Potential Transformers for Self-Powered Control in Medium Voltage Equipment

Types of insulation for control potential transformers

• Oil-filled potential transformer: Ideal for applications requiring high insulation capacity and stability under severe operating conditions.
• Resin-Encapsulated Solid Potential Transformer: Offers excellent protection against moisture and contaminants, ensuring a long service life and reducing the need for maintenance.

Advantages of Self-Powering for Remote Control. The integration of potential transformers for self-powering controls, relays, and radios into medium-voltage equipment significantly simplifies the necessary electrical infrastructure. This solution eliminates the dependence on external power sources for equipment operation, which leads to:

• Complexity Reduction: Simplifies system design by eliminating additional components required for power delivery.
• Reduced Installation Time: Streamlines the deployment process thanks to its integrated configuration, facilitating faster start-up.
• Reduced Costs: Reduces both installation and maintenance costs by minimizing the number of components and the technical interventions required.

Applications of Potential Transformers

• Power Reclosers: Provide a reliable power source for reclosers in medium voltage systems, crucial for automatic recovery operations and improved system reliability.
• Self-powered three-phase disconnectors: Facilitates the autonomous control and operation of disconnectors, essential for the effective and efficient management of electrical networks.

Our Power Transformers are designed to offer maximum efficiency and reliability, improving power quality management and optimizing the overall performance of the electrical system. These transformers are key solutions for modernizing and improving medium-voltage infrastructure.
