The Qualistar+ C.A 8436 is a three-phase graphical power, energy, harmonic, and disturbance analyzer from Chauvin Arnoux, designed for use under demanding conditions. The device features 5 voltage inputs and 4 current inputs, enabling comprehensive measurement of all electrical parameters in a network. It is specifically designed for voltage quality analysis, rapid testing of power systems, and efficient evaluation of measurement values. Measurements are performed simultaneously for voltage, current, and power parameters, as well as network quality indicators, transients, alarms, and signal waveforms. The device functions meet the requirements of IEC 61000-4-30 Class B and EN50160 Ed02 standards.

Applications

The C.A 8436 is suitable for maintenance and testing services in industrial, commercial, and public facilities. It can be used in single-phase, two-phase, and three-phase systems with or without a neutral conductor, including installations using the two-wattmeter method or ARON circuit. The robust construction with IP67 protection rating makes the device dust-tight and waterproof, allowing operation outdoors, on construction sites, or in harsh environments. Measurements are performed in the categories 1.000 V CAT III and 600 V CAT IV, ensuring safe use in industrial networks.

Functions and Equipment in Detail

The device 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 A (depending on the current transformer). Frequency measurement is performed in the range of 40 Hz to 69 Hz. It calculates power values such as active power (P), reactive power (Q), apparent power (S), distorted power (D), power factor (PF), displacement factor (DPF), cos φ, and tan φ. Energy parameters such as Wh, varh (Qh, Nh, Dh), and VAh are recorded in total and per phase. The analysis includes harmonics up to the 50th order, THD values from rank 0 to 50 per phase, flicker (Pst and Plt), and voltage and current unbalance. The Inrush mode records inrush currents over a period of up to 10 minutes. Device functions also include recording up to 210 transients and configuring up to 40 alarms, with a total of 10,000 alarm events that can be stored.

Technology Explained Simply

The C.A 8436 features a TFT color display with a diagonal of 148 mm (320 x 240 pixels, ¼ VGA), which displays measurement values in real time. The display includes vector representations, phase diagrams, and waveforms. Operation is performed via a structured keypad with direct access to main functions such as harmonics, flicker, settings, and screen copy. The symbols of the keys are repeated on the screen, facilitating operation. Device functions include an expert mode that enables advanced analysis features. The storage function starts immediately after startup, ensuring immediate data recording. Up to 50 screen and curve captures can be saved.

Compatibility and Accessories

The analyzer is compatible with the entire Qualistar measurement accessory range. This includes current clamps such as C193 (1 A to 1.000 Aac), PAC93 (1 A to 1.300 Aac/dc), E3N/E27 (50 mA to 100 Aac/dc), J93 (50 A to 3.500 Aac / 50 A to 5.000 Adc), as well as AmpFLEX® clamps (30 A to 6.500 A AC). Additional accessories include adapters such as USB/RS232, BNC adapters for E3N/E27, clamps such as MN93A, MN93, E27 CVH, as well as magnetic measurement tips, crocodile clips, rubber plugs, and protective films. The DataView software enables configuration, evaluation, and export of measurement results to Excel.

Installation and Mounting

Installation is performed by directly connecting the measurement clamps to the current conductors and the voltage inputs to the voltage conductors. The connections are marked with color-coded rings to enable clear identification. Device functions support automatic detection of the used current transformers. The device can be operated with a rechargeable NiMH battery (9.6 V) or via mains power supply. The autonomy lasts up to 10 hours.

Operational Advantages

The C.A 8436 offers comprehensive diagnosis of electrical systems through simultaneous capture of all relevant parameters. The robust construction with IP67 protection rating ensures reliable operation under harsh conditions. The integrated software enables easy data transfer and analysis. Device functions support energy efficiency analysis and compliance with standards such as EN50160. The user interface is intuitively designed, making operation easy even for less experienced users. The storage function and alarm functions enable continuous monitoring and documentation of network parameters.

Protection Rating and Safety

The device complies with IEC 61010 and is approved for measurement categories 1.000 V CAT III and 600 V CAT IV. The IP67 protection rating means the device is dust-tight and protected against temporary water ingress, making it suitable for outdoor use and in damp environments. Electrical safety is ensured by compliance with the mentioned standards.

Communication and Software

Communication is performed via a USB interface. The included Power Analyser Transfer software enables device configuration, reading of measurement results, analysis, and export of data to Excel. The software supports real-time communication with a PC and report generation according to EN50160.

Languages and User-Friendliness

The device supports more than 27 languages, facilitating international use. The user interface is designed for intuitive operation, with key symbols repeated on the screen. The display is excellently readable and provides a clear representation of measurement values.

Dimensions and Weight

Dimensions are 270 x 250 x 180 mm, weight is 3.7 kg. The device is compact and can be safely transported and operated even in harsh environments. The stable construction with folding support enables secure placement during measurement.
