Doble TDR900

DOB-TDR900 Circuit Breaker Test System

Performs timing functions for up to 4 breaks per phase with motion
measurements for any circuit breaker.

The TDR900 is a state-of-the-art Circuit Breaker Test System engineered to
test all types of circuit breakers. The TDR900 provides efficient and accurate
performance measurements for circuit breakers. It allows simple to complex
testing of circuit breakers using a single, rugged, field-portable instrument.

Rugged and Reliable - the TDR900 is a single box solution, providing the
accuracy of a laboratory instrument with durability for field use.
o Complete Test Reports - provided in MS Excel format.
o User-friendly PC interface - the new T-Doble Software with its intuitive
control panel provides quick, efficient and simple testing of circuit
o High Accuracy Motion Recording - a patented digital rotary and linear
transducer provide early diagnosis of mechanical problems.
o Detects main contact and resistor switch timing errors.
o Other analog transducers supported.
o Immune to Interference - accuracy of test results is unaffected by the
severe conditions of electrostatic and electromagnetic interference, normally
present in harsh substation environments.
o Controlled by user supplied PC.
o Data can be plotted, overlaid, analyzed, and printed
o Will import all TR3100 and TDR9000 test result data and test plans T-Doble
Software (included with the TDR900) allows simple configurable display of
results and user configurable reports
