BE1-32R, -32 O/U FUNCTIONAL DESCRIPTION

Figure 3-3. Type E Sensing With ACB Rotation
Type B Or V Sensing
Type B (60 hertz) and Type V (50 hertz) sensing relays monitor a single phase-to-phase voltage and one phase
current to determine directional power flow. An internal 30
phase delay network (frequency dependent) aligns
the voltage signal with the current signal. Figure 3-4. shows the phasor representation monitoring phase A
current and phase A to B voltage with ABC rotation. Figure 3-5. shows the phasor representation monitoring
phase A to C voltage with ACB rotation.
