Recently, a power engineering enterprise in Panama purchased a 40kV ultra-low frequency high-voltage generator made in China for the insulation withstand voltage test of large cables and generators. This equipment adopts digital frequency conversion technology and microcomputer control to achieve full automation of voltage rise, measurement and protection. It is easy to operate and provides accurate data.

The product has significant advantages: the output frequency covers 0.1Hz, 0.05Hz, and 0.02Hz, with strong load-carrying capacity and suitable for high-capacitance test samples. Dual overcurrent protection for high and low voltage and a 1.1 times overvoltage protection mechanism, with an action time of less than 20 milliseconds, ensure the safety of the test. The high and low voltage closed-loop negative feedback circuit eliminates the capacitance rise effect, and the voltage waveform distortion is ≤5%, making the output more stable. In addition, the equipment is small in size and light in weight, supporting both indoor and outdoor operations. The LCD screen displays waveforms in real time and supports printing reports, meeting the on-site rapid detection requirements.

This procurement highlights the technical strength of China's high-end testing equipment, helping Panamanian customers enhance the maintenance efficiency of power facilities and reduce testing costs. The equipment strictly complies with the standards of the International Electrotechnical Commission and provides reliable solutions for the power industry in Central America.
