Bref: Follow along for a hands-on demonstration that highlights performance points of the XHDP Series 50KV VLF Hipot Tester. This video showcases how this Ultra Low Frequency AC High Voltage Generator performs AC and DC withstand voltage tests on large-capacitance items like power cables and generators. You'll see its intelligent protection features, direct high-side data sampling, and optional dielectric loss testing in action.
Fonctionnalités Des Produits Connexes:
  • Designed for AC and DC withstand voltage tests on large-capacitance items like cables and motors.
  • Features a single-link structure for ≤60kV models and a series structure for >60kV models to reduce weight and enhance load capacity.
  • Current and voltage data are sampled directly from the high voltage side for accurate measurements.
  • Intelligent protection functions automatically calculate overvoltage and overcurrent values, with an operation time of less than 20ms.
  • Utilizes a 150kV high voltage line output for safe and reliable operation.
  • Closed-loop negative feedback control ensures no capacity rise effect during output.
  • Includes optional DC and dielectric loss test functions to measure dielectric loss, capacitance, and insulation resistance.
  • Customizable output voltages of 30kV, 40kV, 50kV, 60kV, 80kV, and 90kV with various capability configurations.
FAQ:
  • What types of test items is the XHDP Series VLF Hipot Tester designed for?
    The XHDP Series is designed for AC and DC withstand voltage tests on large-capacitance test items such as power cables and generators. It is not suitable for small-capacitance or resistive items like zinc oxide arresters.
  • What are the customizable options available for the XHDP Series tester?
    You can customize the output voltage to 30kV, 40kV, 50kV, 60kV, 80kV, or 90kV. Additionally, you can choose to configure the tester with AC withstand voltage only, AC and DC withstand voltage capabilities, or AC and DC with dielectric loss testing capabilities.
  • How does the intelligent protection system work on this VLF tester?
    The intelligent protection system automatically calculates overvoltage and overcurrent protection values based on the test capacity and voltage, without requiring manual setting. It also protects against voltage and current mutations and can capture discharge situations, with a protection operation time of less than 20ms.
