Abstract
This work presents an analytical study of the several phenomena associated with interrupting light capacitive currents in air with disconnecting switches. The computer work is based upon and duplicates observed field performance of EHV disconnects operating at 400 kV and 505 kV. Particular attention is given to magnitudes of current and voltage surges produced as a function of bus megavoltamperes, switch resistance, and capacitance load. Simplified equivalent circuits and concepts are introduced to permlit easy analysis of EHV switching problems.
