MEMS-based acousto-magnetic Partial Discharge detector based on on-chip planar inductors
High-voltage devices are the key to efficient, high-performance, safe, and reliable energy transmission; however, they could be exposed to several failure types. Indeed, when the electric field across an insulator exceeds the dielectric strength, an electric discharge, in the form of a spark, occurs. The discharge is called partial discharge (PD) when it does not short-circuit the whole insulation. Studies show that over 85% of disruptive failures in high-voltage (HV) and medium-voltage (MV) equipment (power transformers, gas-insulated substations (GIS), motors, cable installations, etc.) are PD-related. Therefore, PD prevention and detection are essential to ensuring reliable and long-term operation of the HV equipment, often very expensive, used by electricity companies. Given the importance of PD monitoring, our work focuses on the development of a novel generation of MEMS-based PD microsensors. MEMS, or Micro-Electro-Mechanical Systems, technologies combine cutting-edge approaches from microelectronics, semiconductors, and several micromachining techniques, allowing the realization of complete Systems on a Chip (SoC), grouping mechanical and electronic micro-components. Hence, this proposal will address the development of a new generation of low-cost, MEMS-based electrodynamic (or inductive) microsensors to be used to accurately measure the PD presence and location in costly MV/HV facilities, instruments, and equipment.

Project objective
Partial discharge (PD) may lead to the degradation of insulating materials and affect the lifetime of high voltage (HV) equipment. Thus, the detection of PD is an efficient and practical method to evaluate dielectric defects at an initial stage. Given the importance of PD detection, this proposal will address the development of a new generation of MEMS-based low cost, electrodynamic (or inductive) microsensor to be used to accurately detect the presence of a PD in costly electrical conductors and MV/HV equipment. The innovative idea in this proposed method lies in exploiting both electromagnetic radiation emissions, in the form of radiofrequency waves, as well as the acoustic emissions, in the form of ultrasonic waves, which mark discharge phenomena in high electric voltage cables, as an example. Besides the high sensitivity guaranteed by the use of MEMS technology, this novel method will allow us to benefit from the advantages of both electrical and acoustic methods, and overcome their weaknesses.
