Travel parameters
It is important to monitor the contact times on any given
circuit breaker. However it does not tell you much about the linkage and
mechanism behavior. Today it is a requirement from IEC IEC62271-100 that
reference characteristics for the travel parameters are used during type
testing, routine testing, and service/comissioning work.
Travel parameters that are important for a good breaker analysis:
- Stroke
- Contact penetration
- Overtravel
- Undertravel
- Rebounce
- Speed
- Damping
- Lenght of arcing contact
Mechanical routine testing of circuit breakers
For a factory it imperitive that you have fastening kits
specially developed for the breaker at hand. They need to be very rugged and
last for millions of operations.

Service and comissioning of circuit breakers
If you are a member of a service team that handles comissioning and service
of circuit breakers, you need a flexible kit that handles several breaker types
and still gives you the best possible accuracy.
The equipment
You get a partner that specialize in manufacturing solutions that fits your
requirements. There are several transducer fastening brackets designated for a
given breaker type available, but also flexible kits that will fit most breakers
and mechanisms. |
