With the rapid development in EHV and UHV power transmission systems, the knowlegde about the performance of system insulations under switching impulses with very long front wave conditions namely from 1000 to 5000 us is most important for the optimum insulation design of the systems.　The conventional impulse generation technique, using CR impulse generator, becomes less effective, for such problems as failures of trigger in all generator stages and of decrease in generation efficiency, etc.　Under such circumstances, it is considered that the use of testing transformers to generate the switching impulses presents definite advantages over the conventional method.　From this stand point, the authors have commenced a study of this subject and have already reported the simplified equivalent circuit of testing transformers.　So, this paper is concerned with the results of some problems encountered on appling and discussion on them.　The results of the study will be thought useful for generation of the long front wave switching impulses using testing transformers.
