Woodward 8440-2189 Microprocessor-Based Synchronizer

FAQ

Q1: What is the Woodward 8440-2189 used for?
A: The 8440-2189 is a Woodward SPM-D2-1040B/NYB synchronizer designed for three-phase generator paralleling applications.

Q2: What type of device is the 8440-2189?
A: It is a microprocessor-based synchronizer in the Woodward SPM-D2-10 series. Its main role is to synchronize a generator with a bus before closing the generator circuit breaker.

Q3: Does the SPM-D2-1040B/NYB support three-phase paralleling?
A: Yes. Woodward lists the SPM-D2-1040B/NYB (8440-2189) specifically in its three-phase paralleling product group.

Q4: What parameters does the 8440-2189 monitor during synchronization?
A: The synchronizer compares generator and bus electrical conditions, including voltage, frequency and phase relationship, and provides control signals to achieve synchronization.

Q5: Can the 8440-2189 control the generator circuit breaker?
A: Yes. The SPM-D2-10 synchronizer is intended to provide the control necessary for generator-to-bus synchronization and breaker closing in paralleling applications. Product information also identifies generator and bus circuit-breaker status indications.

Q6: What documentation is available for the 8440-2189?
A: Woodward identifies Product Specification 37622 and Manual 37617 for the SPM-D2-1040B/NYB configuration.

Q7: Is the 8440-2189 suitable for industrial power-generation applications?
A: Yes. The SPM-D2 series is used in generator paralleling and industrial power-generation applications where controlled synchronization is required.

Q8: What are the dimensions and weight of the Woodward 8440-2189?
A: The commonly referenced weight is approximately 2.0 kg, with approximate dimensions of 216 × 160 × 55 mm. Exact dimensions can depend on the mounting and enclosure configuration, so the original Woodward mechanical drawing should be used for precise cabinet or shipping calculations.
