A testing device for visually detecting defects such as wire scratches and pinholes in coils and other wire materials.
This device is a testing apparatus that applies voltage to components such as stator coils for compressor motors in a vacuum state, allowing for the visual detection of wire defects and pinholes. By using a transparent acrylic vacuum chamber, it becomes easy to visually identify discharges from defective areas, enabling the rapid localization of defects that were previously difficult to pinpoint. Additionally, we can suggest combinations with measuring instruments according to the application, making this product suitable for a wide range of uses from product development to shipping tests. Composition: ● Vacuum chamber (made of acrylic) and controller ● Vacuum pump ● AC withstand voltage tester
