Abstract
This paper presents an automated technique for monitoring the growth of electrical tree structures. Each stage of the propagation is recorded and the images analysed to give a series of measured and calculated values. Electrical tree growth was investigated using epoxy resin samples with point-plane electrodes. The test and material parameters were controlled or measured accurately for reproducibility. A point-plane separation of 2 mm and applied voltage of 10 kVrms were used throughout the tests
