The CA 8345 from Chauvin Arnoux is a power and power quality analyzer of the Qualistar series, certified according to IEC 61000-4-30 Edition 4 in Class A. The device is used for diagnosing and monitoring voltage quality in industrial, commercial, and public installations. It enables precise measurement of network parameters such as voltage, current, power, energy, harmonics, interharmonics, flicker, and transient disturbances. Measurements are performed via isolated inputs for voltage and current, with voltage measurement supporting up to 1000 VAC/DC. The device class CAT IV 1000 V ensures safe measurement in high-voltage environments.

Voltage quality analysis and compliance with standards
The CA 8345 meets the requirements of standard IEC 61000-4-30 Ed.4 in Class A, which means full compliance for measuring voltage quality parameters in AC networks. It is suitable for monitoring according to EN 50160, with evaluation performed via the PAT3 software. Harmonic measurements are carried out according to IEC 61000-4-7, covering harmonic mode up to order 127 and interharmonic mode up to order 126. Flicker measurements are performed according to IEC 61000-4-15 to analyze short- and long-term light fluctuations.

Operation and display
The device features a 7-inch color touch LCD screen with a resolution of 800 x 480 pixels (WVGA), enabling intuitive operation. The user interface includes multilingual online help and a screen keyboard that activates automatically during input. The display supports trend and change diagrams, making signal parameter developments over time visible. Real-time measurement can be enabled to continuously display current values.

Data processing and storage
The CA 8345 stores measurement data on an externally accessible SD card, with no limit on storage size. Recording includes over 900 parameters, including trend data, harmonic phase recordings, and alarms. The alarm function supports up to 40 alarm types with a maximum of 20,000 alarm events. Inrush capture records up to 100 inrush currents, with TrueInrush capture including history for detecting high inrush currents. Transients can be captured with a resolution of 2.5 µs, and surge waves up to 12 kV over 500 ns are measured at a sampling rate of 2 Msps.

Communication and networking
The device supports various communication methods: USB, Ethernet (RJ45), Wi-Fi (directly as WAP or via server), and an integrated web server. Data can be transferred via USB stick, SD card, or network. In IRD server mode, measurement data can be accessed from anywhere in the world without compromising the security of the internet network. Data processing is performed using the PAT3 software, available on the manufacturer’s support website.

Technical equipment and operation
The CA 8345 operates with a Li-Ion battery cartridge, enabling up to 8 hours of autonomy. The operating temperature range is from +0 °C to +40 °C. The device is designed for environmental conditions according to IEC 61557-12 and IEC 62586. The protection class IP54 protects against dust and splashing water, making it suitable for indoor use. Dimensions are 200 x 285 x 55 mm, and weight is 1.9 kg. Sampling is performed at 400 ksps for voltage and 200 ksps for current. Additional operating modes include power mode, energy mode, and unbalance mode (composite).

Accessories and expansion options
To extend the device’s application, various current sensors are available, including clamps such as MN93A, C193, J93, PAC93, MN93, MINI94 (AC), E94, as well as Ampflex models A193-800mm and A193-450mm. Adapter housings such as 5A (F) or Essailec adapters, and power/charger units PA40W-2 or PA32ER (1000 V STD) are available. Additional accessories include a carrying strap, a cable reel (Reeling Box), a magnetic holder with hook, an SD card, and a USB key connector (Type A). The DataView software supports data analysis.

Operational benefits
The CA 8345 enables precise analysis of energy efficiency and power quality. Immediate display of key network parameters helps identify disturbance sources and plan maintenance activities. Networking capability and remote data transmission support continuous monitoring and centralized evaluation. High measurement accuracy and a wide range of calculation functions make the device a reliable tool for testing and maintenance services.

Applications
The device is particularly suitable for maintenance and testing of power distribution networks in industrial, commercial, and public facilities. It is used for determining energy balance, diagnosing voltage quality disturbances, and optimizing energy efficiency. Analysis of harmonics, flicker, and transient events helps avoid disturbances in electronic loads and extend the service life of system components.

Warranty
The CA 8345 is delivered with a 3-year warranty.
