Voltage Transformers
Voltage transformers, also known as potential transformers (PTs) or voltage instrument transformers, play a crucial role in electrical power systems. These devices are designed to accurately and safely transform high voltage levels to lower, more manageable values for measurement, protection, and control purposes. Voltage transformers ensure the reliable and precise monitoring of voltages, allowing for effective operation and maintenance of power grids. They provide isolation and step-down functions, delivering reduced voltages to instruments and protective relays while maintaining proportional accuracy. With their ability to withstand high voltage levels and deliver accurate readings, voltage transformers are indispensable components in modern electrical infrastructure, ensuring the efficient and secure distribution of electricity.
