Wuhan UHV specializes in the production ofseries resonance (also known as power frequency withstand voltage test equipment). Next, we will share with you how to select the power frequency withstand voltage test equipment.

Overview of Series Resonance Test Device

The series resonance test device is a series resonance test device that uses tuned inductors and load capacitors to generate power frequency series resonance and obtain power frequency test voltage. A resonant series is composed of isolation and transformer, frequency and voltage regulation system power supply, excitation for transformer, reactor, and capacitive voltage divider. The capacitors and resistors of the subjects form a series resonant connection, and the voltage molecules are connected in series with the main body to measure the resonant voltage on the main body and provide overvoltage protection signals. The frequency modulation power output is coupled with the excitation transformer and the series resonant circuit to provide the excitation power for series resonance.  

Selection criteria for series resonance test device

The variable frequency series resonance test device is different from our general testing instruments. Its most distinctive feature is that the same set of equipment management can be directly used to study the AC withstand voltage test of different electrical engineering equipment, such as cross-linked cables, transformers, etc GIS、 Electric motors and generators, in addition to the typical and commonly used models provided in this selection catalog for users to choose from, usually require students to design a reasonable configuration plan based on the system user's sample range and experimental development requirements, to meet the testing method requirements of different countries, regions, users, and samples in society.
