Abstract

1,105,368. Coil testing. BROWN, BOVERI & CO. Ltd. Dec. 22, 1965 [Dec. 24, 1964], No.54296/65. Heading G1U. In order to provide adequate protection against glow discharge when testing bar conductors and coils of electrical machines, the conductor is provided with a semi-conductor layer to which is temporarily connected a network of resistors or capacitors which modify the potential distribution along it.
