HZDP-80KV 80kV VLF AC Withstand Voltage Test Equipment
Huazheng HZDP-80KV 80kV VLF AC Withstand Voltage Test Equipment The ultra-low frequency insulation withstand voltage test serves as an alternative to the power frequency withstand voltage test. For large and medium-sized generators, motors, power cables, and similar test objects, the high capacitance in their insulation layers requires the use of a high-capacity test transformer or a resonance transformer during the power frequency withstand voltage test.

Advantages Of HZDP-80KV 80kv VLF AC Withstand Voltage Test Equipment
In response to the actual conditions of China's power system, the National Development and Reform Commission has established the industry standard for VLF (0.1Hz) withstand voltage testing for 35kV and below XLPE-insulated power cables. In 2004, the industry standard DL/T 849.4-2004, outlining the general technical conditions for VLF and high-voltage generators, was introduced in China. While DC voltage withstand test equipment offers advantages such as small size, light weight, and low cost, DC voltage testing is also the most destructive to the insulation of the tested object. Therefore, the latest national regulations on preventive testing of electrical equipment stipulate that DC high voltage should no longer be used for voltage withstand testing, and AC voltage testing is recommended instead.
Our company's new generation of 0.1Hz VLF high-voltage generators utilizes the latest power electronic components and ARM7 microcontroller technology, further reducing equipment volume and weight, ensuring ease of operation, and providing more stable performance. This overcomes the shortcomings of the first generation of mechanical boosters, such as short service life, high failure rates, and large size.
