“…It is extremely significant to note that electrical treeing is always complemented with the phenomenon of Partial Discharge (PD) [3] which may also be detected, measured and analyzed. Hence, it becomes important that the characteristics and properties of PD pulse data would inherently provide important clues into treeing related degradation mechanism.…”

Electrical treeing is a challenging prospect related to degradation mechanism in dielectrics that eventually leads to its breakdown. Treeing propagation depends on dielectric and electrode configuration thus leading to types such as branch, filamentary, bush etc. Though researchers have attempted a gamut of studies related to treeing, it is evident that appropriate choice of prognostic model is essential for prediction of ageing of insulation that emulate features such as dendrite length, channel width, space charge etc. Although studies related to treeing modeling have taken up depictions such as Diffusion Limited Aggregation, Field Limiting Space Charge etc. to obtain estimates of electric potential based on boundary value equations (Laplace and Poisson) utilizing tools such as Fractal Analysis, Cellular Automata etc., challenges such as space charge, inhomogeneity factor etc. continue to confront researchers. This research gives a detailed insight into a wide spectrum of studies related to treeing and ageing prediction assessment of insulation based on physical, electrical, numerical and analytical models developed thus far. This study also summarizes succinctly, the merits and limitations in each method and avenues for improvement. Finally, this research gives clues into important future opportunities related to methodologies for development pertaining to treeing prediction and ageing assessment.Recently the concept of CA has been effectively utilized by various researchers like [5]-[6], [11], [43]-[46] for their investigations related to the growth characteristics of electrical trees with distinct features of inclusion of dielectric inhomogeneity factor, effect of space charge, nano-composites etc. especially in case of solid dielectrics which are as specified in Table 6.

The effect of interface modification on electrical tree growth and breakdown of epoxy resin Abstract -This study investigates the effect of an interface on the lifetime of epoxy resin samples and the growth characteristics of electrical trees. Six sample types are presented; all having been prepared in the point-plane configuration using a needle -with a tip radius of 3μm-as the HV electrode. Most were molded in two parts producing an interface perpendicular to the field direction at the centre of the sample. Tests were carried out at 13 kV rms until sample breakdown occurred and sample images were taken at fixed one minute intervals during the test period. Results show that the interface modification affects electrical tree characteristics and improves the time to breakdown of the epoxy resin tested.
