High-voltage hipot tester BDV5

DCAC

Overview BDV Test Bench is a high-voltage test bench designed for Breakdown Voltage (BDV) validation and for verifying the performance of the electrical insulation of high-voltage components. The system provides a controlled and reproducible test environment particularly suited to research and development, material characterization, design optimization and early detection of potential insulation weak spots. The bench performs BDV tests in AC or DC on a wide range of components. The component is placed in dedicated tooling and connected through HV clamps and conductive media; voltage is then applied according to a programmable ramp with automatic breakdown voltage detection.

Applications The system is intended for electrical insulation verification and characterization of dielectric limits for components such as electric motor stators, hairpins, enamelled wires, HV connectors, wiring harnesses and immersed or encapsulated components. Test parameters are configurable through dedicated recipes and include ramp rate, test duration and current threshold. Breakdown voltage, leakage current and test duration are recorded during the test.
