Recently, after-sales technicians from Wuhan UHV traveled to Guizhou to provide technical training for the customer. The customer in Guizhou purchased a series of equipments such as UHV Frequency Conversion AC Series Resonant Test System, GM-5kV Adjustable Insulation Resistance Tester Meter, etc. Due to the fact that the customer purchased more kinds of equipments and needed to apply them in the field experiment, the after-sales team of Wuhan UHV provided a four-day in-depth technical training, which was designed to enable the customer to fully grasp the way of using and the working principle of each piece of equipment.

The excitation transformer is used to stimulate the series resonance circuit. By adjusting the output frequency of the inverter controller, the circuit inductor L and capacitor C are resonated in series. The inductor L and capacitor C of the circuit are resonated in series by adjusting the output frequency of the inductor L and capacitor C. The inverter controller provides the power supply for the whole set of equipments and transforms the sinusoidal alternating current (AC) with a fixed amplitude and frequency from 380V or 220V to an AC power with adjustable amplitude and frequency. The output voltage of the inverter power supply is raised to a suitable voltage by means of an excitation transformer. High-voltage reactor L and test specimen C series resonance occurs, the resonant voltage is the voltage added to the test specimen C, that is, the test voltage, which can be adjusted by the output voltage of the frequency conversion power supply to realize the high-voltage test of capacitance test specimen C.

The site of the cable voltage withstand test, before and after the voltage withstand test need to do insulation test, the national standard requirements of the insulation resistance value should not be less than 70% of the factory test value of the product or not less than 100,000MΩ (20 ℃), we especially emphasize the safety of the test period, especially in the high-voltage test, safety is always the primary consideration. As a special reminder, when the test site is relatively empty, make sure that no one approaches the voltage-boosting equipment.

With the explanation of Wuhan UHV's after-sales technicians, customers can soon use the equipment independently to conduct tests. Wuhan UHV provides after-sales technical support, no matter when you bought our instruments, we will provide you with professional consulting services, we will reply to your letters or phone calls as soon as possible to help you solve any problems.
