Series resonant device? HVHIPOT specializes in the production of series resonance, with a wide range of product selection and professional electrical testing. To find series resonance, choose HVHIPOT.
A test device that generates AC high voltage using the principle of series resonance. Due to the problem of not being able to meet the test capacity when using high-voltage test transformers for high capacitance test samples (such as long cables, sulfur hexafluoride pipelines, capacitors, and large capacity generators), and the fact that large test transformers are used as power sHVHIPOTces for on-site voltage tests of the above test samples in the power system, transportation is also inconvenient. Therefore, sometimes series resonant devices are used instead of high-voltage test transformers.
The series resonant device adjusts its frequency within the range of 45-300Hz, making it particularly suitable for voltage withstand testing of on-site gas insulated substation equipment. This method is beneficial for improving the Q value and reducing the weight of the device.
The advantages of a series resonant device are: the entire device is detachable and lighter than a high-voltage test transformer; Good output waveform; After the withstand voltage breakdown of the test sample, due to detuning, the arc immediately extinguishes, making it difficult to repeat the breakdown and reducing the burn points of the test sample. Its disadvantage is that it cannot be used for wet flash and dirty flash tests.
The series resonance, series resonance test, and series resonance withstand voltage test devices are suitable for the handover and preventive testing of large capacity, high-voltage capacitive samples such as power cable series resonance, power transformer series resonance, generator sets (hydro generators or thermal power generators), motor series resonance, switchgear series resonance, GIS switches, etc.
