Power transformers TMG

What is a TMG transformer?

TMG transformer is a high-efficiency three-phase oil transformer designed to transform electricity in medium and high voltage networks (6 kV, 10 kV, 20 kV, 35 kV) to the consumption level (0.4 kV, 0.69 kV). These transformers are used in industry and distribution networks, providing stable and safe voltage reduction for various objects.

Oil-cooled TMG transformers are ideally suited for operation in moderate climate conditions (UHL1) and ensure long-term and reliable operation in open and closed electrical installations. Thanks to high quality materials and strict control at all stages of production, TMG transformers guarantee high energy efficiency, durability and low operating costs.

These devices are particularly in demand in large industries, power generation, and power distribution systems where high power and stable operation are required.

TMG transformer parameters from Evernew Transformer: technical specifications and explanations

General characteristics of Transformer TMG

TMG transformer is a three-phase oil transformer with natural cooling, designed for operation in electrical networks with a frequency of 50 Hz. These transformers are effective in electric energy conversion (voltage reduction or increase) and provide stable power supply for consumers in various industries.

Operating conditions of TMG Transformer

The TMG transformer has a wide operating temperature range, making it versatile for various climatic conditions. The optimum ambient temperature for its operation is from -45°C to +40°C, while for operation in colder regions it is possible to extend the range to -60°C. These transformers are ideally suited for moderately cold climates and provide reliable operation in such conditions.

  • Installation height: up to 1000 meters above sea level.
  • Environment: it is recommended to avoid operation in areas with conductive dust, corrosive or explosive gases, or in areas with high concentrations of steam or chemically active substances.
  • Vibration and shock: TMG transformers are not designed for operation under severe vibration or shock loads.

Design and features of TMG Transformer

The TMG transformer consists of high quality components ensuring its durability and high efficiency:

  • Case: welded metal construction with elliptical or rectangular body. Strong connections and tightness are achieved by using high quality materials such as oil resistant rubber products.
  • Magnetic system: made of cold-rolled electrical steel, which contributes to minimal transformer losses and increased reliability.
  • High and low voltage windings: made as block coils of copper or aluminum for excellent conductivity and durability.
  • Cooling: naturally cooled, which helps to reduce operating costs and extends the service life of the unit.

Standards and certification

The TMG transformer complies with international quality standards including GOST, CE and UL. It meets the climatic conditions of GOST 15150, categories U1 and UHL1, making it an ideal choice for use in a wide range of temperatures and operating conditions.

Main parameters of TMG transformer:

  • Power: 16 kVA to 2500 kVA
  • Voltage: high - 6 kV, 10 kV, 20 kV, 35 kV; low - 0.4 kV, 0.69 kV, 3.15 kV, 6.3 kV, 10.5 kV.
  • Defense: protection class IP00.

Long service life

TMG transformer is designed for a service life of up to 30 years under the operating conditions, which makes it a profitable investment for enterprises and power supply companies.

Characteristics and principle of operation of TMG transformer

The TMG transformer is equipped with a hermetically sealed tank, which effectively protects the process fluid from the external environment. It consists of two windings, which can increase or decrease the voltage depending on the connected characteristics. The principle of operation of the transformer is based on mutual induction, where the voltage is transmitted between the two windings, changing its characteristics depending on the properties of these windings.

Main ingredients:

  • Frame: maintains the structure of the transformer, ensuring its stability.
  • Winding terminals: are used for current input and output, connecting the transformer to the electrical network.
  • Core: made of high quality steel, is a key element for electromagnetic energy transfer.
  • Oil tank: hermetically sealed design that protects transformer oil from contamination and ensures long-term operational stability.
  • Control and measuring devices: for continuous monitoring of the transformer's operation to ensure safe operation.
  • Iron in the winding: creates an electromagnetic field that allows voltage to be transmitted through a change in current.

TMG transformers have a significant power reserve, while their nominal parameters are usually not lower than the parameters of the network into which they are installed, which ensures efficient operation of the transformer. At the same time, the transformer characteristics are not excessive in order to avoid unnecessary energy losses and achieve optimum operating efficiency.

Quality Management - Evernew Transformer

Evernew Transformer is known for its strict quality management standards and high quality products. We follow a two-stage quality control process that ensures that each transformer is thoroughly inspected and tested before shipment, ensuring that it performs efficiently and consistently under a variety of operating conditions.

Stage One: Quality control of materials and components

Evernew Transformer carefully selects all materials used in the manufacture of transformers to ensure they meet international standards. Our quality control team carefully inspects key materials such as copper wires, insulation materials, transformer oil, silicone steels and other components to ensure the longevity and reliability of TMG transformers. We also monitor every stage of production to ensure that all parts meet design requirements.

Stage Two: Acceptance Testing and Full Inspection

Each transformer manufactured in our factory undergoes extensive inspection and testing to ensure that its performance meets international standards. The main parameters tested include:

  • Winding resistance measurement: to verify that the resistance corresponds to the design values, ensuring low energy losses.
  • Transformer ratio measurement: to ensure the accuracy of the voltage conversion.
  • Measuring winding connections: check that the windings are correctly connected to avoid short circuits.
  • Short-circuit voltage measurement: to test the short-circuit stability of the transformer.
  • Measurement of idle losses: to evaluate the energy efficiency of a TMG transformer under no-load conditions.
  • Insulation dielectric strength testing: for testing the insulation characteristics at high voltage.
  • Oil breakdown voltage measurement: to test the oil's ability to resist breakdown.
  • Noise measurement: to verify that the transformer complies with environmental and noise regulations.
  • Thermal stability testing: check transformer operation at high temperatures and long-term loads.
  • Tightness check: to prevent oil contamination and keep the inside of the unit clean.
  • Vibration testing: to test the resistance of the transformer to mechanical effects and vibrations during transportation and operation.
