Five Different Sizes of Transformers Commonly Used by Tanesco

Tanesco (Tanzania Electric Supply Company) uses various sizes of transformers in different applications. While the specific models and sizes may vary based on project requirements and standards, the following are some commonly used transformer sizes in Tanesco's distribution and transmission networks:

1. Small Distribution Transformers

  • Capacity: 10 kVA to 50 kVA

  • Usage: Primarily used in residential areas, small commercial buildings, and rural regions.

  • Features: Compact size, easy installation, suitable for low-voltage distribution networks.

2. Medium Distribution Transformers

  • Capacity: 100 kVA to 500 kVA

  • Usage: Widely used in urban residential areas, commercial zones, and industrial areas.

  • Features: Provide medium-capacity power supply, suitable for medium-voltage distribution networks.

3. Large Distribution Transformers

  • Capacity: 630 kVA to 1000 kVA

  • Usage: Used in large commercial buildings, factories, and industrial parks.

  • Features: Provide high-capacity power supply, suitable for high-voltage distribution networks.

4. Transmission Transformers

  • Capacity: 1000 kVA to 10000 kVA

  • Usage: Used in transmission networks to connect power plants and distribution networks.

  • Features: Provide large-capacity power transmission, suitable for high-voltage transmission lines.

5. Special Purpose Transformers

  • Capacity: Customized based on specific needs

  • Usage: Used for special applications such as railway power supply, mining power supply, etc.

  • Features: Designed according to specific application requirements, may have special protection and performance features.

Common Transformer Size Examples

  • 10 kVA: Suitable for small residential and commercial buildings.

  • 50 kVA: Suitable for medium-sized residential areas and small commercial zones.

  • 100 kVA: Suitable for urban residential areas and small industrial zones.

  • 630 kVA: Suitable for large commercial buildings and industrial parks.

  • 1000 kVA: Suitable for large industrial zones and transmission networks.

Summary

Tanesco uses transformers of different capacities and sizes based on various application and demand scenarios. Small distribution transformers are primarily used in residential and small commercial buildings, medium distribution transformers are suitable for urban and industrial areas, and large distribution transformers and transmission transformers are used for high-capacity power transmission and distribution. Special purpose transformers are customized to meet specific application requirements.

What tests are required for dry-type transformers?
What tests are required for dry-type transformers?
1 Pre - commissioning InspectionAs a front - line tester, before formally commissioning a dry - type transformer, I need to carry out a comprehensive and systematic inspection. First, I conduct a visual inspection of the transformer body and its accessories, carefully checking for mechanical damage or deformation. Then, I check whether the leads of the high - and low - voltage windings are firmly connected and whether the bolt tightening torque meets the standard requirements (usually 40 - 60N&m
