What is Electric Power Transformer?

Power Transformer Definition

A power transformer is a static device that efficiently transfers electrical energy between circuits without changing the frequency, using electromagnetic induction.

Main Technical Parameters

  • Rated voltage

  • Rated power

  • Rated current

  • Voltage ratio

  • Turns ratio

Voltage Adjustment

Power transformers modify voltage levels to enhance energy efficiency and safety in power transmission and distribution.

Core and Shell Types

  • Step-up and step-down transformers

  • Single-phase and three-phase transformers

  • Two-winding and autotransformers

  • Distribution and power transformers

  • Instrument transformers

  • Oil-cooled and dry-type transformers

  • Core type and shell type transformers

  • Outdoor vs. Indoor Transformers

Types of Power Transformers

Various types, such as step-up, step-down, single-phase, and three-phase, cater to different electrical system requirements.

Power Transformers Advantage

  • To reduce power loss in transmission lines

  • Galvanic Isolation Provided

  • Impedance Matching

  • Voltage Level Adjustment

Applications

Essential in sectors like power generation, transmission, and distribution, power transformers also provide specific voltage levels for diverse applications.

What Is the Working Principle of a Power Plant Boiler?
What Is the Working Principle of a Power Plant Boiler?
The working principle of a power plant boiler is to utilize the thermal energy released from fuel combustion to heat feedwater, producing a sufficient quantity of superheated steam that meets specified parameters and quality requirements. The amount of steam produced is known as the boiler's evaporation capacity, typically measured in tons per hour (t/h). Steam parameters primarily refer to pressure and temperature, expressed in megapascals (MPa) and degrees Celsius (°C), respectively. Steam qua

What is the principle of live-line washing for substations?
Why Do Electrical Equipment Need a "Bath"?Due to atmospheric pollution, contaminants accumulate on insulating porcelain insulators and posts. During rain, this can lead to pollution flashover, which in severe cases may cause insulation breakdown, resulting in short circuits or grounding faults. Therefore, the insulating parts of substation equipment must be periodically washed with water to prevent flashover and avoid insulation degradation that could lead to equipment failure.Which Equipment Is

Essential Dry-Type Transformer Maintenance Steps
Routine Maintenance and Care of Dry-Type Power TransformersDue to their flame-resistant and self-extinguishing properties, high mechanical strength, and ability to withstand large short-circuit currents, dry-type transformers are easy to operate and maintain. However, under poor ventilation conditions, their heat dissipation performance is inferior to that of oil-immersed transformers. Therefore, the key focus in the operation and maintenance of dry-type transformers is controlling the temperatu
