What term describes loss in a power system that is primarily caused by human error?

The term that accurately describes loss in a power system primarily caused by human error is "Non-Technical Loss." This type of loss typically refers to a range of inefficiencies not related to the physical aspects of power delivery, such as electrical resistance or equipment failure, but rather to factors that can include human mistakes in operation, management inefficiencies, theft, or poor accounting practices.

Non-Technical Losses emphasize the impact of human decision-making and operational flaws in managing a power system, distinguishing it from technical losses which are inherent to the physics of electricity distribution and transmission. Understanding this distinction is crucial for addressing issues in utility management and improving overall system efficiency.

Other terms like "Technical Loss" focus specifically on losses that are unavoidable due to the physical characteristics of power systems, such as line losses. "Operational Loss" might suggest inefficiencies in processes but does not inherently specify human error as the cause. "Human Error Loss" is not a formal term commonly recognized in the field, making "Non-Technical Loss" the most suitable choice.
