Four-parameter transient recovery voltage circuits appropriate for testing of extra high voltage circuit breakers

Economical four-parameter transient-recovery-voltage (TRV) circuits for testing high-power circuit breakers have been obtained. The principles of four-parameter TRV-producing phenomena are introduced, and preliminary experiments to confirm these principles are reported. Calculations for simulation of current interruption taking into account arc voltages and parallel capacitances of circuit breakers are presented. The calculations show good agreement with experimental results.<
