Many critical processes and infrastructures rely on electric power for their operation. Certain infrastructure such as public health systems, the communications industry and crucial government services have key roles to play. A single power outage can affect thousands of end users. A portable transformer is a temporary replacement for a power line failure. It's rapidly deployed, usually within 12 to 24 hours, to sites where power is required. Its fast deployment capacity is one of the main advantages. Portable transformers are used to provide power in plant modification projects that require greater electrical loads, construction projects, government facilities and industries.
Mobile transformers play a vital role in maintaining the security and reliability of a grid system. The availability of mobile substations and mobile transformers allows operators to quickly restore electrical service during natural disasters, forced outage repairs, equipment failure and acts of terrorism. Portable transformers function as part of the main, or permanent, grid system when they supply power in such situations. They are an integral part of a utility's electrical system.
Portable transformers serve as substitutes for conventional substations in areas cut off from the main grid network. They are frequently deployed in places where the supply of electricity does not meet its demand. A stand-alone portable transformer reduces commission labor expense and engineering installation. It also reduces integrated and wiring testing costs, field assembly, quality issues and on-site labor costs. Portable transformers are designed to be tamper-proof and safe, which minimizes security concerns. They require less space than conventional, large-scale substations, especially with some units being only 6 ft. wide and 16 ft. long. This reduces land rental costs and allows freed space to be better utilized.
