Circuit Breaker and Switchgear Servicing & Maintenance
The need for Maintenance of Circuit Breakers is often NOT obvious as circuit breakers may be in working condition and not showing any signs of complications. Breakers should be routinely opened and closed several times in succession to verify proper operation and remove any accumulation of dust or foreign material on moving parts and contacts.
Circuit breakers deserve special consideration because of their importance for routine switching and protection of downstream equipment. Electric transmission system disruption and equipment destruction can occur if a circuit breaker fails to operate due to a lack of preventive maintenance.
This Maintenance includes:
Visual and Mechanical Inspection
Electrical Tests
Test Value Evaluation
Lubrication, cleaning, resurfacing, plating and other methods of restoration
