1. INTRODUCTION
C.A 8332B and C.A 8334B are three phase power quality analysers which are compact and shock-resistant. Their ergonomic
design and the simplicity of their user interface make their use pleasant and intuitive.
They not only enable the user to obtain an instant image of a network’s principal characteristics but also to monitor their variation
over a period of time.Their multi-task measurement system simultaneously handles all the measurement functions of the various
magnitudes, detection, continuous recording: and their display without any constraints.
They are intended for the technicians and engineers of the test and maintenance teams working in industry and the administration,
for measurements, enabling them to carry out checks and diagnostic work on single phase, two phase or three phase low voltage
networks.
The principal measurements made are:
-Measurement of AC rms voltages up to 480V (phase-to-neutral) or 960V (phase-to-phase) for two-wire, three-wire or four-wire networks.
-Measurement of alternating RMS currents up to 6500A rms.
-Measurement of the frequency of 50Hz, 60Hz (10Hz to 70Hz) networks.
-Calculation of neutral current by vector summing of phase current for star configurations.
-Calculation of peak factors for currents and voltages.
-Calculation of the K factor for currents (transformers).
-Calculation of short-term flicker for voltages.
-Calculation of the phase unbalance for voltage and current (three-phase networks only).
-Measurement of harmonic angles and rates (with respect to fundamental value) for voltage, current or power (C.A 8334B only),
up to level 50. Calculation of overall harmonic distortion factors.
-Measurement of active, reactive and apparent power per phase and their aggregate.
Calculation of the power, shift and tangent factor .
Total amount of energy generated and received from a moment chosen by the operator.
-Monitoring of the average value of any parameter, calculated over a period running from 1 sec to 2 hours.Storage of values
over an unlimited period in the instrument memory.
-Recording, time stamping and characterisation of disturbance: Swells, dips and interruptions, overrun of power and harmonic
thresholds...
-Detection of transients and recording of the associated waveforms (C.A 8334B only).

Single phase or two-phase ,the neutral current is not measured or calculated.
3-wire, three phase :
1. Three phase, triangle network: only power totals are representative of the actual situation
2. Three-phase star network: the neutral current is not calculated. It is necessary to connect neutral to obtain representative
power levels per phase.
4-wire three-phase : the neutral current is calculated and its value and waveform are displayed.
V1 must be connected in any type of connection since the display is synchronised from V1 and the network frequency
measured by V1.
