MAINTENANCE :
When switchgear malfunctions, the consequences are often catastrophic. Damage to the switchgear itself can be extremely expensive, but that pales in comparison to corollary damage and the potential hazards to people. Thus, implementing an effective switchgear testing, inspection, and maintenance program is essential. Even switchgear labeled “maintenance free” requires periodic testing and maintenance.
RETROFIT :
Retrofitting refers to the process of updating older equipment with new technology. In the world of industrial electrical equipment, retrofits are regularly used to add functionality to many types of electrical equipment, including circuit breakers, contactors and switchgear.
Why Retrofitting?
Retrofitting of switchgear is a cost effective approach in extending life span of the existing switchgear while incorporating the latest technology into the system. In most instances retrofitting of the breakers can be carried out with little modifications to the existing breaker compartments. The replacement circuit breaker can enhance the life of the switchgear as the original circuit breakers are technically obsolete, too costly to maintain on account of no availability of original spares, unable to interrupt or withstand the ever increasing fault current, or beyond repair due to mechanical wear and tear.
Benefits of Retrofit:
- Increased operating reliability and safety
- Enhanced short circuit ratings available
- Reduced maintenance and environmental impact
- Elimination of hazardous materials such as asbestos
- Service life can be extended
