Canadian Society is highly dependent on the stability of the electrical power grid. Transformers are a critical component of the power system and the research in this Strategic Project grant aims to increase their efficiency, stability and lifetime. This can greatly increase overall power grid stability by maintaining consistent transformer operation, with the goals of avoiding catastrophic power failures and minimizing costs to the utility company. Powertech Labs (a BC Hydro subsidiary) has been a leader in researching techniques for transformer diagnostics, condition assessment and life extension. In particular, the degradation of the insulating paper at the windings of the electrical transformers is a key determinant of the technical end of life of a power transformer. This degradation generates specific marker compounds that can be used to diagnose the transformer's status. Ideally, these markers should be detected online, in the transformer during operation. However, this is currently not possible because there are no appropriate sensor materials that can detect the marker compounds. Thus, the target of this Strategic Project grant is to fill this critical need by developing a series of luminescent sensory materials that will respond to the presence of insulation degradation marker compounds in electrical transformers, based on vapoluminescent cyanoaurate coordination polymer materials recently discovered in the Leznoff group (which e.g. are sensitive to 1 ppb of ammonia) and patented by SFU. The synthesis of new [Au(CN)2]-based polymer materials, their analytical testing in air and immersed in transformer oil for sensitivity, response speed, marker compound concentration changes, and processing method will all be completed. The overall goal is to develop an in-line electrical transformer performance and maintenance monitoring system incorporating these new materials, which will represent a new, innovative manufacturing product for Powertech Labs, and the resulting improved electrical power grid will benefit all Canadians.

加拿大社会高度依赖于电网的稳定性。变压器是电力系统的重要组成部分，该战略项目资助的研究旨在提高其效率，稳定性和寿命。 这可以通过保持一致的Transformer操作来极大地增加整体电网稳定性，目的是避免灾难性电力故障并最小化公用事业公司的成本。 Powertech Labs（BC Hydro的子公司）一直是Transformer诊断、状态评估和寿命延长技术研究的领导者。特别地，变压器绕组处的绝缘纸的劣化是电力Transformer的技术寿命终止的关键决定因素。 这种降解产生可用于诊断Transformer状态的特定标记化合物。 理想情况下，这些标记应该在运行期间在Transformer中在线检测。然而，这目前是不可能的，因为没有合适的传感器材料可以检测标记化合物。 因此，该战略项目赠款的目标是通过开发一系列发光传感材料来满足这一关键需求，这些材料将对变压器中存在的绝缘退化标记化合物做出反应，这些材料基于Leznoff集团最近发现的蒸汽发光氰基金酸盐配位聚合物材料（例如，对1 ppb的氨敏感）并由SFU申请专利。 新的[Au（CN）2]基聚合物材料的合成、它们在空气中和浸入Transformer油中的灵敏度、响应速度、标记化合物浓度变化和处理方法的分析测试都将完成。 总体目标是开发一种采用这些新材料的在线电力Transformer性能和维护监测系统，这将是Powertech实验室的一种新的创新制造产品，由此改进的电网将使所有加拿大人受益。
