摘要：
It is shown that the betel resistor shunting equipment enables the nominal disconnection current of the VVN series air-blast circuit breakers, operating at a voltage of 110 - 330 kV and a current of up to 31.5 kA, to be increased. The upgraded circuit breakers satisfy the requirements of the Russian Federation standards. Values of the resistance of the resistors and methods of mounting them are presented, and also measures which must be taken to upgrade all types of circuit breakers. © 2012 Springer Science+Business Media, Inc.
