G&W offers a full-range of automation
products and services that can be customized to fit your requirements,
your budget, and your schedule.
SCADA-Ready Switches
These switches are ordered with the very minimum requirements
for future automation. Since our manual switches were designed
with future automation in mind, most additional automation
components can be easily and economically added when you are
ready.
Motor Operated Switches
These are switches ordered with motor operators and controllers
for local electronic operation. All controls are ready for
connection to an RTU for complete remote automation.
Fully Automated Switches
These are motor operated switches and controls with an RTU,
communication device, and any required voltage and current
sensing. G&W will integrate and test these components
as a package for your unique application.
Automation Consulting
Not sure how to improve your system reliability? Not certain
which switch configuration is right for your application?
Not to worry. G&W will help you select the products that
best fit your needs.
Master Stations
Complete master stations are available to provide system flexibility.
From a single control system to a fully integrated solution,
to dual redundant, multiple networked work stations and a
full graphics operator interface.
Automation Accessories
G&W can supply a number of accessories to further enhance
the functionality of your automated switch. Most are available
for upgrades on existing manual switches so you can add-on
to and upgrade your system at your pace.
Voltage Monitoring
– G&W can supply voltage sensors that indicate the
presence or loss of voltage for a feeder. Alternately, we
can provide potential transformers (PTs) for analog voltage
measurements. These analog measurements, when coupled with
analog current measurements, can provide real-time load and
metering values. The PTs may be connected external to the
switch, or connected inside an SF6 switch tank.
Current Monitoring
G&W can supply internal or external current transformers
(CTs) for both overcurrent protection monitoring as well as
metering analog values.
SF6 Pressure Monitoring
For SF6 switches, we can provide either a low pressure warning
device or, if cold temperatures are normal in your area, a
density switch to indicate the unlikely event of a low dielectric
condition.
Faulted Circuit Indicators
Monitoring unprotected load taps for downstream faults is
a necessity for automated switches. Faulted circuit indicators
can be ordered to provide indication of a downstream fault,
thereby preventing operation into a fault.
Customer-Specified
Accessories
G&W can integrate other monitoring, control, or date acquisition
devices with our switches and automation products. Bring us
your requirements, we’ll deliver your solution.
