sähköhäviöitä
Sähköhäviöitä are energy losses that occur during the transmission and distribution of electrical power. These losses are an inherent part of any electrical system and result from various physical phenomena. The primary cause of sähköhäviöitä is the resistance of the conductors, typically made of copper or aluminum. As electric current flows through these conductors, some electrical energy is converted into heat due to this resistance, a phenomenon known as Joule heating. This resistive loss is proportional to the square of the current and the resistance of the conductor.
Another significant source of sähköhäviöitä is magnetic losses, which occur in the iron cores of transformers
Furthermore, sähköhäviöitä can arise from corona discharge, an electrical breakdown of the air surrounding high-voltage conductors.
