Types of Connections Used in Three-Phase Transformers
In a star-star connection, the three phases of a transformer are connected to a common point, called the star point. This connection offers a number of advantages, including reduced energy losses and the ability to ground the transformer.
Advantages of star-star connection
The star-star connection offers a number of advantages over other types of connections, including:
- Provides a neutral point for grounding.
- Reduces the phase voltage on both the primary and secondary sides.
- Reduces leakage current losses.
Disadvantages of star-star connection
The star-star connection also has some disadvantages, including:
- Does not provide complete isolation between phases.
- The short-circuit current is higher than other types of connections.
Applications of star-star connection
The star-star connection is used in a variety of applications, including:
- Power transmission
- Power distribution
- Electrical equipment power supply
A delta-star connection is a type of phase connection used in transformers. In this type of connection, the ends of each phase of the primary are connected together to form a delta, while the ends of each phase of the secondary are connected to a common point, called the neutral.
Advantages of delta-star connection
The delta-star connection offers a number of advantages over other types of connections, including:
- Provides complete isolation between phases.
- The short-circuit current is lower than other types of connections.
Disadvantages of delta-star connection
The delta-star connection also has some disadvantages, including:
- Does not provide a neutral point for grounding.
- The phase voltage is higher than other types of connections.
Applications of delta-star connection
The delta-star connection is used in a variety of applications, including:
- Powering electrical equipment sensitive to overvoltages.
- Short-circuit protection.
