Circuit Breaker Analyzer Tests

The circuit breaker analyzer will perform 3 of more specific tests.
They are the a. Timing measurement, b. Motion Measurement, c. Coil Current Measurement.

For a. The CLOSE/OPEN and multiple CLOSE-OPEN option will give you the precise trip/close timing also the reliability of your circuit breaker in effect to corrosion effects.

For b. Where you can connect analog/digital transducers to the analyzer (linear & rotary) you are able to view a curve of the speed of the transition from one circuit breaker operation to the other along with rebound and damping measures. Whereas you are also testing the circuit breakers efficiency in minimizing arcs.

For c. By the coil current measurement and the current vs time curve provided by the analyzer you are inspecting the coil's armature resistance against the control current from hitting the trip point, i.e. the factors behind breaker's response time.

In addition, the DRM dynamic resistance measurement where you measure the contact resistance on-line will give you the life span of your circuit breaker by indicating the effects of the electrical arcs on the contact's resistance (Arcs will increase the resistance). Vibration measurement is when you apply repetitive CLOSE-OPEN commands to test the response reliability of your circuit breaker against corrosion.
