Power Frequency Hipot Test Equipment AC Withstand Voltage Test Set AC Dielectric Withstand Tester for Electrical Lab Use

The YDQ Series High-Voltage Withstand Voltage Test Device provides a flexible testing platform for assessing the dielectric strength of high-voltage electrical equipment. By applying controlled power-frequency AC voltage or DC high voltage, it helps users determine the insulation condition and withstand capability of the equipment under test.

A complete YDQ test system consists of a high-voltage boosting transformer and its control unit, including a control cabinet or operating console. The modular configuration allows the two sections to be matched according to different voltage and capacity requirements, making the system adaptable to various test environments.

The equipment is widely applied in substations, power plants, electrical factories, railway maintenance departments, metallurgical plants, mining enterprises, research institutes, and professional testing facilities. It can be used for insulation testing of transformers, HV switchgear, cables, insulators, bushings, and other electrical products and insulating materials.

For field testing and routine maintenance, the YDQ series offers a combination of stable operation, convenient handling, simplified maintenance, and safety-oriented design. Its relatively compact construction facilitates transportation and setup, making it suitable for both fixed high-voltage laboratories and mobile testing applications.

• Modular Matching System: The control section and boosting section feature a modular design, enabling users to configure a suitable test system based on required voltage and capacity.
• Compact Equipment Layout: Optimized engineering design reduces unnecessary bulk while providing convenient transportation, installation, and daily operation.
• Dual AC/DC Withstand Testing: One test system can support both alternating-current and direct-current withstand voltage applications, improving equipment utilization.
• Series Expansion for High-Voltage Tests: Multiple boosting units can be cascaded when a higher test voltage is needed, while a single unit can be used for conventional tests.
• From Manual to PC Control: Four control solutions—manual, electric, fully automatic, and industrial PC—provide different levels of operation and automation.
• Easy Test Result Handling: Optional printing and USB/PC communication functions make it easier to save, export, and manage test results for subsequent analysis.
• Configurations for Laboratory & Field Use: Different insulation structures, including oil-immersed, epoxy dry-type, SF₆ gas-insulated, and corona-free designs, can be selected according to the application environment.

• Power Utilities: Performs hand-over acceptance and preventive dielectric tests for substations, power distribution facilities and other utility installations.
• Electrical Insulation Verification: Tests the withstand capability of insulation systems used in transformers, HV switchgear, instrument transformers, cables, surge arresters and related equipment.
• Factory Testing: Supports type tests and production quality inspections for high-voltage electrical components and insulation materials.
• Industrial Maintenance: Provides an effective testing solution for periodic inspection of high-voltage systems in railway, mining, metallurgy, power generation and other industrial sectors.
• High-Voltage Laboratory Work: Suitable for insulation performance research, experimental testing and educational applications in universities, R&D centers and specialized laboratories.
