If you are looking for a durable and cost-effective solution, this guide will help you understand everything about the 2000transformator kVA, including specifications, working principles, aplikasi, and how Grup DOS can support your project with professional manufacturing and global supply.
What Is a 2000kVA Transformer?
A 2000transformator kVA is an electrical device designed to transfer electrical energy between circuits with a rated capacity of 2000 kilovolt-ampere (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.
Fitur Utama:
- Kapasitas beban tinggi
- Regulasi tegangan stabil
- Umur panjang
- Suitable for continuous operation
How Does a 2000kVA Transformer Work?
The operation of a transformer is based on induksi elektromagnetik.
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:
- Rasio tegangan = Rasio putaran
- Kekuasaan tetap hampir konstan (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. Trafo Terendam Minyak
- Uses insulating oil for cooling
- Excellent heat dissipation
- Suitable for outdoor installations
- Umur panjang
2. Transformator Tipe Kering
- Berpendingin udara, tidak ada minyak
- Safer for indoor use
- Low fire risk
3. Transformator Resin Cor
- Encapsulated windings
- High resistance to moisture and dust
- Ideal for harsh environments
