IGCT1 and the eight diodes to the right of D1-D4 comprise the solid state switches for the
remaining two phases. The programmable controller sits between the data acquisition laptop
computer and the automation laptop computer.

B.3 Switching Stresses
Before any momentary service interruption testing began, the power disturbance generator
was tested for proper POW operation and switching stresses. These tests were conducted
using a three-phase 460V, 1780RP M, 150 hp Reliance Electric squirrel cage induction motor
as a load. Phase to phase supply voltages, phase to phase motor voltages, supply current,
IGCT voltage, IGCT current, snubber diode current, and snubber capacitor voltage are all
Summary :
Phase to phase supply voltages, phase to phase motor voltages, supply current, IGCT voltage, IGCT current, snubber diode current, and snubber capacitor voltage are all
