Abstract

Purpose – to study the durability of polymer films in electric field of direct current , define the type of the process of polymer films’ electric destruction under conditions of partial discharge suppression.
Research methods – experimental, results were processing by means of mathematical statistics.
The results – the electrical durability of micron thickness polymer films exponentially decreases with increasing of average field strength. Evaluation of studied polymer films’ electric strength based on the definition of their longevity allow to considered polypropylene film as the most electrically strong in these testing conditions.
Scientific novelty – experimentally was determined kinetic type of various polymeric dielectrics films’ electrical aging in electric field of direct current in terms of partial discharge suppression.
The practical significance – data on breakdown strength and durability of polymeric insulating films are useful for evaluating the efficiency limit of power capacitors and other devices with polymer dielectric films, forecasting the duration of their operability.
