DEVICE TESTING ELECTRIC STRENGTH OF INSULATION Russian patent published in 1997 - IPC

Abstract RU 2076331 C1

FIELD: electrical engineering. SUBSTANCE: parallel connection of high-resistance resistor 4 and ammeter 5 to low-resistance resistor 6 and capacitor 7 linked in series results in that current of puncture maintenance is much smaller than current of puncture formation and power consumed from source of testing voltage will be much smaller than power necessary for puncture fixation in presence of only one resistor. EFFECT: increased operational reliability. 1 dwg
