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.

电力变压器是重要的，也是最昂贵的设备之一，用于电能的传输和分配。尽管近年来他们的设计有了很大的进步，但致命的弱点仍然是隔热系统。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，导致计划外停机和**供电问题。当配电系统发生故障时，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，因此对配电系统的可靠性提出了极高的要求。通过准确地监测绝缘的状态（受潮、温度、振动等），可以在许多类型的故障成为严重故障和停机之前发现它们。** QPS在过去几年中取得的一些研究和发展成就导致了带有多层聚酰亚胺薄膜的相移光栅重涂传感器的**发展。这种光纤传感器旨在帮助工厂所有者监测充满油的变压器内部的湿度，振动和温度。提出的研究旨在分析现场测试数据记录并准确校准**传感器。所提出的研究将开发的知识和技术对**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，保证系统的可靠性。
