Overhead lines, composed of conductors, insulators and towers are widely used at both the transmission and distribution level. Insulators provide electrical insulation between the tower and the conductors and provide mechanical support to the conductors. They are either polymer or ceramic which has been used for over 100 years. Detecting defects in ceramic insulators in smart, safe and cost effective scheme is becoming a crucial requirement. Defects range from minor cracks to punctured and broken discs leading to visible physical damage over the insulator structure, an increase in temperature, and excessive concentration of electric field.** The main objective of this project is to develop a smart unmanned aerial vehicle (UAV) to diagnose and detect physical damage in ceramic insulators. They can be examined by visual inspection with either a specialized camera or other interface. Any increase in temperature can be recorded using devices that are capable of measuring the infra-red (IR) radiation, such as an IR camera. The concentration of electric field can be identified using acoustic sensors or an ultra-violet (UV) camera. A quad-copter will be used to fly alongside the hydro towers to detect and localize damaged insulators. Ceramic insulator images will be collected and a detection scheme will be developed based on deep learning. This project will result in a prototype that is capable of diagnosing physical damage in ceramic insulators. This is the first step towards development of comprehensive autonomous drone inspection for outdoor ceramic power line insulators.** This project is in conjunction with METSCO, a company which brings energy solutions to the Canadian Energy Sector. The power grid forms the virtual backbone of our technological society, allowing us to power our lives and our devices. The aging insulator infrastructure causes a growing need to identify potential insulator faults before cost-destructive electrical blackouts occur due to insulator failure. Developing an efficient and cost effective inspection system is critical. The benefit to Canada of maintaining our smart grid system is abundantly clear as it impacts the day-to-day lives of all Canadians.**

架空线路由导线、绝缘子和杆塔组成，广泛应用于输变电和配电网。绝缘体在铁塔和导线之间提供电气绝缘，并为导线提供机械支撑。它们要么是聚合物，要么是已经使用了100多年的陶瓷。在智能、安全、经济的方案中检测陶瓷绝缘子的缺陷成为一项至关重要的要求。缺陷的范围从微小的裂纹到被刺破的圆盘，导致绝缘子结构上可见的物理损伤，温度升高，以及电场过度集中。**本项目的主要目标是开发一种智能无人机(UAV)来诊断和检测陶瓷绝缘子的物理损伤。它们可以用专门的摄像机或其他界面进行目测检查。温度的任何升高都可以使用能够测量红外线(IR)辐射的设备(如红外相机)来记录。电场的浓度可以使用声学传感器或紫外线(UV)相机来识别。一架四翼直升机将被用于沿水力塔飞行，以检测和定位损坏的绝缘子。将收集陶瓷绝缘子图像，并开发基于深度学习的检测方案。该项目将产生一种能够诊断陶瓷绝缘子物理损坏的原型。这是开发户外陶瓷电力线路绝缘子全面自主无人机检测的第一步。**该项目与为加拿大能源行业提供能源解决方案的METSCO公司合作。电网构成了我们技术社会的虚拟支柱，使我们能够为我们的生活和设备供电。老化的绝缘子基础设施导致在绝缘子故障导致成本破坏性的停电发生之前识别潜在的绝缘子故障的需求日益增长。开发一种高效率和高成本效益的检查系统至关重要。维护我们的智能电网系统对加拿大的好处是非常明显的，因为它影响到所有加拿大人的日常生活。
