Circuit Breakers

With aging electrical infrastructure, utilities and industrials have to support equipment at the end of useful life and to deal with consequences of failed equipment. Many utilities noted their concerns about difficulties in recovering substations after faults, accidents and natural disasters.

Having a portable, mobile substation allows for quicker system recovery (Rapid Recovery), while maintaining safety. Utilities are simply storing the portable substation in a central, convenient location for easy transport to the needed area. Very rarely does a fault affect both the transformer and distribution switchgear, so Arizona Electrical Apparatus also offers a portable design with just replacement switchgear, which is smaller, lighter and easy to maneuver. Complete portable substations are avaliable as well.

Portable substations can also be incorporated into existing substations where newer transformers and other equipment still have useful life, even as the original switchgear is no longer dependable. The portable sustation can take the place of the aged switchgear and support the rest of the substation for a period of time. When a complete new substation is procured, the portable equipment can be moved to another location.
