Power transformers are important and one of the costliest equipment used in the transmission and distribution**of the electric energy. Despite great progresses in their design in recent years, the Achilles heel still remains the**insulation system. When power transformers fail, the fault can be traced usually to defective insulation.**Unexpected failures cause major disturbances to operating systems, resulting in unscheduled outages and**power delivery problems. Extreme reliability is demanded of electric power distribution as when failures occur**they inevitably lead to high repair costs, long downtime and possible personnel safety risks. By accurately**monitoring the condition of the insulation (moisture ingress, temperature, vibration, etc.) many types of faults**can be discovered before they become serious failures and outages.**Some of the research and development accomplishments by QPS during the past years have resulted in the**development of a Phase Shifted Gratings recoated sensor with multilayers of polyimide films. This fiber optic**sensor is designed to help plant owners monitor moisture, vibration and temperature inside oil filled**transformers. The proposed research aims at analysing field test data records and accurately calibrating the**sensor. The knowledge and technology that will develop from the proposed research are of great importance to**both Canadian manufacturing and power utility industries. The sensor has high potential for on-line monitoring**of transformers. Using the improved sensor will provide solutions to transformers integrity in smart grids,**assuring the system reliability.

电力变压器很重要，也是电能传输和分配**中使用的最昂贵的设备之一。尽管近年来其设计取得了巨大进步，但其致命弱点仍然是绝缘系统。当电力变压器发生故障时，故障通常可以追溯到绝缘缺陷。**意外故障会对操作系统造成重大干扰，从而导致计划外停电和**电力传输问题。配电需要极高的可靠性，因为当发生故障时**它们不可避免地会导致高昂的维修成本、长时间的停机以及可能的人员安全风险。通过准确**监测绝缘状况（湿气进入、温度、振动等），可以在多种类型的故障发展为严重故障和断电之前发现它们。**QPS 在过去几年中取得的一些研发成果导致**开发出具有多层聚酰亚胺薄膜的相移光栅重涂传感器。该光纤**传感器旨在帮助工厂所有者监控充油**变压器内的湿度、振动和温度。拟议的研究旨在分析现场测试数据记录并准确校准**传感器。拟议研究中开发的知识和技术对于加拿大制造业和电力行业都非常重要。该传感器在变压器在线监测**方面具有很高的潜力。使用改进的传感器将为智能电网中变压器的完整性提供解决方案，**确保系统的可靠性。
