To conduct a motion analysis of a circuit breaker, a certain type of transducer is needed. Together with DV Power testing instruments, transducers help a user to check the breaker’s mechanism and its behavior during the operations of opening and closing. In this way, the performance of the circuit breaker can be precisely evaluated.
The measurements can be done by using a linear or rotary transducer. The linear transducer reads the length in inches or centimeters, while rotary transducer reads the movement in degrees and a user needs to convert it to length. DV Power supplies DV Win software with its instruments which automatically converts the readout of a rotary transducer.
If one mechanism is operating all three phases, then only one transducer is needed. In another case, when one mechanism for each phase exists then one transducer should be used for every mechanism.
