This document introduces the features and characteristics of the E series multifunction power meter produced by Yangzhou Xinling Electrical Instrument Co., Ltd. The meter can measure various common power parameters and electrical energy, and has digital communication and electrical energy pulse output functions. It is suitable for grid front-end acquisition, control systems, energy management systems, substation automation, distribution network automation, residential power monitoring, industrial automation, smart buildings, etc.

ZBWKG-3000 High Voltage Reactive Power Compensation Controller adopts 16-bit single-chip microcomputer chip, AC sampling technology, LCD Chinese display, quadrant analysis and other technologies, realizes real-time data collection, communication, power statistics, historical data storage, fault alarm, grid harmonic analysis, reactive power compensation and other functions, and can be directly connected to the computer for online operation. The high-voltage reactive power compensation controller can control the automatic switching of the reactive power compensation capacitor group according to the parameters of the grid. Make the capacitor work in the best condition, ensure that the voltage qualification rate meets the requirements, effectively reduce the reactive power loss and keep the system power factor in a high range.

The electric regulating valve of ZDSJP (M) series produced by Anhui Tiankang (Group) Co., Ltd. has the characteristics of small size, light weight, simple wiring, large flow rate and high adjustment accuracy. It is widely used in industrial process automatic control systems in the electric power, petroleum, chemical industry, metallurgy, environmental protection, light industry, teaching and scientific research equipment industries.
