80kV Very Low Frequency Tester 0.1Hz VLF High Voltage Withstand Test Equipment for Power Cable and Electrical Equipment
Product Overview
The SXCDP-80kV Very Low Frequency (VLF) AC Hipot Tester is designed for high-voltage withstand testing of electrical equipment with relatively large insulation capacitance.
The SXCDP-80kV integrates a digital frequency conversion system, microcomputer control, high-speed data acquisition, a 7-inch LCD touch screen, and background management software. It supports automatic voltage boosting, voltage reduction, measurement, and protection during testing.
Key Features
- 0.1Hz Very Low Frequency Testing
The tester supports very low frequency output at 0.1Hz, 0.05Hz, 0.02Hz and 0.01Hz, providing flexible testing options for different capacitive loads. - 80kV High-Voltage Output
With an output voltage of up to 80kV, the SXCDP-80kV is suitable for withstand testing of various high-voltage electrical equipment. - 7-Inch Touchscreen Operation
The system features a 7-inch LCD touchscreen with a user-friendly interface for convenient operation and monitoring. - Closed-Loop Feedback Control
A high- and low-voltage closed-loop negative-feedback control circuit is used to provide stable output without the stated capacitance rise effect. - Compact and Lightweight Design The compact design and relatively light weight make the SXCDP-80kV suitable for outdoor testing and on-site electrical maintenance applications.
