High Voltage Power Frequency Hipot Test Equipment AC Dielectric Test System

The YDQ Power Frequency Withstand Voltage Test Device is designed for high-voltage insulation testing of electrical equipment and insulating materials. It provides a practical solution for verifying whether the tested equipment can withstand specified AC power-frequency or DC high-voltage stress without insulation breakdown.

The system mainly includes a control cabinet or operating console and a high-voltage test transformer. Both units can be configured and combined according to the required output voltage, test capacity, and specific application conditions, providing greater flexibility for different testing projects.

• Wide-Ranging Configuration: A complete range of specifications is available, with the control console and high-voltage transformer capable of flexible combination to meet different testing requirements.
• Space-Efficient Construction: The equipment adopts an optimized structural layout, offering a practical balance between compactness, functionality, and ease of operation.
• AC/DC Testing Capability: Designed to perform both AC and DC withstand voltage tests, with a portable configuration suitable for different testing locations.
• Scalable High-Voltage Output: Individual transformer units can be used independently or connected in series to achieve higher test voltage requirements.
• Flexible Operation Methods: Supports manual adjustment, electric control, automatic operation, and industrial PC-based control for different testing scenarios.
• Test Data Connectivity: Printer, USB interface, and computer communication functions can be selected for convenient data recording, transfer, storage, and analysis.
• Application-Specific Insulation Options: Oil-filled, dry-type epoxy resin, SF₆-insulated, and corona-free configurations are available to adapt to different environmental and testing conditions.

• Substation Commissioning & Maintenance: Used for acceptance testing, commissioning verification and scheduled preventive withstand-voltage tests of power supply systems and substations.
• HV Equipment Dielectric Testing: Suitable for evaluating the insulation strength of high-voltage switchgear, transformers, CTs/PTs, surge arresters, cables, bushings and other electrical apparatus.
• Manufacturer Quality Control: Applied to factory inspection and type testing of insulating materials, high-voltage components and electrical equipment to verify dielectric performance.
• Industrial HV System Testing: Ideal for routine maintenance and insulation testing in power plants, railway systems, mining operations, metallurgical plants and other industrial environments.
• Academic & R&D Applications: Provides testing capabilities for universities, laboratories and research organizations engaged in high-voltage insulation studies and electrical engineering research.
