Overview

The Nanjing three-phase ammeter and three-phase three digital current intelligent meter are designed according to China's requirements for the operation and monitoring of power equipment. Users can adjust CT parameters through panel buttons, intuitively display the system's primary current, and the digital tube displays the three-phase current value at the same time. The display is clear and beautiful, and can directly replace traditional analog pointer meters. It has an analog signal transmission output function, which is convenient to connect with remote RTUs. It is a high-performance automation instrument suitable for modern power supply and distribution systems such as industrial and mining enterprises, civil buildings, and building automation.
