 Abstract
The decision of installing a frequency static converter for pumps activating to transporting system of oil through the main pipelines is always justified by the electrical energy saving for the whole life of the equipment. But energy saving does not depend only on the frequency static converter or on the activating motor, but also on the transporting system characteristics, and a correct decision regarding the investment must avoid those calculation errors which may overestimate this saving.

 Rezumat
Decizia instalării unei convertizor static de frecvenţă pentru acţionarea pompelor din sistemul de transport al produselor petroliere prin conducte magistrale are īntotdeauna ca justificare, economia de energie electrică realizată pe durata de viaţă a echipamentului. Economia de energie nu este īnsă dependentă numai de convertizorul static de frecvenţă sau de motorul de acţionare, ci de caracteristicile sistemului de transport, iar o decizie corectă privind investiţia trebuie să evite acele erori de calcul care pot supraestima această economie.
