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.

Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
Cost Differences and Performance Comparison of 35kV New Energy Transformers Based on Dry-Type, Mineral Oil, and Vegetable Oil
For users, when purchasing a 35kV new energy transformer, choosing between dry-type, mineral oil-filled, or vegetable oil-filled types involves multiple considerations. These include user habits, maintenance-free performance, safety and fire resistance, volume and weight, among others. However, cost differences are undoubtedly one of the most crucial factors.To illustrate the issue intuitively, this paper selects a three-level energy efficiency dual-winding new energy transformer with a rated ca

What is the connection group of a transformer?
What is the connection group of a transformer?
Transformer Connection GroupThe connection group of a transformer refers to the phase difference between the primary and secondary voltages or currents. It is determined by the winding directions of the primary and secondary coils, the labeling of their start and end terminals, and the connection mode. Expressed in a clock-like format, there are 12 groups in total, numbered from 0 to 11.The DC method is commonly used to measure the transformer's connection group, mainly to verify whether the con

What is the sequence for powering down the transformer?
What is the sequence for powering down the transformer?
The sequence for shutting down a main transformer is as follows: when de-energizing, the load side should be shut down first, followed by the power supply side. For energizing operations, the reverse order applies: the power supply side is energized first, then the load side. This is because: Energizing from the power supply side to the load side makes it easier to identify the fault range and take prompt judgment and handling measures in case of a fault, preventing the fault from spreading or e

What are the methods for switching operations of station transformers?
Let's take an auxiliary power system with two station transformers as an example. When one station transformer needs to be out of service, there are two operation methods: non-interruptive power supply and instantaneous power interruption. Generally, the method of instantaneous power interruption on the low-voltage side is preferred.The operation method for instantaneous power interruption on the low-voltage side is as follows:Open the 380V power incoming circuit breaker of the corresponding sec
