Rich inspection content such as "pressure test" and "inter-layer dielectric strength test"! Introducing the inspection methods for transformers.
We conduct intermediate inspections, final inspections, and shipping inspections for transformers. In the "withstand voltage test," we check whether the insulation between the test subject and other parts maintains appropriate insulation capability. In addition to this, there are other tests such as "inter-layer dielectric strength test," "insulation resistance test," and other items tested during prototype production based on the validity of the design and customer requests. 【Inspection Contents】 ■ Withstand Voltage Test ■ Inter-layer Dielectric Strength Test ■ Insulation Resistance Test ■ No-load Current (Excitation Current) / No-load Loss (Iron Loss) ■ No-load Voltage *For more details, please refer to the PDF document or feel free to contact us.
