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

3-5

Type C, Three-Phase Sensing

Refer to Figure 3-8. Type C sensing configurations monitor three line-to-line voltages and a single-phase current
of a three-phase, three-wire circuit and calculate the power flowing in the tripping direction. The relay measures
actual power even if the system voltages are not balanced. Therefore, the power equation using E

AVE

is

approximate. Type C sensing configurations are not phase rotation sensitive. The range switch of this type
sensing is also calibrated in three-phase watts.
