nominell aktiv ström

Explanation:
Jag skulle tro att man menar den aktiva strömmen av grundtonen. Märkströmmen anges i effektivvärde (rms). Den aktiva strömmen ger upphov till en aktiv effekt, den reaktiva strömmen (fasförskjuten 90 grader) ger en reaktiv effekt. Den aktiva och den reaktiva strömmen sammanlagrade ger en skenbar effekt.
