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.

电力变压器是用于电能传输和分配的重要设备，也是最昂贵的设备之一。尽管近年来在设计上取得了很大的进步，但阿喀琉斯的脚跟仍然是**绝缘系统。当电力变压器发生故障时，故障通常可以追溯到有缺陷的绝缘。**意外故障会对操作系统造成重大干扰，导致计划外停电和**电力输送问题。配电要求极高的可靠性，因为当发生故障时，不可避免地会导致高昂的维修成本、长时间的停机时间和可能的人员安全风险。通过准确**监控绝缘状况(入水、温度、振动等)许多类型的故障**可以在它们成为严重故障和停机之前被发现。**QPS在过去几年中取得的一些研究和开发成果**导致了**采用多层聚酰亚胺薄膜的相移光栅重涂传感器的开发。这种光纤**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。拟议中的研究将发展出的知识和技术对**加拿大制造业和电力公用事业行业都非常重要。该传感器对变压器的在线监测具有很高的潜力。使用改进的传感器将为智能电网中的变压器完整性提供解决方案，**确保系统可靠性。
