Atec TDR900 User Manual
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.
TDR900 Benefits:
• Rugged and Reliable - the TDR900 is a single box solution, providing the accuracy
of a laboratory instrument with durability for eld use.
• Complete Test Reports - provided in MS Excel™ format.
• User-friendly PC interface - the new T-Doble Software with its intuitive control panel
provides quick, efcient and simple testing of circuit breakers.
• High Accuracy Motion Recording - a patented digital rotary and linear transducer provide early diagnosis of mechanical problems.
• Detects main contact and resistor switch timing errors.
• Other analog transducers supported.
• Immune to Interference - accuracy of test results is unaffected by the severe conditions of electrostatic and electromagnetic interference, normally present in harsh
substation environments.
• Controlled by user supplied PC.
T-Doble Software (included
with the TDR900) allows simple
congurable display of results
and user congurable reports
TDR900 Features:
TDR900 controls circuit breaker trip and
close commands, allowing the user to
perform the following operations:
• Trip (O)
• Close (C)
• Reclose (O-0.3s-C)
• Tripfree (CO)
• O-CO
• O-0.3s-CO
• First Trip (O)
• Slow Close (C)
• Self Diagnostics
The TDR900 comes with New T-Doble
Software for improved data management
capability.
• Intuitive and clear: easy-to-use test
plans and test results
• Data can be plotted, overlaid, analyzed,
and printed
• Will import all TR3100 and TDR9000
test result data and test plans
