Abstract

Measurements were described as current, voltage, and local dielectric strength for a current interrupter which utilized a novel form of electromagnetically convolved electric arc in air. Experiments have been performed with various interrupter structures and operational conditions. Precurrent zero-voltage extinction peaks and post-arc local breakdown voltages have been measured and are compared with values for nonconvoluted arcs in nitrogen and SF<inf>6</inf>. An empirical relationship between the extinction peak voltage and various design and operational parameters is presented. Signatures for the various interrupter structures under different operational conditions have been obtained by using a chromatic methodology and embodying the extinction peak and a local breakdown voltage. © 2009 IEEE.
