Being able to monitor the condition of bushings used in high voltage apparatus is important for long-term**power system reliability. Over long periods, bushing insulation material can degrade due to surface**contamination or defects that develop due to stresses from exposure to high field strengths. Insulator**breakdown can lead to catastrophic failure, power outage, and potentially hazardous conditions. Power HV Inc.**manufactures high voltage bushings and has developed a sensor platform for monitoring bushing operating**condition. Power HV and Dr. G. Bridges at the University of Manitoba will initiate a partnership to develop a**transient earth voltage sensor for measuring partial discharge fields due to bushing insulator faults. The sensor**will be connected to the sensor platform which will sample and wirelessly transmit the partial discharge signals**to a remote server for processing. The sensor platform will be located on the high voltage apparatus, but in**order to provide long-term remote operation without hazardous human intervention, a batteryless source of**power is required. To address this the research team will develop an inductive coil-based energy harvesting**scheme which directly harvests power from the magnetic field generated by the bushing current. The remote**monitoring capability will greatly improve the safety and long-term reliability of power apparatus and provide**Power HV with a unique capability that will enhance the marketability of their products.

能够监测高压设备中使用的套管的状态对于电力系统的长期可靠性是重要的。在长时间内，套管绝缘材料会由于表面污染或由于暴露于高场强的应力而产生的缺陷而退化。绝缘子 ** 击穿可导致灾难性故障、断电和潜在危险情况。Power HV Inc.制造高压套管，并开发了一种监测套管运行状态的传感器平台。Power HV和Dr. G.马尼托巴大学的桥梁将发起一个合作伙伴关系，开发一个 ** 瞬态接地电压传感器，用于测量局部放电场由于套管绝缘子故障。传感器 ** 将连接到传感器平台，传感器平台将采样并无线传输局部放电信号 ** 到远程服务器进行处理。传感器平台将位于高压设备上，但为了提供长期远程操作而无需危险的人为干预，需要无电池的电源。为了解决这个问题，研究小组将开发一种基于感应线圈的能量收集方案，该方案直接从套管电流产生的磁场中收集电力。远程监控能力将大大提高电力设备的安全性和长期可靠性，并为 **Power HV提供独特的能力，将提高其产品的市场竞争力。
