In modern power systems, accurate measurement of electrical parameters is the foundation of safe operation, effective monitoring, and reliable automation. Among the key components that ensure precision is the Measuring Voltage Transformer. These specialized transformers are designed to convert high-level AC voltage signals into low-level AC voltage signals, making them suitable for safe handling and accurate processing in electronic circuits. With advanced microprocessor-based applications and long-term stability, Tianrui measuring voltage transformers play an indispensable role in power distribution automation and smart grid systems.

What Are Measuring Voltage Transformers

A Measuring Voltage Transformer is an instrument transformer that scales down high-voltage signals to standardized, lower levels suitable for measurement, protection, and control. High-voltage systems—often reaching thousands of volts—cannot be directly connected to measuring instruments or control circuits due to safety risks and hardware limitations.

By converting these voltages into manageable levels, measuring voltage transformers enable precise and safe monitoring of electrical quantities. They also ensure the isolation of sensitive equipment from high-voltage circuits, reducing risks for both operators and systems.

Key Functions of Measuring Voltage Transformers
