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: • ugged and Reliable - the TDR900 is a single box solution, providing the accuracy R of a laboratory instrument with durability for field use. • Complete Test Reports - provided in MS Excel™ format. • ser-friendly PC interface - the new T-Doble Software with its intuitive control panel U provides quick, efficient and simple testing of circuit breakers. • High Accuracy Motion Recording - a patented digital rotary and linear transducer pro vide early diagnosis of mechanical problems. • Detects main contact and resistor switch timing errors. • Other analog transducers supported. • mmune to Interference - accuracy of test results is unaffected by the severe condiI tions of electrostatic and electromagnetic interference, normally present in harsh substation environments. • Controlled by user supplied PC. 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 T-Doble Software (included with the TDR900) allows simple configurable display of results and user configurable reports • 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. • ntuitive and clear: easy-to-use test I plans and test results • ata can be plotted, overlaid, analyzed, D and printed • ill import all TR3100 and TDR9000 W test result data and test plans
