Mobile Transformer Substations on Skids for Georad DOO

Elektrovat is proud to present one of our latest projects in collaboration with Georad DOO. This project involves the development and implementation of mobile transformer substations on skids, designed to supply power to consumers. The project includes two versions of transformer substations with different transformer capacities – one of 400 kVA and three of 250 kVA – providing flexibility and reliability in powering remote locations.

The goal of the project is to ensure stable and reliable power supply in challenging locations such as well lines, where temporary and mobile solutions are required. These transformer substations are designed for easy transportation, installation, and use in various terrains, including sandy and soil grounds, without compromising power quality.

Technical Specifications

Substation 1: 400 kVA

  • Primary Voltage: 6 kV

  • Secondary Voltage: 0.4 kV

  • Transformer Capacity: 400 kVA

  • Transformer Coupling: Dyn5

Substation 2: 250 kVA

  • Primary Voltage: 6 kV

  • Secondary Voltage: 0.4 kV

  • Transformer Capacity: 250 kVA

  • Transformer Coupling: Dyn5

Both substations utilize oil-cooled transformers with natural air circulation and are equipped with Buchholz relays and contact thermometers to protect against overloading and internal faults.

Construction:

  • The mobile transformer substations are mounted on skids, allowing easy movement and transportation. The container structure is made of steel tubes and plates, with hot-dip galvanizing for corrosion protection. The skids are 620 mm high, equipped with openings for cable pulling, providing stability on difficult terrain.

    The container dimensions provide ample space for housing all key components:

    • Transformer compartment (TB)
    • Medium voltage switchgear block (MV)
    • Low voltage block (LV)

    All sections are physically separated, and the equipment is easily accessible, allowing for simple handling and maintenance without the need to enter the substation, except for low voltage equipment access.

Medium Voltage Block (MV):

  • Both versions of the substations use a medium voltage switchgear block with SF6 technology in Schneider Electric’s RM6 Ring Main Unit systems. The medium voltage block consists of three cells: feeder, incoming, and transformer cells, designed to operate at 6 kV with a rated current of 630A and a breaking capacity of 25kA.

Low Voltage Block (LV):

  • The low voltage block is housed in a separate switchboard with protective breakers and equipment for measuring electrical parameters. The breakers are equipped with microprocessor protection units (Micrologic), providing protection against short circuits and overloading. Current and power measurements are made possible through the PM2120 multimeter, while protective breakers are installed to allow manipulation without direct contact with live equipment.

Protection and Grounding:

  • Both substations are equipped with protection systems, including:

    • Buchholz relay – for internal fault protection within the transformer.
    • Contact thermometer – for monitoring transformer temperature and preventing overheating.

    Grounding for the substations is done on-site, connecting all metallic parts to the potential equalization busbar. This ensures operator safety and the stable operation of the entire system.

Cooling and Lighting:

  • Natural air circulation through ventilation openings cools the transformer without the need for additional cooling systems. Lighting is automatically activated when the substation doors are opened, enabling uninterrupted work even in low-visibility conditions.

The project for mobile transformer substations on skids for Georad DOO stands out as an innovative solution for temporary power supply in remote and hard-to-reach areas. With flexibility in capacity (250 kVA and 400 kVA), these substations provide stable power, easy handling, reliable protection, and durability, all with minimal logistical challenges.

Elektrovat is proud to be part of this project and continues to contribute to the development of energy infrastructure through innovative and adaptable solutions.
