What is Transformer Cooling System?

Transformer Cooling System Definition

A transformer cooling system is defined as methods used to dissipate heat generated in transformers to prevent damage and ensure efficiency.

Components of the cooling system

Radiators or Coolers

Provides a large area of heat exchange surface, so that the heat in the oil can be transferred to the surrounding air or water.

Fans

Accelerate air flow and improve heat dissipation efficiency.

Oil Pumps

In a forced oil circulation system, it is used to push the oil to circulate inside and outside the transformer.

Coolers

In water-cooling systems, it is used to transfer heat from oil to water.

Control device

Including temperature controller, flow controller, etc., for monitoring and regulating the operation of the cooling system.

Type of cooling system

ONAN Cooling

ONAN cooling uses natural oil and air circulation to cool the transformer, relying on convection for heat dissipation.

ONAF Cooling

ONAF cooling employs fans to blow air over the transformer, enhancing heat dissipation by forced air circulation.

ODAF Transformer

The ODAF (Oil Directed Air Forced) transformer uses directed oil flow and forced air to cool high-rating transformers efficiently.

ODAF Transformer

The ODAF (Oil Directed Air Forced) transformer uses directed oil flow and forced air to cool high-rating transformers efficiently.

OFAF Cooling

OFAF cooling combines oil pumps and air fans to circulate oil and cool the transformer quickly and efficiently.

What is Automatic Voltage Regulator?
What is Automatic Voltage Regulator?
An automatic voltage regulator is employed to regulate voltage, converting fluctuating voltages into a constant one. Voltage fluctuations mainly stem from variations in the load on the supply system. Such voltage variations can damage the equipment within the power system. These fluctuations can be mitigated by installing voltage - control equipment at various locations, such as near transformers, generators, and feeders. Multiple voltage regulators are often placed throughout the power system t

What is Static Voltage Regulator?
Types of Static Voltage RegulatorThe static voltage regulator is superior to electromechanical regulators in respect of the accuracy of control, response, reliability and maintenance. The static voltage regulator is mainly classified into two types. They are;Servo Type Voltage RegulatorMagnetic Amplifier RegulatorThe types of static voltage regulator are described below in details;Servo Type Voltage RegulatorThe main feature of the servo type voltage regulator is the use of the amplidyne.

What is Arc Extinction Circuit Breaker?
What is Arc Extinction Circuit Breaker?
When the current-carrying contacts of a circuit breaker separate, an arc forms and persists briefly after contact separation. This arc is hazardous due to the heat energy it generates, which can produce explosive forces.A circuit breaker must extinguish the arc without damaging equipment or endangering personnel. The arc significantly influences the breaker’s performance. Interrupting aDC arcis inherently more challenging than anAC arc. In an AC arc, the current naturally reaches zero duri

Air Break Circuit Breaker
Air Break Circuit Breaker
In an air break circuit breaker, the arc is initiated and extinguished in substantially static air as the arc moves. These breakers are used for low voltages, generally up to 15 kV, with rupturing capacities of 500 MVA. As an arc-quenching medium, air circuit breakers offer several advantages over oil, including:Elimination of risks and maintenance associated with oil use.Absence of mechanical stress caused by gas pressure and oil movement.Elimination of costs from regular oil replacement due to
