Product Features

◆ High Voltage, High Power Output:** The integrated high-voltage pulse power supply for cable fault detection is capable of generating high-voltage, high-power pulse outputs, thereby meeting the requirements for efficient and accurate cable fault detection. This high-voltage, high-power output capability enables the power supply to penetrate the internal insulation layers of a cable and trigger discharge pulses, thereby achieving precise localization of cable fault points.

◆ High Control Precision:** Utilizing either digital or analog control methods, the integrated high-voltage pulse power supply achieves precise control over the width and amplitude of the output pulses. This high-precision control mechanism ensures consistent energy levels for every discharge event, thereby enhancing the stability and reliability of the detection process.

◆ Integrated Design:** This technology adopts an integrated design philosophy, consolidating the voltage boosting, rectification, and discharge components into a single unit. This results in a compact, lightweight device that is easy to transport and ideal for field operations. Furthermore, the integrated design simplifies the wiring and operational procedures, significantly improving both the usability and safety of the equipment.

◆ Enhanced Safety:** The integrated high-voltage pulse power supply is equipped with comprehensive safety features—including overcurrent and overvoltage protection—that automatically cut off the power supply in the event of an anomaly, thereby safeguarding the equipment. Additionally, the technology employs a safety isolation mode to ensure the safety and protection of the operating personnel.

◆ Wide Range of Applications:** This technology is applicable to the testing of cable faults in systems rated at 35 kV and below, covering a broad spectrum of fault types such as high-resistance faults, flashover faults, and low-resistance ground faults. Concurrently, it serves as an ideal solution for withstand voltage testing on cables, capacitors, motors, porcelain insulators, and similar components, representing a next-generation replacement for traditional power-frequency high-voltage power supplies.

◆ High Efficiency and Convenience:** The integrated high-voltage pulse power supply features both single-discharge and periodic-discharge modes, allowing it to adapt effectively to the varying characteristics of different cable faults. Moreover, thanks to its integrated design—which combines the voltage boosting, rectification, and discharge units—wiring and operation are remarkably simple and convenient. This empowers detection personnel to quickly and accurately pinpoint cable fault locations, thereby significantly boosting detection efficiency.
