Description

The 22 kV Current Transformer (CT) is a high-performance medium-voltage instrument transformer designed for accurate current measurement, protection, and metering in electrical distribution systems. It is widely used in substations, power utilities, industrial plants, renewable energy projects, and commercial power networks operating up to 22 kV. Manufactured using high-quality insulation materials and precision-engineered cores, the 22 kV CT ensures excellent measurement accuracy, thermal stability, and reliable performance under demanding operating conditions. It safely converts high primary currents into standardized secondary currents (1A or 5A), allowing protective relays, meters, and monitoring equipment to operate efficiently while maintaining electrical isolation. Designed to comply with IS and IEC standards, the transformer offers low maintenance, high dielectric strength, and long service life. Its robust construction and weather-resistant design make it suitable for both indoor and outdoor installations, ensuring dependable operation in harsh environments.
