METHOD FOR OVERVOLTAGE LIMITATION IN ELECTRIC NETWORKS

摘要

FIELD: electricity. ^ SUBSTANCE: method consists in three condensers star-connection to network phases. Condenser common point is grounded via resistor and reactance connected in parallel. In this case condenser, resistor and reactance parameters are selected from condition of arc extinction insuring when forced closing current is crossing zero, that provides the least multiplicities of overvoltage. ^ EFFECT: electric network reliability and safety improvement. ^ 3 dwg, 1 tbl
