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 me-ters, instrument transformers and installations on site.
The Power Quality Analyzer is used to resolve disputes at contrac-tual applications, for statistical surveys, including EN 50160 report-ing, and for online troubleshooting of different kind of power quality problems.
The unit can be used with various types of clamp-on CTs and cur-rent and voltage sensors. Therefore, it is possible to easily and ac-curately test both CT/PT 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 min. 15 minutes in case of an outage.

Meter constant:
Active, Reactive, Apparent [imp/Wh(varh,VAh)]
C = 36’000’000 / (In * Un)
The meter constant depends on the highest selected internal ranges In, Un.
Example: Un = 300V, In = 12 A)
C = 10’000 [imp/Wh(varh,VAh)]
Output frequency:
C’ = C / 3’600 [imp/Ws(vars, VAs)] fo = C’ *PS(QS, SS)
fmax = 36’000’000 / (12 * 300 * 3’600) *
3 * 12 * 300 = 30’000 [imp/s]
