What Is a 2000kVA Transformer?
UM 2000transformador kVA is an electrical device designed to transfer electrical energy between circuits with a rated capacity of 2000 quilovolt-amperes (kVA), which is equal to:
- 2000kVA = 2MVA
It is commonly used to step down medium voltage (MV) to low voltage (Lv) for end users or step up voltage in power systems.
Key Features:
- High load capacity
- Regulação de tensão estável
- Longa vida útil
- Suitable for continuous operation
How Does a 2000kVA Transformer Work?
The operation of a transformer is based on indução eletromagnética.
Simple Working Process:
- Alternating current flows into the primary winding
- A magnetic field is created in the core
- This magnetic field induces voltage in the secondary winding
- Voltage changes according to the turns ratio
Basic Formula:
- Relação de tensão = Relação de voltas
- A potência permanece quase constante (minus losses)
This simple principle allows efficient transmission of electrical energy over long distances.
Types of 2000kVA Transformers
Different environments require different transformer types. The most common types include:
1. Transformador Imerso em Óleo
- Uses insulating oil for cooling
- Excellent heat dissipation
- Suitable for outdoor installations
- Long lifespan
2. Transformador tipo seco
- Refrigerado a ar, sem óleo
- Safer for indoor use
- Low fire risk
3. Transformador de resina fundida
- Encapsulated windings
- High resistance to moisture and dust
- Ideal for harsh environments
