The Mobile Transformers are pre-manufactured and tested in the factory, and come fully assembled and oil-filled, ready for rapid deployment. They can be installed on-site within a matter of hours and can be easily detached from their moving base for specific or extended operations.

The Mobile Transformers from Hitachi Energy are suitable for a wide range of emergency response scenarios and can be shipped to different locations within 230kV and 345kV when installed on a trailer.

Hitachi Energy's Mobile Transformer is a type of mobile substation that is designed to provide a temporary power supply to areas that have experienced a power outage or where power is needed in a remote location. Here are some advantages and functionalities of the Hitachi Energy Mobile Transformer:

Major Functionalities

  • Voltage transformation - The Mobile Transformer is capable of transforming high voltage power to low voltage power or vice versa, allowing it to be used in a variety of applications. 
  • Power distribution - The Mobile Transformer can be used to distribute power to multiple locations or equipment within a site. It includes built-in switchgear and control systems to ensure safe and reliable power distribution. 
  • Temporary power supply - The Mobile Transformer can be used to provide temporary power in situations where the permanent power supply is not available or has been disrupted, such as during a power outage or while a permanent power system is being installed.

Advantages of Mobile Transformer

  • Rapid deployment - The Hitachi Energy Mobile Transformer can be deployed quickly to restore power to areas that have experienced an outage or where temporary power is needed. It can be transported by truck, train, or ship and can be operational within hours of arrival. 
  • Customizable design - The Mobile Transformer can be customized to meet the specific power requirements of a site, including voltage, frequency, and power capacity. This flexibility allows it to be used in a variety of applications, from industrial and commercial sites to remote locations. 
  • Compact size - The Mobile Transformer is designed to be compact, making it easy to transport and install. Despite its small size, it is capable of providing a high level of power output, making it a cost-effective solution for temporary power needs.
  • Reliable operation - he Hitachi Energy Mobile Transformer is designed to operate reliably in a variety of environments and weather conditions. It includes built-in protection features, such as overvoltage and overcurrent protection, to help prevent damage to connected equipment.

Hitachi Energy's Mobile Transformers are available in two different designs: core type and shell type. Here are some details about each design:

Core type design - In this design, the transformer's active parts (i.e., the core and windings) are assembled separately and then installed inside a tank. The core is typically made of laminated sheets of magnetic material, which help to reduce energy losses and improve efficiency. The windings are then wound around the core and connected to the transformer's bushings.

Shell type design - In this design, the transformer's active parts are assembled into a single unit that is enclosed within a shell. The shell is made up of a series of individual steel shells that are welded together to form a single unit. The windings are then installed inside the shell, and the core is placed around the windings. This design offers a compact and robust solution that is ideal for mobile applications.

Hitachi Energy's shell-type design is unique in that it uses a patented configuration of the transformer's active components. This design enables an ultra-compact and durable solution that is well-suited for emergencies and rapid transportation. The shell-type design also offers several advantages over traditional core type designs, including:

  • Compact size - The shell-type design is more compact than traditional core-type designs, which makes it easier to transport and install. 
  • Improved efficiency - The shell-type design reduces energy losses and improves efficiency by minimizing the distance between the windings and the core.
  • Robust construction - The individual shells that make up the transformer's shell are welded together, creating a more robust and durable structure that is better able to withstand the rigors of mobile use.

The Hitachi Energy Mobile Transformer is a versatile and reliable solution for temporary power needs. Its rapid deployment, customizable design, and reliable operation make it a valuable asset for industrial, commercial, and utility applications.
