The increasing demand for electric power over the last decades has urged the high voltage apparatus to operate at full load while the power system utilities are expected to provide high quality and reliable electric power. In order to avoid power outages and disturbances caused by equipment failures and outages, online, distributed, and low-cost condition monitoring, diagnostics, and protection are crucial in modern power systems. Passive, wireless sensors are emerging devices to enhance the existing condition-monitoring methods. These sensors do not require an internal power source. They are activated and interrogated by an external source of energy. Using an interrogator, a signal is transmitted to the sensor and the received signal reflected from the sensor is analyzed that contains information collected by the sensor. The objective of this project is to design, build, and test a switched oscillator that will significantly improve the performance of the interrogation system currently used by the researchers. Availability of the novel, passive, wireless sensors (that are also developed by the same research team) and the improved interrogation system will enhance power system utilities ability to monitor the condition of their high voltage equipment and systems.

在过去的几十年中，对电力的需求不断增加，促使高压设备满负荷运行，而电力系统公用事业公司期望提供高质量和可靠的电力。为了避免设备故障和停电造成的停电和干扰，在线、分布式和低成本的状态监测、诊断和保护在现代电力系统中至关重要。无源无线传感器是增强现有状态监测方法的新兴设备。这些传感器不需要内部电源。它们被外部能量源激活和询问。使用反射器，信号被发送到传感器，并且从传感器反射的接收信号被分析，该接收信号包含由传感器收集的信息。 该项目的目标是设计，建造和测试一个开关振荡器，这将显着提高目前使用的研究人员的询问系统的性能。新的无源无线传感器（也是由同一研究小组开发的）和改进的询问系统的可用性将提高电力系统公用事业公司监控其高压设备和系统状况的能力。
