The 150-kv. system operated for some years by the Southern California Edison Company has not made use of automatic operation of circuit breakers. The multiplication of generating stations and connections which accompanied the change to 220-kv. makes desirable the automatic sectionalizing of the line in cases of trouble and, therefore, requires circuit ...

CIRCUIT breaker application is being simplified. A subcommittee of the protective devices committee of the AIEE has studied methods of calculating short circuit currents and has prepared a report which presents a simplified procedure based on standardized contact parting times and typical current decrements.1 To facilitate the use of this method ...

Current can be transferred to the load of an inductive energy storage device by rapidly increasing the inductance of a circuit element connected in parallel with the load. The present paper suggests using a coil with a ferromagnetic core for this purpose. In addition to the principal (toroidal) field, an orthogonal (poloidal) control field is generated

Journal of the A.I.E.E., 1927
This paper tells of (1) conditions which govern the design of a breaker of a given interrupting capacity, (2) the standardization that has been accomplished in rating breakers, and (3) trends in the design of breakers constructed to meet operating requirements.

The vacuum circuit breaker has fascinated the switchgear designer for many years, primarily because of the great advantages of vacuum interrupters, which are: (a) They are entirely self contained, need no supplies of gases or liquids and emit no flame or gas.
