BE1-32R, BE1-32 O/U DIRECTIONAL POWER RELAY APPLICATION The BE1-32R Directional Overpower Relay and the BE1-32 O/U Directional Pages 2 - 4 Over/Underpower Relay are solid-state devices which provide versatility and control in protecting machines against reverse power flow, underpower and overpower conditions.
Sustained motoring can cause PURPOSE severe damage to the prime mover. The Directional The BE1-32R Directional Overpower Relay and the BE1- Power Relay, with its wide sensitivity range, can detect 32 O/U, Directional Over/Underpower Relays sense real levels of reverse real power flow as low as 0.5 Watts...
A definite time delay will generally be provided for the “stop” signal of one minute or more. The Basler Model BE1-32 O/U Power Relay incorporates both over and under power sensing in one relay, which makes it ideal for this application.
With the many options and combinations of options Since the sine of Q equals the cosine of (Q - 90°) the available, the Basler Electric Directional Power Relays relay can be connected to measure only reactive can be adapted to multitude of systems and situations power by adding 90°...
BE1-32R, BE1-32R O/U SPECIFICATIONS (continued) If sensing input range 2, 3, 5, 6, 8 or 9 is selected, the Type B (60 Hz) or Type V (50 Hz) Sensing: Single-Phase input transformers are capable of 10 A continuous (Figure 8) with 30° phase shift. This sensing configuration current, 15 A for 1 minute and 200 A for 1 second.
BE1-32R, BE1-32R O/U SPECIFICATIONS (continued) Type D Sensing: Three-Phase (Figure 10). The type D sensing configuration monitors three line-to-neutral voltages and three phase currents of a three-phase, four- wire circuit and calculates the power flowing in the tripping direction. Relays with this sensing type are calibrated in three-phase watts.
SPECIFICATIONS (continued) Table 2 - Power Range Pickup Settings Each model, BE1-32R or BE1-32 O/U is capable of Inverse time delayed trip is available for the overpower instantaneous trip, definite time delay trip, or an inverse function only. The inverse time delay curve is adjust-...

BE1-32R, BE1-32R O/U SPECIFICATIONS (continued) TARGETS Magnetically latched, manually reset target indicators are optionally available to indicate that a trip output has energized. Either internally operated or current operated target may be specified. Current operated targets require 0.2 A in the output trip circuit to actuate, and trip current must not exceed 30 A for 0.2 seconds, 7 A for 2 minutes,...
