METHOD OF MEASUREMENT OF HIGH VOLTAGE OF DIRECT CURRENT Russian patent published in 1997 - IPC

FIELD: radio measurement technology. SUBSTANCE: method is meant for effective measurement of direct voltages in high-voltage circuits. Proposed method consists in action with high voltage on high-voltage arm of capacitive divider. Electric signal from low-voltage arm of capacitive divider is commutated, amplified and recorded. Time of break is chosen from condition of full charge of capacitive divider and time of closure - from condition of complete discharge of low- voltage arm of capacitive divider. Device for realization of method includes high-voltage source 1, capacitive divider 2, electron commutator 3, amplifier 4 and measurement unit 5. EFFECT: improved reliability of method. 1 dwg
