Packaged Transformer Substation – Effective Solution for Energy Supply (PTS)

High-quality advanced Packaged Transformer Substations (PTS) are essential for the stable operation of the power system, ensuring a reliable power supply to both industrial facilities and residential areas. A properly configured and installed PTS ensures a stable power supply, efficient distribution of electric power to energy facilities, and safe operation of equipment.

What is a Packaged Transformer Substation (PTS)?

Packaged Transformer Substation (PTS) is a module that includes a power transformer, high-voltage and low-voltage distribution devices, as well as protection and automation systems. All components are installed in a single housing, ensuring quick connection and simplified electrical installation.

Packaged Transformer Substation: Intended Use

This electric device receives electricity from utility companies and converts voltage levels in the AC network. In addition to converting voltage, the substation equipment distributes electricity and redistributes it to the entire power supply system.

Main Elements of a Packaged Transformer Substation

• Power Transformer

Voltage is converted from high to low or vice versa, depending on the needs of the power facility.

• Input High-Voltage Switchgear

It provides power reception, disconnection, switching, and power lines protection.

• Low-voltage distribution panel

It distributes electric power between end users and protects electrical networks.

• Protection and automation system

It controls operating modes, prevents accidents, performs relay protection functions.

• Enclosure (metal or concrete)

It protects electrical equipment from external impacts.

Packaged Transformer Substation: Types

This equipment can be classified according to its design and functional features:

• By method of installation: ground, support, and container.
• By type of enclosure: metal and concrete.
• By designation: for industrial enterprises, residential areas, agricultural and specialized facilities (quarries, construction sites, temporary sites).

What is the Packaged Transformer Substation Used for and Where Is It Installed?

PTS is used to ensure stable and uninterrupted power supply in medium and low voltage networks. Packaged Transformer Substations are installed:

• At industrial enterprises;
• In residential areas and the private sector;
• At construction sites;
• At agricultural facilities;
• As part of power facilities in power supply networks.

The PTS acts as a protection system for power distribution, voltage transformation, and equipment protection against emergency modes.

When is the Installation of a Packaged Transformer Substation the Most Justified?

The use of a packaged transformer substation is the best solution in several practical situations.

Power Supply for Remote or Temporary Facilities

PTS is ideal for construction sites, recreation centers, cottage villages, and other facilities located far from central power grids. These substations provide reliable independent power supply and require minimal maintenance, which is an undoubted advantage for hard-to-reach areas.

Fast Connection of New Residential and Commercial Properties

Packaged Transformer Substations provide uninterrupted power supply in new areas where the power supply infrastructure is not yet fully developed, both during the construction phase and during the subsequent operation of residential buildings.

Modernization of Aging Electrical Distribution Networks

Replacing outdated transformer units with comprehensive PTS equipment significantly improves energy efficiency and increases the overall safety of the power supply system. Outdated equipment often has insufficient capacity to cope with today's electrical loads, is prone to breakdowns, and requires frequent repairs, and all these factors result in power supply issues and increased maintenance costs.

Operating Principle of Packaged Transformer Substations

• The high-voltage line supplies electricity to the input distribution device.
• Subsequently, the voltage is supplied to the power transformer via switching equipment.
• The transformer reduces the voltage to the required level (usually 0.4 kV).
• A low-voltage distribution panel distributes electricity to consumers.

The protection system monitors operating modes and disconnects the transformer substation in case of an accident.
