What is typically the cause of 'Technical Loss' in a power system?

Technical loss in a power system primarily refers to the unavoidable loss of energy that occurs during the transmission and distribution of electricity. These losses are mainly related to the physical properties of electrical components, such as resistance in conductors, which results in heat production as electrical energy passes through them.

Conversion losses through power lines are indeed a significant contributor to technical losses. As electricity travels along transmission and distribution lines, some amount of the energy is dissipated due to the inherent electrical resistance of the material used in the lines. This energy loss is essentially unavoidable and is classified as a technical loss because it is a direct result of the physical characteristics of the power system rather than external factors.

While equipment failure, human error, and scheduling discrepancies can lead to operational inefficiencies or outages, they typically fall under categories such as non-technical losses or operational issues rather than direct technical losses. These alternatives highlight occasions where power might not reach the consumer effectively, but they do not reflect the fundamental energy losses that occur during the standard operation of transmission lines due to physical properties. Thus, the correct identification of conversion losses through power lines as the primary source of technical loss aligns closely with the principles of electrical engineering and power system operations.
