There are many series resonance manufacturers in the market nowadays. How to choose a series resonance device can be referenced from several aspects such as the manufacturer's years of experience, product application cases, and product reputation.
First, how to choose a series resonance device: Different high-voltage tests require different voltage levels, so it is necessary to formulate different plans according to your own needs (voltage level, test object). Generally speaking, series resonance manufacturers will develop a suitable technical solution based on customer requirements.
Variable frequency series resonance is suitable for AC withstand voltage tests of various large power transformers, power cables, steam and hydro generators, and other capacitive equipment. The voltage levels required for these tests must be strictly carried out regularly according to test procedures. Under power frequency conditions, due to the large capacitance of the test object or the high test voltage requirements, the power supply capacity of the test device also has correspondingly high requirements. Traditional power frequency withstand voltage devices often have large single-piece volume, heavy weight, are inconvenient for on-site transportation, and are not easy to combine arbitrarily, with poor flexibility. Therefore, series resonance test devices can be considered.
