Page 5: Section 1 General Information
Basic Unit Description. (1) The basic BE3-25A Auto-Synchronizer monitors both the oncoming generator and bus voltages then permits synchronizing the generator to an energized station bus or to another genera- tor when the following predetermined conditions are satisfied: (a) The frequency of the oncoming generator and the bus are matched to within ±0.1 Hertz. -
Page 6: Frequency/Phase Angle Matching System
(2) Two types of voltage matching are available: (a) "Bipolar" regulator correction signals for use with the summing point input of Basler Electric voltage regulators (types: SSR, SR, KR, and XR) and exciter regulators (types: SSE and SER-CB). -
Page 7: Dead Bus Closing Option
For output contacts, the contacts are closed until the conditions for acceptable breaker closure are attained. NOTE If the voltage regulator is not properly adjusted, the BE3-25A output may not be able to drive the regulator far enough to allow synchroni- zation. -
Page 8: Style Chart
The model number of the Synchronizer is a combination of letters and numbers indicating the features and options. Refer to Figure 1-1 for the style chart which shows the various options and features. Figure 1-1. BE3-25A Style Chart. Courtesy of NationalSwitchgear.com... -
Page 9: Section 2 Theory Of Operation
Basic Unit (With Options) System Theory of Operation. NOTE Even though the BE3-25A always has frequency matching, for pur- poses of discussion, it is considered an option because of the two types that may be selected (summing point or contacts). -
Page 10: Synchronizer Theory Of Operation
frequency (i.e.: the output for a 3 Hertz difference is larger than that for a 1 Hertz difference.) If the Reset jumper is installed to provide internal operation, the signals will continue being output until the phase angle is within the front panel setting. If the Reset function is being controlled externally, the correction signals will continue until the external reset contacts are closed. -
Page 11: Dead Bus Option
(2) The voltage correction signals will drive either a "raise/lower" contact type output for use with motor operated control (MOC) type voltage regulators or a "bipolar" type output for use with the summing point type input of Basler Electric voltage regulators (types SSR, XR, SR, and KR) and for exciter regulators (types SSE and SER-CB). -

Page 28: Operation
If the governor and the voltage regulator are not properly adjusted (refer to the individual governor and voltage regulator manuals), the BE3-25A may not be able to drive the governor or voltage regulator enough to allow synchronization. (All Models.) Set the front panel TEST/OPERATE switch to the TEST position. -
Page 29: Pre-Operational Check-Out
(Options A, B, or W Only.) Refer to Figure 3-2 and connect the Governor Stability Jumper for medium response time at terminals G1 and G2. (Options 1 or 2 Only.) Rotate the front panel % VOLT MATCH switch to select the desired voltage difference (1%, 2%, 3%, 4% or 5%) that is required for synchroniza- tion. -
