Wuhan UHV specializes in producingseries resonance (also known as series resonance test device). Next, we will share with you a comprehensive answer on how to select series resonance.

Introduction toseries resonant device

Series resonance is a necessary test equipment for insulation inspection of large capacity and high voltage power equipment in power preventive testing projects. It achieves the functional requirements of resonant boosting by adjusting inductance and frequency in combination. Variable frequency series resonance is composed of a control power supply, excitation transformer, high voltage reactor, compensation capacitor, and capacitor divider.

Selection requirements forseries resonance

Before purchasing a series resonance device, we need to understand the basic situation on site. Taking the voltage withstand test of power cables with many unknown parameters as an example, how to choose the capacity and maximum voltage of the series resonance test device based on the voltage level, cable length, and cross-sectional area has always been a problem for us. Today we will learn how to select the type of cable withstand voltage using series resonance.

Firstly, it is necessary to understand the length, cross-sectional area, and voltage level of the cable in advance, and calculate the maximum capacitance of the subject based on these known conditions. Then, with known electrical parameters, we can calculate the design capacity of the series resonant device. Today, Wuhan UHV will share with you the conventional configuration scheme of the cable series resonance test device based on our previous design plans and the actual operational experience of the after-sales department.
