6 FT Flexitest family | Descriptive bulletin
Flexitest test switches provide a safe, reliable, and cost-effective
means to wire the output of relays, meters, and other associ-
ated equipment to external devices for in-service testing.
3.1.Safe and convenient
All measurements and tests can be performed at the front of
the switchboard, without taking any devices out of service, and
without the need to access wiring at the rear of the devices.
Flexitest switches and test plugs have all the features necessary
for applications involving the safe measurement and isolation of
individual currents, voltages, and digital I/O signals to facilitate
testing of substation instrumentation and protection devices.
The make-before-break current shorting feature allows test
personnel to quickly and safely isolate equipment from current
transformer (CT) circuits.
Voltage measurements can also be made directly on Flexitest
switches, without disturbing existing connections. There is a
test clip located on the top of each pole that allows connection
with standard spring clip test leads.
3.2. Fast and reliable
When test plugs are used, any number of circuits may be tested
in rapid succession. One plug properly connected can test all
instruments or meters of a particular type.
3.3. Maximum flexibility
Test switches can be assembled in a variety of different arrange-
ments, to match customer requirements. To build new or view
existing Flexitest Switches and FT-19R panels, please visit our
interactive FT-1 Configurator website at http://ft1switch.com
(see page 15).
3.4. Security
With the cover in place, a meter seal can be placed through
either of the cover studs of any Flexitest switch to prevent unau-
thorized access to the switch. As an additional feature, a clear
cover is available that can also be installed with the switch-
blades in the fully open or closed positions. In addition, a barrier
has been incorporated into the cover to prevent knife switches
from being left partially open. Optional padlocking provisions are
available for most covers allowing access to authorized person-
nel only.
3.5. Quality
With over 50 years of field proven applications, ABB is the
test switch manufacturer with the highest quality and largest
installed base in North America. ABB’s Flexitest test switches
have been an industry standard for years.
