1.Product profile
The power measurement and control terminal is our company's new generation of high-end products. This terminal has both conventional high-precision measurement and comprehensive power quality monitoring functions. The terminal is mainly used in the field of power information acquisition for three-phase power networks with frequencies ranging from 45 to 65Hz. It can measure all electrical parameters, temperature, etc. in the power grid and exchange data with the upper computer through communication. Users can set the internal parameters of the product according to the actual situation on site, which is convenient to use, easy to operate, and has high accuracy; Especially suitable for real-time online power quality detection applications and railway power supply remote control systems. The supporting AI temperature sensing relay adopts wireless communication to connect the measurement and control terminal, with a built-in wireless module for forwarding data. It can be used in conjunction with our company's intelligent gateway or color screen power AI acquisition and control terminal measurement and control products. As an advanced intelligent digital power grid front-end acquisition component, it is widely used in various control systems, substation automation systems, and distribution automation systems. It has the characteristics of easy installation, simple wiring, easy maintenance, and small engineering quantity, and can flexibly network with various communication software.
