The importance of series resonance test device

HV Hipot Electric Co., Ltd. specializes in producing series resonance (also known as series resonance test device). Next, we will share with you the importance of series resonance test device.

In the operation and maintenance of power equipment, preventive testing is an important link and an effective means to ensure the safe operation of power equipment. This is because electrical equipment is affected by various factors such as electric field force, operating temperature, air humidity, and corrosive gases during operation, and the insulation performance will continuously weaken, which may shorten the service life of electrical equipment. Therefore, corresponding electrical equipment maintenance measures need to be taken to maintain the normal operation of power equipment.

What is the importance of using a variable frequency series resonant withstand voltage test device for power equipment with large capacitors such as cables, high-voltage switches, transformers, etc., in order to timely detect hidden dangers in operating equipment and effectively prevent accidents or equipment damage? This article provides answers for you.

Only the series resonance withstand voltage test device can meet the insulation performance preventive test of large capacity power equipment. Due to the high voltage level of large capacity power equipment and the need for large capacitance, general power frequency withstand voltage testing devices are no longer able to meet the withstand voltage testing requirements of large capacity power equipment. Due to its greatly reduced capacitance, the power supply required for the test of variable frequency series resonance is only 1/Q of the test capacity (Q is the quality factor). Therefore, using a variable frequency series resonance test device makes it easier to boost the voltage to the required power level for the test, thus effectively preventing the test of the sample.  

It is safer and more reliable to use a variable frequency series resonant withstand voltage test device for the withstand voltage test of large capacity power equipment. Due to the strong protection function and good stability of the variable frequency power supply, the testing device has several testing modes, including fully automatic testing, automatic tuning, and automatic boosting, as well as fully manual testing, manual tuning and boosting, and semi-automatic testing, automatic tuning, manual boosting, or manual tuning and automatic boosting.


The importance of using a variable frequency series resonant withstand voltage test device for insulation and voltage preventive testing of large capacity power equipment such as cables, high-voltage switches, transformers, generators, etc. is reflected in its practicality and safety.
