  • Page 6: Section 1 • General Information

    SECTION 1 • GENERAL INFORMATION PURPOSE BE1-32R, Directional Overpower and BE1-32 O/U, Directional Over/Underpower Relays sense real power (IE times cos ). These relays are solid state devices that are designed for use in single-phase or three-phase systems to provide equipment protection for overpower and/or underpower, or for use in the supervisory control of circuits.

  • Page 7: Example 2, Co-Generator Control

    The BE1-32R, Reverse Power Relay must be sensitive enough to detect power levels lower than those required to motor the generator. Sensitivity is much more important on steam and hydro turbines than on reciprocating engines and gas turbines. Table 1-1 represents the reverse power requirements to motor a generator when the prime mover is rotating at synchronous speed with no input power supplied by the prime mover.

  • Page 8: Example 3, Generator Overload

    T1 nor T2 alone can supply the total load. The BE1-32 O/U, over/underpower directional relays can protect this distribution system by providing overload protection for each transformer (overpower function) or by sensing power flow through the transformers (reverse power function) in an undesired direction.

  • Page 9: Example 5, Delayed Electrical Trip

    Figure 1-5. The reverse power relay delays breaker tripping until trapped steam has been removed from the piping. In this case, as separate direct-tripping anti-motoring relay can be used to protect for situations not related to an automatic shutdown of the unit. Figure 1-5. Single-Phase, Non-Electrical Trip Supervision BE1-32R, -32 O/U GENERAL INFORMATION...

  • Page 10: Example 6, Breaker Opening Detection

    When breaker N opens, real power reverses from normal and flows toward the utility. This power may be flowing to the tapped load. At this time, the relay operates and causes the 52 breaker to open. BE1-32R, -32 O/U GENERAL INFORMATION...

  • Page 11: Example 7, Reactive Power (Vars) Detection

    Excessive heating results in the damper (amortissuer) windings, slot wedges, and in the surface iron of the rotor due to the slip frequency current flow when a synchronous generator is operated as an induction generator. BE1-32R, -32 O/U GENERAL INFORMATION...
  • Page 12 Figure 1-10 illustrates how a single-phase BE1-32R or BE1-32 O/U can be connected to measure either real power (watts) or reactive power (vars) flow in a three-phase system. Notice the difference of phase relationship between the alternate connections in Figure 1-10.
