Why Utility Companies use our Temporary Power Restoration Devices.

  • Power-Back Temporary Service Restoration Autotransformers. It saves time and money,
  • Now you can restore lost power in minutes and schedule permanent repairs at a later date instead of having to make repairs immediately
  • They are designed for both overhead 120/240 and underground 120/240 3 wire systems.
  • Restores Power to Both Homes and Businesses.

Early models of transportable autotransformers were heavy, weighing in between 250 and 400 lbs. Unloading and loading back on the truck required a hoist, and they often took two persons to move in place at the meter pan.

Bridgeport Magnetics specializes in toroidal transformers that are much lighter and smaller than traditional E-I models. For example, when we introduced our Power-Back series in 2008, it came out 40-50% lighter than the competition.

2006 to 2021 Power-Back models featuring sturdy stainless enclosures and wide 10” wheels now reside countrywide on power utility depots and trucks. GPS tracking systems are available to follow deployment and ensure recovery after line repairs. In addition, two larger wheeled models rated 30KVA and 50KVA are designed for multi-service use in condominium communities.

At Bridgeport Magnetics, development never ceases. In the fall of 2021 we are introducing two additional Power Back models, both featuring non-metallic enclosures that do not require connection to the customer’s ground or a driven ground rod.

  • The 20KVA PB-LIGHT features an aluminum wheeled base. At only 110 lbs. and a low center of gravity, it is even easier to handle in rugged terrain and in the deep of winter.
  • The 10/20 KVA TRIDENT. A carry-in model. Features three individual components: Two 10KVA transformers and a control unit that attaches directly to the meter pan. At 45 lbs. the plug-in transformers comply with union regulations allowing 60lb. max carry weight. Trident is compact and can reside on a light truck or even in a car trunk for immediate use. In addition, the all-resin enclosures do not require grounding

TRIDENT Flex Carry In (does not require grounding) can restore a lost Phase or Neutral in households with up to 200 Amp service by means of one or two identical 10KVA autotransformers, each weighing 46 lbs. and a control unit integrated with a plug-in meter adapter (8lbs). 

Each autotransformer is controlled by an individual circuit breaker enabling two output power selections.

The transformers feature a carrying handle and means for holding the cable and plug in place when not in use. They fit easily on a light truck or in a car trunk and are carried in to be placed on the ground below the residence meter pan.

The toroidal autotransformers are encapsulated in a cup shaped enclosure molded from high-strength flame rated ABS polymer. The same resin is used in the control unit enclosure rendering all surfaces non-conducting.

The non-metallic enclosures do not require grounding to a driven spear or residence ground for personal safety.
