Accurate Insulating Oil Breakdown Voltage Model Associated with Different Barrier Effects

In modern power systems, transformers are considered vital components that can ensure the grid’s continuous operation. this regard, studying breakdown in transformer becomes necessary, especially its insulating system. Hence, study, Box–Behnken design (BBD) was used to introduce a prediction model of voltage (VBD) for oil presence different barrier effects point/plane gap arrangement with alternating current (AC) voltage. Interestingly, BBD reduces required number experiments and their costs examine parameter effect on existing VBD. The investigated variables were location space (a/d)%, relative permittivity materials (?r), hole radius (hr), thickness (th), inclined angle (?). Then, only 46 experiment runs build five variables. verified based statistical study some other runs. Results explained influence obtained results indicated designed provides less than 5% residual percentage between measured predicted findings illustrated high accuracy robustness proposed predictive linked diverse effects.
