Qualistar CA8333 Power Quality Analyser


Designed for test and maintenance departments working in industrial or administrative buildings, the Qualistar+ C.A 8333 can be used to obtain a snapshot of the main features characterising the quality of the electrical network.. This analyser’s functions make it the ideal instrument for preventive or corrective maintenance. It can also be used to perform a complete energy survey of an installation.

For sizing installations or troubleshooting switching faults, the C.A 8333 is equipped with a transient mode which allows users to measure the inrush current over 4 periods.

Easy to handle and particularly compact, this instrument also offers a large number of calculated values and several processing functions. The C.A 8333 is equipped with 3 voltage measurement channels and 3 current measurement channels. The C.A 8333 captures and records all the parameters, transients, alarms and waveforms simultaneously.

When current sensors are connected to the C.A 8333, it recognises them automatically. It also offers the possibility of mixing different types of current sensors and configuration of the ratios allows direct reading of the measurements.

Specially designed for work in the field

The multiple functions of the Qualistar+ C.A 8333 make it a versatile instrument. It is suitable for applications up to 1,000 V in CAT III and 600 V in CAT IV.


The measurements obtained with the Qualistar models can be processed using two software tools: PAT delivered as standard and Dataview®, available as an option. They allow configuration, transfers, processing and analysis. In addition, Dataview® offers the possibility of generating reports according to the voltage quality standards.
