The BE1-32R Directional Overpower Relay and the BE1

32 O/U, Directional Over/Underpower Relays sense real

power flow (El cos Θ). These relays are solid-state

devices designed for use in single-phase or three-phase

systems to provide equipment protection for overpower

and/or underpower or to be used for supervisory control

of circuits. Both relay configurations may be used to

monitor either forward or reverse power. In the following

application examples, single-phase connections are

shown for simplicity.
