tehonhäviöitä
Tehonhäviöitä, or power losses, refer to the reduction in electrical power that occurs during the transmission, distribution, and utilization of electricity. These losses are an inherent part of any electrical system and arise from various physical phenomena.
The primary source of power loss in electrical conductors is Joule heating, also known as resistive loss.
In AC (alternating current) systems, additional losses occur due to factors like eddy currents and hysteresis
Power transformers, essential for stepping voltage up or down, also experience losses. Core losses, comprising eddy
In distribution systems, the length and resistance of power lines contribute significantly to overall power loss.
While complete elimination of power losses is impossible, engineers continuously work to minimize them through the
