Voltage Transformers must convert transmission class voltages to standardized low and easily measurable values, which will be used for metering, protection, and control of the high voltage system. As such, the need for accurate and reliable voltage transformation is essential.

       ♦ Capacitive Voltage Transformers (CVTs)

(CVTs) have been widely used within transmission power systems for applications ranging from high-voltage to ultra-high-voltage. CVTs are primarily used for voltage measurement, providing voltage signals to metering units, protection relay devices, and automatic control devices. Additionally, Capacitor Voltage Transformers serve as a coupling capacitor for coupling high-frequency power line carrier signals to the transmission line.

       ♦ Inductive Voltage Transformers (IVT)

(IVT), are used for voltage metering and protection in high voltage network systems. They transform the high voltage into low voltage adequate to be processed in measuring and protection instruments secondary equipment, such as relays and recorders).
