MCT1605
Multi-Tap Automatic Current Transformer Saturation,
Ratio and Polarity Test Set
Upgradeability
The MCT1605 includes the ability to upgrade the user
interface and testing capability using updates supplied on
a USB memory device and a simple “upgrade” command.
This upgrade capability permits the MCT1605 system to
improve as new testing needs are developed.
FEATURES AND BENEFITS
n Direct Connection to Multi Ratio CT’s - The MCT1605
will directly connect to all taps on multi ratio CT’s to
eliminate lead changes required to test all interwinding
CT ratios, saturation curves and knee points. The
MCT1605 will test all programmed ratios with the push of
one button.
n Large Display - The large graphical display provides the
user with immediate. easy to read test results including
a plot of the CT saturation curve. This display also
provides the user with simple, easy to read test results for
Ratio and Polarity Test.
n CT Saturation, Ratio and Polarity Automated Testing
- The microprocessor-controlled output fully automates
testing of CT’s. This automated testing simplifies CT testing
and reduces testing time. Automated testing is accomplished
directly on the MCT1605 or via PowerDB Lite.
n CT Demagnetization - During operation and routine
DC winding resistance testing, it is possible for a CT
to become magnetized. The MCT1605 includes an
automated CT Demagnetization function, which allows
determination of accurate Knee Point as well as stable,
repeatable test results, and reduces test time.
n Insulation Test - The MCT1605 includes a 500/1000V
insulation test system to verify the CT secondary winding
and secondary wiring. This insures that the secondary
insulation has not degraded and will continue to perform
its function during high current faults.
n CT Burden Measurement - The CT Burden test ensures
that the CT secondary load is properly connected. A CT
load that is not properly connected can become a fire
hazard.
n CT Winding Resistance Testing - The CT Winding
Resistance test aids in identifiying shorted or open
windings and can also aid in identifying any loose
connections.
n Complete CT Testing - The MCT1605 system
provides a complete CT saturation, ratio and polarity
test. Eliminating the need for multiple pieces of test
equipment to perform a CT test. All test are performed in
compliance with IEEE C57.13.1 test guidelines.
n Full QWERTY Keyboard - The field ruggedized full
QWERTY keyboard simplifies nameplate data input.
n Test Result Report - The MCT1605 offers storage of
complete test files in an easy-to-use, versatile format
that permits upload to PowerDB Lite, or printing test
results using the optional external printer. These options
provide a simple, complete, easy way to store over 200
test results and saturation curves. All test results can be
catalogued and stored in the MCT1605.
n High Voltage Warning
Indication - The MCT1605
can produce a high voltage
output. To ensure the
safety of the user, a high
voltage warning is issued
via both the MCT1605 and
the PowerDB Lite interface
prior to the presence of any
output test voltage.
n Manual Operation - The
MCT1605 is also supplied with a manual voltage output
control knob. This permits the user to perform any test
required manually
if only a spot check is required. This allows the user to
ensure that test results are correct, assisting in diagnosis
of a faulty CT.
n Configurable Test Plans - Configurable Test Plans can
be associated with a specific CT and saved along with
results simplifying ongoing monitoring and profiling
of CTs.
