Case Studies

Major Transportation Hub Goes Dark

Project Name:

Major Transportation Hub Goes Dark

Description:

Potomac was able to replace a transformer within 48 hours to get this station fully back online. While the lead time would normally be at least several months for a replacement transformer, Potomac has the resources to quickly locate and procure used equipment, performing any necessary modifications to ensure the electrical distribution equipment will operate to the required specifications.

Regular Maintenance Prevents Major Outage

Project Name:

Regular Maintenance Prevents Major Outage

Description:

While performing scheduled maintenance at a military installation, Potomac technicians discovered insulation that was compromised, apparently due to the improper assembly of equipment. As a result, safety equipment was not properly in place and the 13,000 volt switchgear was in imminent danger of failure. This failure could have led to an explosion that would have damaged additional equipment and possibly weeks of downtime. Potomac was able to perform repairs within 24 hours with very little downtime.

Federal Facility Back Online within a Week

Project Name:

Federal Facility Back Online within a Week

Description:

The remnants of a hurricane dumped over 5 inches of rain on the nation’s capital. An underground river flooded several critical agencies downtown. Potomac received an emergency call when it was clear GSA was overwhelmed and needed additional support fast. The flooding was so severe, that one facility’s 65×20’basement was now 10 feet deep – fully submerging their switchgear.  Potomac Testing crews worked around the clock to pump the water out, assess damage and completely rebuild every element of the 13,000 volt switchgear including 18 circuit breakers, instrumentation, metering, and protection. Temperature and humidity control were critical in this government facility. Potomac was able to get the first section back online within a week so that air handlers, chillers, dehumidifiers were fully back in operation. Potomac was quickly asked to handle an adjacent flooded government facility as a result of this fast, successful work.
