y Recloser Trip and Close Power is charged from C1, C2, C3 in UPS module.
y C1 is used for Trip power, C2, C3 are used for Close power.
y Trip(Close) runs when IGBT is “ON”. MC runs and the charged Capacitor transfer the Power
to TC(CC), eventually Recloser runs.
y F1, F2 are Fuses to protect IGBT from MC damage. These are on Analog Board.
