Phone 618-654-2341 fax 618-654-2351 be1-25a automatic synchronizer the be1-25a automatic synchronizer is a microprocessor based system including features to bring any generator on line in a minimum time, from small diesel units to lar...

  • Page 2: Introduction

    Be1-25a introduction 2 the be1-25a automatic synchronizer initiates closure of the generator circuit breaker when voltage magnitude, slip frequency, and phase difference are within preset limits. This capability minimizes system transients that can result from differences in speed, voltage level, or...

  • Page 3: Application

    Be1-25a application 3 the basic be1-25a synchronizer, without any options, may be used to close the breaker between a generator and bus when the generator frequency and phase angle are within prescribed limits. A voltage acceptance option (a1 or a2) may be added to permit breaker closing only if the...

  • Page 4: Functional Description

    Be1-25a functional description the be1-25a is contained in a standard, 19-inch, rack- mount case with all controls and indicators visible through the front cover and accessible by removing the front cover. The active circuits are contained within plug-in modules. The primary control module (called t...

    Be1-25a 6 generator select 2 through 6 - these five inputs select any one of the five memory registers that are reserved for the breaker closing times. When any one (of the five) contacts are closed, a particular register (i.E., breaker time) is selected. When none of these contacts are closed, the ...

    Be1-25a 7 option modules, continued option v3 provides a pulsed contact closure like the v2 option except that when the voltage difference is within 20 volts, the correction pulse width is reduced linearly with voltage difference. This reduction in correction pulse duration reduces “hunting” and ove...
