Review of Space-charge Measurement using Pulsed Electro- Acoustic Method: Advantages and Limitations

The pulsed electro acoustic (PEA) technique is the most widely used method to measure space charge distributions in insulating materials. The PEA technique has undergone some advancement since the over twenty years it was first implemented such as in its spatial resolution and sensitivity. In this article a review of the technique was carried out and its advantages, limitations, progress and prospects were discussed.
