AC Test Transformer

AC test transformer is applicable for the AC voltage withstand test and partial discharge test of different insulation materials and electrical apparatus. They are widely used in the electrical apparatus manufacturers, electric power department, research institute and universities. The possibility of stacking several transformers allows reaching very high voltages by keeping a reasonable floor space.

Additional Product Information
