BE1-32R, -32 O/U FUNCTIONAL DESCRIPTION
3-7
Type E, Three-Phase Sensing
Refer to Figure 3-10. Type E sensing configurations monitor three line-to-line voltages and two of the phase
currents of a three-phase, three-wire circuit and calculate the power flowing in the tripping direction. The relay
measures actual power under balanced or unbalanced conditions. The power equation assumes that conditions
are balanced. Type E sensing configurations are phase rotation sensitive. The range switch for this type
sensing is calibrated in three-phase watts.
