Introduction
The TDR9000 Circuit Breaker Test System provides efficient, accurate measurements of circuit breaker dynamic timing and motion.
Field proven for over 25 years, more than 2,300 Doble circuit breaker diagnos-
tic instruments have been sold.
Benefits
• Accurate measurement of grading capacitors capacitance values, and
insertion resistor resistance values –
for grading capacitors and insertion resistors testing eliminates the need
for separate measuring instruments. No other product on the market can
match the TDR9000 in this capability.
Immune to Interference – accuracy of test results is unaffected
•
by severe conditions of electrostatic and electromagnetic interference, present in harsh substation environments.
• Modular Design – customize the system to match present
testing requirements; field upgrade the system as required,
to protect the capital investment.
• High Accuracy Motion Recording – a patented digital rotary
and linear transducer provides early diagnosis of mechanical
problems, auxiliary switch and main contact timing errors.
built-in, precision measurements
• Rugged and Reliable – the TDR9000 is a single box solution,
providing the accuracy of a laboratory instrument with
durability for field use.
• Self-Diagnostics – self-diagnostics on demand ensures accurate
and valid test results.
• User-friendly PC interface – an intuitive control panel on
your PC provides quick, efficient and simple testing of circuit
breakers.
• Comprehensive Testing – accurately measures all essential
parameters of a circuit breaker in a single test for accurate
diagnostics of the circuit breaker operation.
Description
The TDR9000 is a state-of-the art Circuit Breaker Test System
engineered to test all types of circuit breakers. The modular construction of the TDR9000 allows testing of simple circuit breakers,
to very complex circuit breakers, using a single, field-portable and
rugged instrument. The modular design allows users to acquire a
Circuit Breaker Test System matched to today’s specific testing
applications and permits easy upgrades in the field to expand the
capabilities to test different or more complex apparatus. The modular design results in complete usage of its capital investment and
simultaneously provides an upgrade path to test future circuit
breaker designs.
Packaged in a compact, portable and sturdy case, the TDR9000 is
the singlebox solution for Circuit Breaker Testing in the field.
The TDR9000 provides testing of up to eight breaks per phase,
for a total of 24 main contacts simultaneously. The EHV The
EHV Contact Timing Module measures the opening and closing times
of both the main contacts and the inser
µs second resolution. During a separate test, it measures the capaci-
tance of grading capacitors. This substantially r
number of channels required for circuit breaker testing. The highspeed data acquisition circuitry, coupled with interference suppression
specifically designed for electro magnetic interference substation
environments, provide accurate test results and records contact
bounce time as low as 60
During a Trip/Close test, the TDR9000’s Motion Module simultaneously records the output from up to six digital rotary/linear transducers.
The digital rotary/linear transducer provides high accuracy measurements of ± 0.1%. This patented field-proven device provides precise
details of the operating mechanism’s performance for damping, total
travel, over travel, rebound, average velocities and instantaneous
velocity. It also supplies details about contact wipe and contact
bounce. Digital transducers overcome errors associated with analog transducers,
such as slide wire transducers, where wire slippage or distortion can contribute
significant errors to the measurements.
The TDR9000 System Panel with Trip and Close Command and Trip and Close
Command Current Recording as well as general purpose event recording modules
for measuring urrents/voltage and breaker/relay auxiliary contacts. A graphic
recording of the trip and close coil current provides useful insight into the electrical
and mechanical condition of the trip and close mechanisms.

TRX™ Software
The Windows based TRX software controls the TDR9000 and stores test results and
test plans. TRX Software uses an industry standard SQL compliant client server
database architecture.
For ease of analysis, TRX displays test data and test results in tabular or graphical
form. Time-related information such as travel, velocity, contact transition, trip
and/or close coil currents, analog and auxiliary contact channels are displayed
graphically. TRX Software organizes Circuit Breaker Test Plans and test types by
user-defined regions, locations, substations, manufacturers, models and serial
numbers along with the historical r
productivity of test personnel is improved.
TRXField, an independent component of TRX Software, quickly allows Test Plan
creation, switching device Testing and Test Result analysis. The operator can specify
expected results. The software compares the actual test results with the user
defined expected test results to make a pass or fail determination.

TDR9000 Control Panel
Efficient operational Circuit Breaker
verification is accomplished with the
TDR9000 Control Panel. This userfriendly PC interface allows an
operator to configur
for testing via a simple point and click
mouse operation. The TDR9000
Control Panel’s intuitive controls allow
circuit breaker testing without the need
for an elaborate test plan. Test results
such as contact timing and instantaneous velocity and displacement, can
be displayed graphically for instant
analysis, while an optional 8.5 inch
thermal printer, provided with the
TDR9000, prints out the test results
for a paper record. A test created in the
TDR9000 Control Panel can be saved
for future use on the PC.
