The Qualistar+ C.A 8336 from Chauvin Arnoux is a voltage quality analyser with 4 voltage and 4 current measurement channels, specifically designed for maintenance and testing services in industrial and commercial installations. The device simultaneously captures all relevant electrical parameters, including powers, energies, harmonics, transients, flicker, and alarms, providing comprehensive analysis of power quality. It is suitable for use in installations of category CAT III up to 1000 V and CAT IV up to 600 V, making it applicable for various fields in electrical engineering and energy supply.

Applications

The C.A 8336 is particularly used in the maintenance, repair, and sizing of electrical installations. It enables the creation of a complete energy balance and is used for detecting switching errors and analysing inrush currents (Inrush mode). The TrueInrush function supports precise evaluation of switching events, which is important for diagnosing device faults or planning installations. The versatility of the device also makes it suitable for testing meters, protection relays, or secondary circuits of transformers, especially when the power supply must not be interrupted.

Functions and Equipment in Detail

The device features a colour TFT display with a resolution of 320 x 240 pixels (¼ VGA) and a diagonal of 148 mm, clearly displaying all measurement values. The user interface is optimised for on-site use, with direct access to key functions such as harmonic analysis, flicker measurement, and settings. Voltage and current inputs are colour-coded to enable quick and error-free wiring. Automatic detection of connected current transformers (e.g. C193, AmpFLEX®, PAC93, E3N/E27, J93) and setting of transformation ratios allow direct reading of measurement values without manual calibration.

Technology Explained Simply

The C.A 8336 measures voltages in the range of 2 V to 1,000 V (TRMS AC+DC) and current values depending on the clamp used, from 50 mA to 10,000 Aac (AmpFLEX®) or up to 5,000 Adc (J93). Frequency measurement is performed in the range of 40 Hz to 69 Hz. Power measurement includes active power (W), apparent power (VA), reactive power (var), power factor (PF), dispersion factor (DPF), cos φ, tan φ, as well as energy forms Wh, varh, and VAh. Harmonic analysis captures harmonics up to the 50th order with phase position, with the expert mode offering extended analysis options. Transient capture is limited to up to 210 events, and flicker is measured according to parameters Pst and Plt. The Inrush mode captures inrush currents over a duration of more than 10 minutes with waveform display.

Compatibility and Accessories

The device is compatible with a wide range of current transformers, including clamps such as C193, PAC93, E3N/E27, J93, MN93A, MN93, E94, as well as AmpFLEX® models. The use of adapters such as USB/RS232, cigarette lighter adapter, or power adapter PA31ER enables flexible power supply. Software PAT2 is available as standard, while software DataView® is offered optionally for data processing, analysis, and generating standard-compliant test reports (EN50160). Additional accessories include a set of coloured marking parts, a screen protector, a 5A (F) adapter housing, and a Reeling Box with magnet for storing test leads.

Mounting and Installation

The C.A 8336 is designed as a compact, portable device intended for direct on-site use. Test leads are connected to the colour-coded inputs, with automatic detection of current transformers simplifying operation. Power supply is either via a rechargeable NiMH battery (9.6 V) or mains power. The autonomy is up to 10 hours in operation, enabling extended measurement duration without external power supply.

Advantages in Operation

The device offers high measurement accuracy and simultaneous capture of all parameters, increasing efficiency in diagnosis and maintenance. The integrated memory function allows recording of up to 50 screen and curve captures. The alarm function captures up to 10,000 events from 40 different alarm types, with alarms triggered as early as half a cycle. Vector representation provides visual analysis of phase relationships, and support for more than 27 languages facilitates operation in international environments. Protection class IP53 and IK08 ensure reliable operation under harsh conditions, and compliance with IEC 61000-4-30 and reporting according to EN50160 guarantee conformity with international standards.

Accessories and Extensions

Available accessories include adapters for USB/RS232, cigarette lighter adapter, 5A (F) adapter housing, set of coloured marking parts, screen protector, power/charger PA30W, software DataView, BNC adapter for E3N/E27, clamps such as MN93A, C193, J93, PAC93, E27 CVH, E94, Ampflex A193-450 mm, clamp MN93, Essailec adapter housing, set of 2 magnetic test probes (4A, 1000V CAT III / 600V CAT IV), Reeling Box with magnet, power adapter PA31ER, and ESSAILEC test lead. These components extend the functionality and applicability of the device in various application scenarios.

Standards and Norms

The device complies with IEC 61000-4-30 and generates reports according to EN50160. Electrical safety is certified according to IEC 61010 for CAT III 1000 V and CAT IV 600 V. Protection class IP53 protects against dust and splashing water, IK08 protects against mechanical impacts. The devices are available in more than 27 languages, facilitating international use.

Application Scenarios

The C.A 8336 is used in industrial electrical engineering, by energy supply companies, in building technology, and by testing service providers. It is used for diagnosing network disturbances, monitoring energy quality, maintaining installations, and generating test reports. The combination of versatile measurement functions, high accuracy, and mobile use makes it a central tool for professionals in the field of electrical and energy technology.
