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.

The TDR9000 provides testing of up to eight breaks per phase, for a total of 24 main contacts simultaneously. The EHV The 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 high speed data acquisition circuitry, coupled with interference suppression specifically designed for electromagnetic interference substation environments, provide accurate test results and records contact bounce time as low as 60 μs.

The TDR9000 Circuit Breaker Test System provides efficient, accurate measurements of circuit breaker dynamic timing and motion.
