voltage networks at sites of their operation. Characteristic feature of invention consist in use of small-size precision current transformer for measurement of reaction of tested current transformer to action of test current, in application of original algorithm for processing measurement results and in remote control over test process. EFFECT: provision for remote control over process of measurement of metrological characteristics of current transformers at sites of their operation, for raised sensitivity and accuracy of measurement and for reduced cost, mass and overall dimensions of meter. 1 cl, 1 dwg
