The CA 8345 from Chauvin Arnoux is a power and power quality analyzer of the Qualistar series, specifically designed for diagnosing and monitoring electrical voltage quality in industrial and commercial facilities. The device meets the requirements of standard IEC 61000-4-30 Edition 4, Class A, and is therefore suitable for precise measurements of voltage, current, power, energy, harmonics, and disturbances. It features a 7-inch color touch LCD screen with a resolution of 800 x 480 pixels (WVGA), enabling intuitive operation and simultaneously displaying multilingual online help. Measurements are captured via isolated inputs, with voltage measurement supporting up to 1000 VAC/DC. The safety class CAT IV 1000 V ensures safe operation at high voltages.

Applications

The CA 8345 is intended for testing and maintenance services in industrial, commercial, and public facilities. It is used to determine the energy balance of a site, with measurement data analyzed to assess actual power consumption and evaluate billing amounts. The results enable identification of inefficiencies and planning of measures such as re-dimensioning transformers, installing filter systems, or replacing faulty equipment. The increasing prevalence of electronic loads leads to higher harmonic distortions, which can be detected and analyzed with the CA 8345 to prevent disturbances or failures in connected devices.

Functions and Equipment in Detail

The device offers a variety of measurement modes, including real-time mode, power mode, energy mode, and unbalance mode. It captures harmonics up to order 127 and interharmonics up to order 126, with measurements performed according to IEC 61000-4-7. Inrush current capture allows documentation of high inrush currents, with up to 100 events stored. Transients with a duration of 2.5 µs and surge waves up to 12 kV over 500 ns are captured at a sampling rate of 2 Msps. Trend recording includes more than 900 parameters, with harmonic phase recording also supported. The alarm mode offers 40 different alarm types with a maximum of 20,000 alarms. The device detects carrier signals in the network and allows setting alarms that can be sent to the user via email.

Technology Explained Simply

Sampling is performed at 400 ksps for voltage and 200 ksps for current, enabling accurate capture of rapid signal changes. The Li-Ion battery cartridge provides autonomy of up to 8 hours, allowing the device to be used independently of mains power supply. Data is stored on an externally accessible SD card, which can be replaced at any time. Storage is unlimited, as capacity is determined by the SD card used. Communication is via USB, Ethernet (RJ45), and Wi-Fi, with the device also functioning as an IRD server to retrieve measurement data from anywhere in the world. An integrated web server enables access to data via network connections.

Compatibility and Accessories

The CA 8345 is compatible with a wide range of current sensors available under the Qualistar accessory series. These include various clamp types such as MN93A, C193, J93, PAC93, MN93, MINI94 (AC), E94, as well as Ampflex models like A193-800mm and A193-450mm. Additionally, adapter housings such as 5A (F) and Essailec adapters are available. Software DataView, as well as power/charger units PA40W-2 and PA32ER, are available as accessories. An SD card, a magnetic holder with hook, and a Reeling Box – cable winder with magnet – further enhance usability. Measurement data can be analyzed using the PAT3 software, which can be downloaded from the manufacturer’s support website.

Mounting and Installation

The device is compact and designed for mobile use. Installation is performed by connecting current sensors to the isolated inputs. Sensors are selected according to application and attached to the respective conductors. Communication is via USB, Ethernet, or Wi-Fi, with connections established via USB stick, SD card, or network connection. Operation is via the touchscreen, with the on-screen keyboard automatically displayed whenever input is required.

Operational Advantages

The CA 8345 offers high measurement accuracy and comprehensive data analysis, which are crucial for optimizing energy efficiency and ensuring power quality. The integrated trend recording and the ability to configure alarms with email notifications enable proactive network monitoring. Networking capabilities via USB, Ethernet, and Wi-Fi, along with the integrated web server, allow flexible data transfer and analysis. The 3-year warranty underscores the device’s reliability. The IP54 protection class safeguards against dust and splashing water, enabling use in industrial environments. The operating temperature ranges from +0 °C to +40 °C, allowing use in a wide range of environments. Dimensions are 200 x 285 x 55 mm, and the device weighs 1.9 kg.
