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
