Circuit breakers must be tested and maintained to reliably clear faults and protect expensive apparatus.
Doble’s TDR circuit breaker test equipment can record even more data when they are combined with Doble transducers, clamps, cable kits and other accessories designed specifically for the variety of circuit breakers manufactured and in service today.
TDR Accessories include digital rotary and linear motion transducers, mechanical adapters, clamp-on current probes and cable sets for monitoring analog signals and contacts from within the breakers control mechanism cabinet.
Simultaneous measurement for the 3 main contacts (open/ closed) and 2 auxiliary contacts, including pre-insertion resistors (if present in the circuit breaker)
Evaluates the synchronism between the circuit breaker poles
Determines the maximum currents, opening and closing times, simultaneously in both coils
Fully analyze circuit breaker’s performance by measuring main contact and resistor contact time, stroke, velocity, over-travel, bounce back and contact wipes
USB PC interface/USB Flash drive interface
Store up to 200 test. records and 100 test plans internally
