FAQ
What materials is the VBT-50KV specifically designed to evaluate?
The VBT-50KV is a professional-grade instrument specifically designed for piezoelectric ceramics. It is utilized to evaluate their dielectric strength by accurately testing the maximum voltage at which electrical breakdown occurs, as well as verifying the maximum safe operating voltage under normal conditions.How does the system ensure operator safety and prevent equipment damage during 50kV testing?
Operating at 50kV requires extreme safety measures. The VBT-50KV resolves this by incorporating advanced high-voltage interlock breakdown isolation technology. Furthermore, it is equipped with intelligent breakdown protection and an instant breakdown alarm function, ensuring that the system reliably shuts down upon sample failure to protect both the operator and the core generator.Why does the system use a silicone oil environment for measurements?
High-voltage testing in standard air often leads to premature surface flashover, which corrupts the dielectric strength data. By submerging the samples in a specialized silicone oil bath with precise temperature control (from Room Temperature up to 200°C), the VBT-50KV eliminates air arcing, guaranteeing that the true breakdown voltage of the material is recorded.What testing modes are available for different experimental requirements?
To accommodate diverse research and quality control standards, the VBT-50KV offers multiple intelligent step-up modes, including a uniform speed breakdown mode (for determining ultimate limits) and a steady withstand voltage mode (for reliability verification).
