The Qualistar+ C.A 8333 is a network analyser from the brand Chauvin Arnoux, specifically designed for maintenance and testing services in industrial and commercial installations. The device is used for comprehensive analysis of voltage, current, and power parameters in electrical networks and enables simultaneous capture of network quality parameters, transients, alarms, and signal waveforms. It is designed for on-site use and features a compact, robust design with a battery runtime of up to 13 hours. The measurement values are displayed on a colour TFT screen with a resolution of 320 x 240 pixels (¼ VGA, diagonal 148 mm), ensuring intuitive operation and immediate visualisation of the most important network quality parameters.

Applications

The C.A 8333 is suitable for diagnosing and maintaining electrical installations in industrial and commercial environments. It is used to create an energy balance for an installation, detect network disturbances, support the dimensioning of electrical systems, and identify switching faults. Functions such as the Inrush mode for capturing inrush currents over 4 network cycles, as well as harmonic and transient analysis, make the device particularly suitable for fault diagnosis and network quality assessment. Measurements are performed in accordance with standards IEC 61000-4-30 and EN50160, enabling the use for standard-compliant test reports.

Functions and Equipment in Detail

The device features 4 voltage inputs and 3 current inputs, colour-coded to allow easy assignment to phases. Automatic detection of connected current transformers simplifies operation. The measurement ranges include voltages from 2 V to 1,000 V (TRMS AC+DC) and currents from 5 mA to 10,000 Aac, depending on the current transformer used. Current transformers C193, AmpFLEX®/MiniFlex, PAC93, E3N/E27, and J93 allow flexible adaptation to different applications. Measurements are performed in the frequency range of 40 Hz to 69 Hz. Power parameters include active power (W), apparent power (VA), reactive power (var), power factor (PF), dispersion factor (DPF), cos φ, and tan φ. Energy values such as Wh, varh, and VAh are also recorded. Harmonic analysis is performed up to the 50th order with phase position, and THD (total harmonic distortion) is also determined. The expert mode offers extended functions for specialised applications.

Technology Explained Simply

The C.A 8333 measures all relevant electrical parameters of a network simultaneously, enabling comprehensive diagnosis. Simultaneous capture of transients (up to 50 events) and alarms (4,000 values for 10 alarm types) ensures that short-term disturbances and critical conditions are not overlooked. Peak value determination and vector representation (automatic) support visual analysis of network parameters. Screen and curve capture (12 captures) allow storage of measurement results for later evaluation. Power supply is via a rechargeable NiMH battery (9.6 V) or mains power. Electrical safety complies with IEC 61010 standard, with category CAT III 1,000 V and CAT IV 600 V, ensuring safe use in industrial environments. The protection rating IP53 protects against dust and splashing water, and IK08 protects against mechanical impacts.

Compatibility and Accessories

The device is compatible with a wide range of current transformers covering currents from 5 mA to 10,000 Aac. The ESSAILEC test lead enables testing of meters, built-in protection relays, or secondary circuits of voltage or current transformers without interrupting power supply. The Power Analyser Transfer software is included as standard and is used for configuration, data transfer, and analysis of measurement results. The Dataview® software is available as an option and enables the creation of standard-compliant test reports. The PA31ER power adapter can be used for power supply via a mains phase conductor (100 V to 1,000 V, AC/DC). The Reeling Box is used for orderly storage of test leads.

Mounting and Installation

The C.A 8333 is designed as a portable device and does not require fixed mounting. Test leads are connected to the colour-coded inputs, with automatic detection of current transformers simplifying operation. Current transformers are selected according to application and connected to the current inputs. Measurements are performed directly on the installation, with safety regulations according to IEC 61010 standard must be observed. Power supply is either via the internal battery or via the PA31ER power adapter.

Operational Advantages

The C.A 8333 offers high measurement accuracy and comprehensive functionality in a compact device. Simultaneous capture of all parameters reduces measurement time and increases diagnostic reliability. Intuitive operation through colour coding and automatic detection of current transformers reduces error susceptibility. The long battery runtime of up to 13 hours allows use throughout a full working day without interruption. Support for more than 27 languages increases user-friendliness in international operating environments. The ability to create standard-compliant test reports makes the device particularly suitable for professional testing and maintenance work. The integrated USB interface enables easy data transfer for further evaluation.

Scope of Delivery

The device is delivered with the Power Analyser Transfer software, a USB cable, colour-coded pins and rings for the inputs, an operating manual, a transport case, and the device itself. Optional accessories include the Dataview® software, the ESSAILEC test lead, and the PA31ER power adapter.
