Partial Discharge Simulation Device for Cable Training. This device (Model: MS-GTU-PD806) is specialized equipment developed by Wuhan Musen Electric Co., Ltd. for teaching and practical research training in the field of electric power engineering. Its core function is to realistically simulate various partial discharge (PD) phenomena that may occur during the operation of high-voltage electrical equipment, such as power cables. The system accurately replicates PD defects—stemming from causes like external damage or insulation aging—in cable terminations, intermediate joints, and the cable body itself.
By precisely simulating typical insulation defects such as air-gap discharge, floating-electrode discharge, surface discharge, and particle discharge, the device provides a safe, intuitive, and repeatable experimental platform for courses such as "High Voltage Technology" and "Condition Monitoring and Diagnosis of Electrical Equipment," fully complying with relevant national standards and industry guidelines.

High-Voltage Power Supply: A partial-discharge-free high-voltage source is housed within the enclosure; it feeds the high-voltage signal into the discharge model via an internal coupling capacitor, serving as the core component for generating standard partial discharge signals.

Discharge Model Chamber: Contains interchangeable electrodes representing typical discharge models (point-to-plane, floating, air gap, particle, and surface discharge). Users can control the electrode's vertical movement via an external handle to engage or disengage it from the internal high-voltage conductor, thereby selecting and activating specific discharge types for experiments.

Multifunctional Sensor Interface Zone: Integrates interfaces for high-frequency, UHF, and ultrasonic sensors, supporting simultaneous or comparative training setups for various partial discharge detection techniques, such as pulse current, UHF, and ultrasonic methods.

Intelligent Control and Display Panel: Consolidates functions including power control, voltage regulation (0–250V input corresponding to 0–100kV output), discharge parameter configuration, and displays for voltage and discharge magnitude, all via an intuitive user interface.

Safety Enclosure: Features a fully enclosed, all-metal structure that completely encapsulates the high-voltage components, ensuring absolute operator safety. The robust enclosure is dustproof and rainproof, making it suitable for diverse indoor and outdoor teaching environments.
