Services Description Service/ Maintenance Circuit Breaker


A circuit breaker is an important equipment to power electric networks. Its importance is due to the protection role it is playing. Hence, it is imperative to assure its proper operation. This is only possible by applying suitable maintenance. The  main  purpose  is  to  help  us  understand, accurately, the real condition of the breaker being tested thus helping targeting the corrective actions. This targeting helps minimize maintenance spending and increase network reliability, hence leading to efficient network management. A power circuit breaker is equipment intended to switch  on  and  off  electric  currents  on  power transmission and distribution networks for routine operations  and  protection  of  other  equipment. Electric transmission system breakups and equipment destruction can occur if a circuit breaker fails to operate because of a lack of preventive maintenance.


Its name, circuit breaker, indicates clearly its role. It breaks electric circuits.  To achieve this purpose, it separates mechanically two points in the circuit to a
certain distance large enough to break the flow of electric currents. Circuit breakers come in a great variety and use different technologies:
Despite the big difference all types share common principals,  they  all  have  to  provide  two  main functionalities highly related:
•   Electrical functionality (Interrupter).
•   Mechanical functionality (Mechanism).


Preventive Maintenance
The need for maintenance of circuit breakers is often not obvious, as circuit breakers may remain idle, either open or closed, for long periods of time. The need to
predict the proper function of circuit breakers grew over the  years  as  transmission  networks  expanded  and carried increasing energy to longer distances.
The technology advance over the years brought low maintenance  breakers  but  it  did  not  bring  more reassurance to network management as to the reliability
of operation. The circuit breaker is, in fact, a black box. The only way to be sure of its condition is to open it for physical inspection. Unfortunately, this way is costly and must be reduced   to   minimum   to   prevent   unnecessarily maintenance.
