Voltage measuring transformers are designed to convert high voltage supplied to the primary winding into standardized, safe levels suitable for measuring instruments, protective relays, and automation systems. These devices make it possible to measure electrical network parameters accurately without the need for direct contact with high-voltage components.
Each voltage transformer has a defined rating, which specifies the operating range within which the device ensures maximum measurement accuracy. The primary winding is connected to the high-voltage network, while the secondary winding provides a reduced, standardized voltage output for metering and protection equipment. A properly selected transformer significantly enhances operational safety and ensures stable, reliable measurements.
Alongside classic electromagnetic transformers, optical and digital voltage transformers are becoming increasingly popular, especially in modern digital substations. These advanced technologies offer higher accuracy, improved reliability, and full compatibility with automated control systems. You can order modern voltage transformers of various types on the “Stalev-Energo” website.
The primary purpose of voltage transformers is to provide electrical isolation between measuring instruments and high-voltage circuits, as well as to reduce voltage to standardized values suitable for accurate measurement and safe operation.
The application range of voltage transformers is broad. They are used in:
By using voltage transformers, the safety of electrical installations is significantly improved, measurement accuracy is increased, and reliable network protection during fault conditions is ensured. Modern voltage transformers can be used both in industrial facilities and in energy distribution systems of any scale.
