Circuit shown in Figure 3-151. Figure 3-151 (a) of the capacitor banks connected into shape, it applies to shaped or Y-connected motor; Fig. 3-151 (b) of the Y-connected capaci
tor banks, it applies to Y-connected motor. Shaped capacitor using connection, the required electrical smaller capacity, but requires higher voltage value (600V or more). Different power motors, C and R selection Table 3-2.
