Electrical losses across transmission and distribution networks represent one of the most critical engineering and economic challenges facing the global power sector. The dissipation of energy during transit from power generation facilities to end-users results in substantial financial losses, unnecessary depletion of natural energy resources, and elevated carbon emissions. These power losses are broadly categorized into two main types: Technical Losses, driven by the intrinsic physical properties of conductors and equipment, and Non-Technical Losses, caused by unauthorized consumption, administrative errors, and metering inaccuracies.The primary engineering challenges underlying technical losses center on conductor electrical resistance and Joule heating effects ($I^2R$), alongside severe voltage drops over long-distance transmission corridors, phase load imbalances, and low power factors induced by inductive loads. Furthermore, legacy transformers with poor energy efficiency contribute to continuous core and copper losses, exacerbated by harmonic distortions from non-linear power electronic loads. On the non-technical side, key operational bottlenecks include direct illegal grid connections, meter tampering, and the absence of real-time monitoring infrastructure to locate theft and leakage points precisely.To resolve these technical hurdles and minimize energy dissipation, researchers and engineers have deployed a suite of advanced technological and practical solutions. Foremost among these is stepping up transmission voltage levels and expanding High-Voltage Direct Current (HVDC) infrastructure to drastically diminish resistive losses across long distances, paired with reactive power compensation via shunt capacitors and FACTS devices to elevate power factor and reduce line current. Additionally, deploying high-efficiency amorphous core transformers and replacing conventional overhead lines with high-temperature low-sag (HTLS) or larger cross-sectional conductors significantly curtails technical losses. This framework is reinforced by Advanced Metering Infrastructure (AMI) and Smart Grid SCADA telemetry systems for automated theft detection, dynamic power flow optimization, and high-precision loss localization.Al-Mustaqbal University – The First Private University in Iraq
