As part of a modernization project to establish their desired electrical control functionalities, Fannie Mae has been elected to modify existing electrical equipment.
In lieu of replacing the existing electrical equipment to achieve the desired intent, the engineers and electricians undertook field retrofit services of the existing switchgear lineup at their facility in Herndon, VA. This approach resulted in cost savings and time savings and reduced customer outages.
Specific AC/DC control modifications
Existing switchgear lineups are often in good condition but lack many functionalities to suit a client's need
Existing switchgear lineups are often in good condition but lack many functionalities to suit a customer’s unique requirements.
Instead of replacing the equipment to achieve unique requirements, various benefits can be realized by retrofitting. This includes significant cost savings, reduced project duration, and minimal interruption of existing building operations.
To meet the customer’s desired requirements, the team investigated the internal circuitry of the switchgear lineup and ascertained the specific AC/DC control modifications of the existing switchgear lineup to accomplish the desired operating criteria.
Work performed under this project included:
- Evaluating Sub-Components of Breakers and Relays
- Engineered Shop Drawing Modifications
- Installation of New Wiring Harnesses
- Control Wire Terminations
- Replacement of Spring Charging Motor Mechanisms
- Main-Tie-Main Interlocking
The complete replacement of switchgear is often unnecessary and too costly. It won’t cost they anything to hear the specific recommendations on how they can save money.
