What are the principles and conditions for series resonance? Wuhan UHV specializes in producing series resonance, with a wide range of product selection and professional electrical testing. When looking for series resonance, choose Wuhan UHV. 

The series resonance withstand voltage test is a new method of high voltage testing that uses the inductance of a reactor and the capacitance of the test object to form an LC series circuit, adjusts the voltage frequency output of the variable frequency power supply, achieves series resonance, and obtains high voltage on the test object. It has been well received by experts and has been widely used at home and abroad. 

Currently, we have developed many detection instruments using the principle of series resonance, including series resonance test devices, cable variable frequency series resonance test devices, substation variable frequency series resonance test devices, and resonant boost devices for CVT inspection. 

According to the principle of resonance, we know that when the inductance value X1 of the current reactor L is equal to the capacitance value Xc in the circuit, the circuit reaches resonance state. At this time, only the circuit resistance R consumes active power in the circuit, while reactive power oscillates back and forth between the reactor and the capacitor of the test sample, thereby generating high voltage on the test sample. 

The conditions for generating series resonance:

X L =X C　　

Due to the high voltage generated by series resonance in L and C, it may cause damage to the breakdown of coils or capacitors. Therefore, in power engineering, series resonance should be avoided as much as possible, and it is particularly important to use series resonance testing devices to detect power systems.
