Potential Transformer
Potential Transformer (PTs), also known as Voltage Transformer, are instrument transformer designed to reproduce the primary voltage on the secondary side in a proportional and reduced form suitable for measurement and protection equipment.
They provide electrical isolation between the high-voltage power system and the measuring or protection devices, ensuring safety and accurate system monitoring.
Our Potential Transformer are specially designed for metering and protection applications and are manufactured in accordance with IS 16227 / IEC 61869 standards, ensuring compliance with international quality and performance requirements.
