CA 8343 – Class A Three-Phase Power Analyzer
The CA 8343 is a Class A power quality analyzer from the Qualistar range by Chauvin Arnoux, France.
The device is designed for the analysis, maintenance, and monitoring of industrial installations—ranging from low to high voltage, as well as engineering systems with significant electrical consumption: power supply and low-voltage systems in industrial, administrative, commercial, and residential facilities (e.g., shopping centers, hospitals, offices, schools, etc.); installations featuring high-power electrical loads, such as HVAC systems, laser processing equipment, medical scanners, and more.
The CA 8343 is intuitive to use and well-suited for energy efficiency analysis. It enables both the short-term analysis of rapid events and the monitoring of power quality parameters in accordance with the BDS EN 50160 standard and the criteria established by the EWRC (Energy and Water Regulatory Commission). Its compliance with the BDS EN IEC 61000-4-30 standard (Class A) allows it to be used for arbitration purposes in disputes between suppliers and consumers.
This device from the Qualistar series is suitable for all types of installations; it automatically detects the type of connected current sensors and ensures high measurement accuracy. Its capabilities—including the recording and visualization of inrush currents and fast transients, harmonic analysis (up to the 63rd order), analysis of unbalance and leakage currents, as well as the calculation of various parameters—provide the user with a powerful professional tool. The unit offers extensive connectivity options, including remote monitoring and the receipt of notifications regarding specific events or instances where pre-set threshold values are exceeded.
