Automatic load sharing of distribution transformer for overload protection

Area of Science:

• Electrical Engineering
• Power Systems Engineering

Background:

• Distribution transformers are susceptible to damage from overload conditions, leading to reduced efficiency and potential winding failure.
• Overloading causes overheating, which can result in permanent damage and operational downtime.

Purpose of the Study:

• To develop and implement a load-sharing system for protecting distribution transformers against overload.
• To prevent transformer damage by distributing load current across phases.

Main Methods:

• An automated system was designed to manage transformer loads.
• Switches were integrated to automatically connect and disconnect loads based on predefined rules.
• A controller was utilized to implement the load management strategy.

Main Results:

• The developed system successfully shares transformer loads automatically.
• The controller effectively managed load distribution according to established rules.
• Transformer protection under overloaded conditions was achieved.

Conclusions:

• Automated load sharing is an effective method for protecting distribution transformers from overloads.
• The implemented system enhances transformer reliability and operational lifespan.
• Intelligent load management is crucial for power distribution system stability.
