The TDR9000 Circuit Breaker Test System is a state-of-the-art instrument designed to test all types of circuit breakers. It permits testing up to eight breaks per phase, for a total of 24 main contacts simultaneously. The instrument's high-speed data acquisition circuitry, coupled with interference suppression designed for substation environments, provides accurate test results and records contact bounce time as low as 60 μs. Its modular design allows you to acquire a circuit breaker test system matched to your present needs and upgrade as required. The EHV Contact Timing module measures the opening and closing times of the main contacts and insertion resistor contacts with 100 μs 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.
