Dry-Type Transformers

Dry-Type Transformers With the development of modern cities, fire and explosion-proof requirements have been introduced for distribution rooms, especially those in high-rise buildings and buildings with high fire ratings, in accordance with relevant fire safety regulations. Dry-type transformers,... Read More

Why do we need reactive power compensation?

Why do we need reactive power compensation? And its principles and forms! Power factor is measured for different loads. In the previous era of direct current, there was no such thing as power factor. At that time, the power factor was 1. Later, Tesla brought us into the era of alternating current... Read More

Dry-Type Transformer Structure, Cooling Methods, Installation, and Commissioning

Dry-Type Transformer Structure, Cooling Methods, Installation, and Commissioning Introduction: Dry-type transformers are power transformers whose core and windings are not immersed in insulating oil and instead utilize natural or air cooling. As a relatively new type of power distribution equipme... Read More

Types of Electrical Transformers

Types of Electrical Transformers Besides varying in size, transformers can be categorized into different types to meet energy needs. Voltage Transformers Voltage transformers can also be called “potential transformers.” They step down a large voltage and operate in parallel with the i... Read More

How do power transformers work?

How do power transformers work? Power transformers operate based on Faraday’s law. Simply put, they use electromagnetic induction to connect two circuits, transferring current from one circuit to the other. As mentioned earlier, the voltage may sometimes increase or decrease during the tran... Read More

A Brief Description of the Functions of Each Type of High-Voltage Panel

A Brief Description of the Functions of Each Type of High-Voltage Panel 1. Power Incoming Panel: This panel receives the main power supply (main incoming panel), housing the main circuit breaker. 2. Outgoing Panel: This panel houses the outgoing switchgear for the distribution system, housing dow... Read More

What are the structural features of gas-filled cabinets?

What are the structural features of gas-filled cabinets? Globally, high-voltage gas-filled cabinets have experienced rapid development in recent years, with their use increasing dramatically. What is a gas-filled cabinet? A gas-filled cabinet is a type of switchgear that seals high-voltage compon... Read More

Transformer Cabinet

Transformer Cabinet: This is a key piece of equipment in power plants and substations. It serves two main functions: meeting user voltage requirements and reducing power losses during transmission. A transformer is an electrical device that operates on the principle of electromagnetic induction. ... Read More

The main functions of the DC power supply within the high-voltage cabinet

The main functions of the DC power supply within the high-voltage room are: 1. It provides power to the closing mechanism of the high-voltage switch. For example, electromagnetic (CD) closing mechanisms require high DC currents, while spring-charged (CT) closing mechanisms do not, requiring only ... Read More

The functions of the PT cabinet

The functions of the PT cabinet in high-voltage switchgear are: 1. Voltage measurement, providing a voltage circuit for measuring meters 2. Providing operating and control power 3. Installing overvoltage protectors for each busbar section 4. Meeting relay protection requirements, such as busbar i... Read More

Correct use of high-voltage switchgear grounding switch

The grounding switch in high-voltage switchgear is a mechanical grounding device used for safety maintenance. During electrical equipment maintenance, it grounds potentially energized circuit breakers or busbars to prevent induced voltage from harming maintenance personnel. The typical operation ...
