The PWS 3.3 is a combination of a three-phase Portable Working Standard of class 0.05% or 0.1% and an IEC 61000-4-30 Class A compatible Power Quality Analyzer with 3 voltage and 4 current channels.

The Working Standard is used to test single and three phase meters, instrument transformers and installations on site. The Power Quality Analyzer is used to resolve disputes at contractual applications, for statistical surveys, including EN 50160 reporting, and for online troubleshooting of different kind of power quality problems.

The unit can be used with various types of clamp-on CTs and current sensors. Therefore it is possible to easily and accurately test both CT and direct connected meters.

The unit can be powered either from the measuring circuit or from an auxiliary single-phase supply. Power Quality Analysis is battery buffered during 15 min in case of an outage.
