HYB-R3 is a high-performance three-phase reactive power transmitter launched by Heyi Electric's B series for industrial power quality monitoring and energy efficiency optimization management. This product is dedicated to accurately monitoring the reactive power components in three-phase power systems and converting them into standard analog signals, providing core and reliable data support for key applications such as reactive power compensation, power factor correction, and power quality analysis in the power grid.
HYB-R3 three-phase reactive power transmitter is a professional instrument designed to meet the high requirements of reactive power monitoring in modern power systems. It is based on the mature technology of Heyi Electric in the field of current (HYB-A3) and voltage (HYB-V3) sensing, integrating advanced real-time computing chips, which can accurately measure the total reactive power in three-phase AC systems. The working principle of the product is to connect three voltage and three current signals, perform real-time calculations based on the mathematical model of reactive power, and accurately convert the calculation results into standard DC signals (such as 0~20mAdc, 4~20mAdc, 0~5VDC, 0~10Vdc) for output. Its core features fully inherit the genes of B-series products: 1. Accurate measurement: By using high-precision signal acquisition and processing technology, precision measurement of 0.5% or higher can be achieved, ensuring the reliability of reactive power data, which is the basic guarantee for power quality control. 2. Stable and reliable: Inheriting the all-round electrical isolation design between input, output, power supply, and housing, it has strong insulation performance and can effectively resist the interference of complex electromagnetic environment on site, ensuring long-term stability of operation. 3. Wide adaptability: Supports wide range power input (AC/DC 80~270V), adopts compact design and standard 35mm DIN rail installation method, suitable for integration of various industrial distribution cabinets and automation control cabinets. 4. Signal consistency and high load capacity: It has the same signal output specifications and installation interfaces as HYB-A3, HYB-V3, and HYB-W3, which facilitates system integration. Capable of high overload capacity and adapting to complex working conditions with dynamic changes in reactive power. As a professional sensor used for calculating and controlling reactive power in the system, HYB-R3 plays a key role in improving grid stability, power factor, reducing line losses, and avoiding energy fines.

Application scenarios
The HYB-R3 reactive power transmitter, with its dedicated performance, is an indispensable device for solving industrial, commercial, and grid reactive power management and power quality problems. It is mainly used in: 1. Reactive power compensation and power factor correction system: As the core front-end sensing unit of Static Var Generator (SVG/SVC) and Intelligent Capacitor Switching Controller (TSC), it provides real-time reactive power signals to achieve automatic, accurate, and fast compensation of power factor, effectively reducing line losses and energy costs. Used to monitor the power factor level of low-voltage distribution cabinets in factories, workshops, or buildings, providing key data for energy efficiency management. 2. Power system and grid operation and maintenance: In power plants, substations, and distribution networks, it is used to monitor the distribution of reactive load in different sections or feeders, help dispatchers optimize the voltage level and reactive power flow of the power grid, and improve the stability and economy of the transmission and distribution network. Used to monitor the reactive power output of power equipment (such as transformers, generators) and ensure their operation within the optimal performance range. 3. Industrial manufacturing and heavy load scenarios: Applied to production lines with concentrated inductive loads such as large motors, welding equipment, rolling mills, and lifting equipment, real-time tracking of the reactive power components generated during operation provides a basis for local compensation or process optimization, avoiding low power factor in the main distribution system. In high-energy consumption facilities in industries such as metallurgy and chemical engineering, it is used to measure the actual energy utilization rate of the system. 4. Monitoring of renewable energy grid connection: At the grid connection point (PCC) of wind and photovoltaic power plants, monitor the reactive power injected or absorbed into the grid to ensure compliance with grid specifications and provide critical inputs for the voltage support control strategy of the system. 5. Railway power supply system: The railway traction power supply system (especially using AC-DC-AC technology) is a typical scenario of reactive load fluctuations. HYB-R3 can be used to monitor reactive power changes in substations or traction substations, guide the switching and regulation of reactive power compensation devices (such as railway SVC), and ensure power supply quality and reliability. 6. Research, testing, and energy efficiency evaluation: As a peripheral sensor for professional testing instruments or laboratory equipment, it conducts power characteristic tests on motors, transformers, and nonlinear loads to obtain reactive power time curves for product performance evaluation or fault analysis.
