TDR9000 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 diagnostic instruments have been sold. Benefits • Accurate measurement of grading capacitors capacitance values, and insertion resistor resistance values – built-in, precision measurements 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...

TDR9000 EHV Contact Timing Module measures the opening and closing times of both the main contacts and the insertion resistor contacts with 100 µs second resolution. During a separate test, it measures the capacitance of grading capacitors. This substantially reduces the required 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 µs. During a Trip/Close test,...

Efficient operational Circuit Breaker verification is accomplished with the TDR9000 Control Panel. This userfriendly PC interface allows an operator to configure the TDR9000 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....
