 Beckwith
Systems Engineering (BSE) continues to enhance our services and solutions
to our customers by expanding our engineered systems. With qualified staff,
contract engineers, and certified suppliers, we provide a full range of
system solutions to meet the demanding requirements of today’s power providers
and users.
BSE offers comprehensive systems for utility, industrial
and commercial power networks that include:
- Protection systems for generators, transformers, and interties
- Motor bus transfer systems
- Synchronizing systems
- Transformer control and paralleling systems
- Volt/VAr management systems
 We
can manage a project from concept to commissioning to performance testing,
and can also supply the components and products for total system solution.
BSE combines a broad range of consulting engineering knowledge, multidisciplinary
expertise, and the right products for the project to offer quality solutions
that are successfully executed.
 BSE
can provide you with complete solutions that include design, cost estimating,
specification development for procurement, detailed engineering, component
procurement, bid evaluation, and products that implement the solution.
We have the ability to integrate the initial technical and financial feasibility
with design and cost estimates in order to allow evaluation of the project
prior to starting the detailed design engineering.
Beckwith Electric recognizes industry changes and trends
and has put together diversified product and system vendors, as well as
engineering resources, to assist our utility and industrial customers
with these challenges. With almost forty years of utility and industrial
experience, BSE provides the systems necessary to take projects to successful
execution and completion, and complete them on time and within budget.
For your next project, contact a Beckwith Electric Representative for
your free consultation.
Protection Systems
Protection Systems feature the use of IPS (Integrated Protection Systems®)—
microprocessor-based relays which use digital signal processing technology
to provide protective relaying functions for generator, transformer, or
intertie protection. Each relay provides “pick and choose” protective
functions, which allow users to select functions to customize relays for
their specific application needs. Each Integrated Protection System also
includes the IPScom® Communications Software for monitoring and recording
capabilities, and offers options such as IPSplot® Oscillograph Analysis
Software to display and print oscillographic data, a Human-Machine Interface
module to provide local operation and metering, a Target module with target
and output LEDs, and a redundant power supply. Protection Systems can
be housed in enclosure cabinets. Learn More
 Motor
Bus Transfer Systems
The utility-grade Syncrotran System consists of a Transfer Logic Controller
and a Power Transfer Relay. The system performs all of the necessary logic
and control functions for the motor bus transfers in two directions by
automatically selecting from either fast, in-phase or residual voltage
methods. The relays allow the Transfer Logic controller to supervise a
fast transfer by monitoring the phase angle between the motor bus and
the new source, blocking transfer if the angle is excessive. If fast transfer
is impossible because of excessive angle, the Power Transfer Relay offers
the option of closing the motor bus in-phase with the new source at the
next pass through zero degrees. Should system conditions prevent transfer
by either method, the Transfer Logic Controller contains a circuit that
measures bus voltage, regardless of the frequency, and allows a residual
transfer to occur when the motor bus voltage has decayed to a safe level.

Synchronizing Systems
Synchronizing Systems are designed to provide both a manual and an automatic
synchronizing function for one generator or multiple generator breakers.
Control switches in the front panel provide for manual raising and lowering
of both speed and voltage of the generator in order to match the frequency
and voltage prior to synchronizing. Digital frequency meters and volt-meters
provide both generator and bus measurements. An operator is assisted during
manual synchronizing by both a synchroscope and synchronizing lights.
Synchronizing Systems typically include: a Generator Control Unit that
automatically matches generator frequency and voltage levels to those
of the bus; a Syncrocloser Unit that sends the closing command to the
breaker to provide breaker closure at the precise moment of phase coincident;
and a Syncrocloser Check relay that provides a permissive function, verifying
that voltage and phase angle conditions are within preset limits before
allowing the breaker to close. Learn More
Transformer Control And Paralleling Systems
Extending the life of some of your most valuable assets can be problematic
when the original equipment supplier no longer exists or supports the
control device. Many times, it makes sense to upgrade your outdated substation
transformer or regulator control system. Beckwith Electric’s LTC Control
Systems are designed by Beckwith Systems Engineering (BSE) to be used
with load tap changing transformers or regulators having various types
of load tapchanger mechanisms (old to new). Enclosure designs range from
customer-specified to standard NEMA enclosures. Each system utilizing
the M-2001B Tapchanger Control includes an Adapter Panel that matches
the unit being retrofitted. Enclosures can also integrate the associated
control switches for local control, auxiliary relays, test jacks, convenience
outlets, paralleling schemes and even dial-up analog cellular to facilitate
site-specific remote control. Your choice of paralleling schemes include:
circulating current method, DVAR1 method, DVAR2 method, Daisy-Chain, and
Daisy Chain Wireless. (Both types of Daisy Chain paralleling are only
available with Autodaptive® LTC controls.) Our engineers will help you
decide which is best for your application. Learn More
 Volt/VAr
Management Systems
Beckwith Electric has “raised the bar” in the field of controls and is
providing innovative, automatically adapting (Autodaptive®) controls that
change their operating parameters to adjust to ever-changing distribution
system conditions. Having the ability to adjust operating parameters and
change settings of controls based on dynamic distribution system changes
is what Autodaptive® technology is all about. “The system is the solution,”
wherein the whole is greater than the sum of its parts. The synergistic
result of using all Autodaptive controls in the distribution system provides
performance beyond that which has been experienced using conventional
controls.
Managing volt/VArs in the distribution system is best using
automatically-switched capacitor controls, and LTC transformer and regulator
controls. Distribution system losses can be significantly reduced by effectively
managing VArs through the coordinated control of these devices. Reducing
losses, tap change operations and maintenance all significantly improve
system efficiency and performance, as well as reducing operating costs—all
of which increase utility revenue and can defer capital expenditure.
The focal point for Volt/VAr management/control tends to
be at the distribution level, and generally contains automation of some
sort. At the distribution level, there are several major system components
that can affect the management of volts and VArs. These components are:
load tap changing (LTC) transformers, load tap changing (LTC) line regulators
and capacitor bank controls (pole top and substation step bank), all of
which can lend themselves to automation. In any good evaluation of a Volt/VAr
Management System, all of these components must be considered individually,
as well as collectively, to ascertain the most efficient, viable method
of control.
