Understanding the 3000 kVA Transformer
A 3000 kVA transformer is a high-capacity power transformer designed for large-scale industrial, utility, or infrastructure projects. With the ability to handle large electrical loads, it ensures safe voltage regulation and efficient energy distribution in medium to high voltage systems.
This transformer plays a crucial role in power systems by stepping down or stepping up voltage levels based on specific application requirements. These units are typically oil-immersed or dry-type, depending on the installation environment and performance expectations.
Technical Specifications of a 3000 kVA Transformer
Here are the most common and critical specifications associated with a 3000 kVA transformer:
- Rated Power: 3000 kVA
- Primary Voltage: 11kV / 22kV / 33kV / customizable
- Secondary Voltage: 400V / 415V / customizable
- Frequency: 50Hz or 60Hz
- Cooling Type: ONAN (Oil Natural Air Natural), ONAF (Oil Natural Air Forced), or AN (Air Natural) for dry-type
- Phase: 3 Phase
- Vector Group: Dyn11 / Yyn0 / others
- Impedance: Typically 6.25% to 8%
- Insulation Class: Class A or F (Dry), Class A (Oil)
- Cooling Medium: Mineral Oil or Dry Resin
- Standard Compliance: IEC 60076 / ANSI / GB / IEEE
Customization Options
Most 3000 kVA transformers are available with custom parameters such as tap changer range (±2×2.5% / ±5%) and advanced cooling options. They can also be fitted with smart monitoring systems and environmental sensors for predictive maintenance.
Applications of a 3000 kVA Transformer
These transformers are essential for operations that require high voltage and high current capacity. Below are key application areas:
- Industrial Plants – Steel, automotive, cement, chemical industries.
- Commercial Complexes – Shopping malls, business parks, hotels.
- Hospitals and Universities – For power reliability and backup systems.
- Renewable Energy Farms – Wind and solar energy distribution stations.
- Utilities and Substations – As step-down or step-up transformers for grid infrastructure.
3000 kVA Transformer Price Factors
The price of a 3000 kVA transformer can vary greatly based on several factors. Understanding these influences helps in better budgeting and procurement:
1. Core Materials
- High-grade silicon steel or amorphous metal affects cost.
2. Cooling System Type
- ONAN and ONAF are more economical than OFAF or forced air systems.
3. Insulation & Protection
- Advanced insulation materials and smart features raise the cost.
4. Compliance & Certifications
- IEC, IEEE, and ISO certification requirements add to the price.
5. Logistics & Installation
- Shipping, handling, and installation vary by region and complexity.
Estimated Price Range: Depending on the above parameters, a 3000 kVA transformer price typically ranges between $35,000 – $65,000 USD. Contact the manufacturer for an accurate quote based on your project needs.
