METHOD FOR MEASURING OF STEADY-STATE RESISTANCE OF INSULATION Russian patent published in 1998 - IPC

Abstract RU 2101716 C1

FIELD: electric engineering instruments, in particular, testing insulation of heavy current electric machines with large time constant. SUBSTANCE: method involves measurement of resistance value, its first and second derivatives and calculation of steady-state resistance as double resistance value at moment when first derivative is maximal and second derivative is equal to zero. EFFECT: decreased time for measurement of steady- state value of insulation resistance. 1 dwg
