WD47 Typical Hookup
WD47 Operation
WD47 phase sequence relays are designed to monitor the correct phase
rotation and loss of phase of three phase ac systems from 50 to 400 Hz. An
incorrect phase sequence or loss of any phase will cause the WD47 to pickup.
When the phase sequence is corrected or the lost phase is restored the
contacts dropout. Red LED's light to indicate a fault condition. A green LED
indicates power to the relay. The WD47 is often used to detect reverse phase
rotation or loss of phase to generators, busses, motors, and transformers.

WD47 Connections
Apply a nominal, three-phase input with the correct phase sequence.
The output relay should dropout and the green LED should light.
Apply a nominal, three-phase input with an incorrect phase sequence.
The output relay should pickup and the red LED should light.
Apply only one or two phases with the correct phase sequence. The
output relay should pickup and the red LED should light.
