Applications
Single-Phase Measurement and Ganged Switching
Figure 3.1 shows a single-measurement and ganged switching application. The
SEL-734W uses one measured voltage, such as from a CPT, and one SEL-WCS
to make switching decisions and provide power system monitoring.
Three-Phase Measurements and Ganged Switching
Figure 3.2 shows a three single-measurement and ganged switching application. The
SEL-734W uses one measured voltage, such as from a CPT, and three SEL-WCS
devices to make three-phase switching decisions and provide power system monitoring.
