current transformer A current transformer (CT) is an electrical transformer that measures alternating current (AC) and produces a proportional reduced current for measurement, monitoring, and protection purposes. Here's a comprehensive overview: Key Features: 1. Measurement: CTs measure AC currents in power systems, transmission lines, and distribution networks. 2. Step-down: They step down high currents to lower values, making it safe for measurement and monitoring. 3. Isolation: CTs provide electrical isolation between the primary and secondary circuits. 4. Accuracy: They offer high accuracy and precision in current measurement. current transformer Manufacturer In Vadodara current transformer Manufacturer In Gujarat current transformer Manufacturer In India
