The YTB-20 Series is a rugged, professional-grade AC/DC high-voltage test system engineered for insulation testing in MV electrical products and substations. Designed with a two-piece layout, the operator controls the system safely from a distance using a control unit while the transformer operates under high voltage. This high-performance testing solution is perfect for evaluating the dielectric strength and insulation integrity of switchgears, transformers, circuit breakers, and more. Optional DC conversion via a rectifier makes the system highly versatile in both field and lab conditions.

Applications:

• High-voltage withstand testing of switchgear and circuit breakers
• Insulation testing for voltage and current transformers
• MV component testing in substations and utilities
• Routine high-voltage acceptance and type testing
• Safety validation of insulating materials and devices
