ull phase-phase voltage of the circuit. In Oscillograms A and B it will be noted that the static discharge occur-red on the descending wave; the maximum current impulse is relatively lowand, as seen, is extinguished by the arrester in very short time intervals. InOscillogram C the discharge… … Oscillogram B Arrester—Type EX, Form 3, rated for 2500 Volt 3 phase grounded Y circuit.Test Voltage—3000.Dynamic current flow—8.0 amperes.Duration of current flow—.22 cycle or .0036 second.
