Power distribution voltages and insulation are areas of critical importance to the study of SSP systems. Due to the importance of the mass and cost of the SSP system, most designs for the SSP operate at high voltages in order to reduce transmission losses and mass. Some design concepts even use no insulation. Use of these high voltages will present challenges of electrical breakdown and performance of insulators, insulation, and switchgear. As a result, there is a strong research motivation for technology geared towards enhancement of PMAD systems exposed to electrical breakdown and corona type faults. In harsh environments (aerospace), economic and effective fault management (maintenance and monitoring of electric power systems) is needed to ensure high performance. In the effective fault management of the aerospace environment, the maintenance cost of aging distribution cables is a major consideration. The installation and maintenance of the equipment on board the SSP is also of high significance. These operations can be significantly improved by more accurate predictions of insulating aging, as well as detection and location of faults within the components of the power system. This project will focus on the design of an integrated system using state-of-the-art technology for continuous and periodic monitoring of a space power system with emphasis on the detection and diagnosis of corona and soft faults. This scheme involves the cost effective, efficient monitoring and control for an enhanced space solar power network. A network of sensors will monitor the network, report information for the detection of faults, and provide health-status information of electrical insulation and other components in the system. The Center for Energy Systems and Control (CESaC), Howard University is one of the research centers in the US that has demonstrated capabilities in the following combination of fields: Power system analysis in the terrestrial, non-terrestrial, naval systems, and spacecraft energy power systems; Application of optimization techniques to improve the solution of different problems, and applications of intelligent systems to the solution of complex problems. This combination is necessary for completion of the complex interdisciplinary tasks that will be faced in this project. The project will create an opportunity for students from differing branches of electrical engineering - material sciences, communications, power systems and controls - to become aware of modern problems in the power industry and contribute to the technical progress in this field.

配电电压和绝缘是 SSP 系统研究中至关重要的领域。由于 SSP 系统的质量和成本的重要性，大多数 SSP 设计都在高电压下运行，以减少传输损耗和质量。有些设计理念甚至不使用绝缘材料。使用这些高电压将带来电击穿以及绝缘体、绝缘体和开关设备性能的挑战。因此，对于旨在增强暴露于电气击穿和电晕类型故障的 PMAD 系统的技术有很强的研究动机。 在恶劣环境（航空航天）中，需要经济有效的故障管理（电力系统的维护和监控）以确保高性能。在航空航天环境的有效故障管理中，老化配电电缆的维护成本是一个主要考虑因素。 SSP上设备的安装和维护也具有重要意义。 通过更准确地预测绝缘老化以及检测和定位电力系统组件内的故障，可以显着改善这些操作。 该项目将重点设计一个集成系统，采用最先进的技术对空间电力系统进行连续和定期监测，重点是电晕和软故障的检测和诊断。该方案涉及对增强型空间太阳能发电网络进行成本效益高、高效的监测和控制。传感器网络将监视网络，报告故障检测信息，并提供系统中电气绝缘和其他组件的健康状态信息。 霍华德大学能源系统与控制中心 (CESaC) 是美国研究中心之一，在以下领域组合中展示了能力： 陆地、非陆地、海军系统和航天器能源中的电力系统分析电力系统； 应用优化技术改进不同问题的解决方案，应用智能系统解决复杂问题。这种结合对于完成该项目将面临的复杂的跨学科任务是必要的。该项目将为来自电气工程不同分支（材料科学、通信、电力系统和控制）的学生创造一个机会，让他们了解电力行业的现代问题，并为该领域的技术进步做出贡献。
