Chauvin Arnoux P01160620 CA 8220 power analyzer (without current transformer) content_copy

The C.A 8220 is a single-phase power analyser from Chauvin Arnoux, designed for the analysis of electrical networks and the maintenance of electric motors. The device is designed for industrial use, both in the field and in the laboratory, and is suitable for single-phase networks as well as symmetrical three-phase networks. It features a robust, shock-resistant housing and a clear liquid crystal segment display that immediately shows the main power parameters such as kW, kVAR and kVA. Additionally, inrush currents (starting currents), energies and harmonics up to the 50th order are measured, enabling comprehensive diagnosis of electrical systems.

Applications

The C.A 8220 is particularly used in industrial electrical engineering, where precise analysis of power supplies and motors is required. It is suitable for the maintenance and diagnosis of electric motors, especially within the context of preventive maintenance. The measurement of harmonics up to the 50th order supports the assessment of power quality and helps identify disturbances in the network. Compatibility with various current transformers extends the application range from a few milliamperes up to 6.5 kA.

Functions and Equipment in Detail

In addition to basic power parameters, the device offers additional functions such as speed measurement and temperature measurement via integrated temperature sensors. These functions are particularly relevant for monitoring electric motors, as they provide direct insight into the operating condition of the drive. Speed measurement enables assessment of mechanical performance, while temperature measurement provides early warning of overheating or inefficient operating conditions.

Technology Explained Simply

Measurement is performed via an optical USB interface, ensuring secure and interference-free data transmission. The included software Power Analyzer Transfer (PAT) enables evaluation of the measurement results on a PC. The software is available for free download and supports analysis of the recorded data, including representation of harmonics and energies. The segment display ensures clear and immediately understandable presentation of values, even under difficult environmental conditions.

Compatibility and Accessories

The C.A 8220 is compatible with a wide range of current transformers, making it suitable for various applications across different current ranges. The exact selection of the current transformer depends on the current to be measured. The use of appropriate current transformers is essential for measuring currents from a few milliamperes up to 6.5 kA. The PAT software supports data evaluation, which is transmitted via the optical USB interface.

Mounting and Installation

Installation is performed by direct connection to the network to be measured. Current transformers must be selected according to the current to be measured and installed on the conductor. The device display shows the measured values directly. Data transmission is carried out via the included optical USB cable, which is connected to a PC.

Advantages in Operation

The C.A 8220 is characterised by simple and intuitive operation. The robust housing allows use under harsh conditions, both in the laboratory and in the field. The combination of power analysis, speed and temperature measurement provides comprehensive diagnostic functionality for electrical drives. The fast and precise evaluation of data via the PAT software supports decision-making for maintenance and repair activities. The optical USB interface ensures reliable data transmission without electromagnetic interference.

The delivery includes the C.A 8220 power analyser, the Power Analyzer Transfer (PAT) software, the optical USB cable and the operating instructions.
