Product Description

Product Description

AC insulation testing provides the ideal solution to testing these lighter cables. AC insulation testing better simulates the

day-to-day stresses undergone by power systems, including frequencies like 50/60 Hz, without causing the insulation breakdown common in DC testing. Additionally, AC testing won't affect XLPE cables when used for over-potential testing, to an agreed acceptable insulation resistance value.

*Typical Application	AC withstand voltage test of: * 6 ~ 500 kV crosslinking polyethylene cable. * 35 ~ 500 kV GIS. * 10 ~ 500 kV switch, bus, casing.  * 10 ~ 500 kV power transformer. * 10 ~500 kV PT and CT. * generator. * 10 ~ 500 kV power capacitor.

The AC withstand voltage test of various large-scale power transformers, power cables, steam turbines and hydro-generators and other capacitive equipment must be carried out regularly in strict accordance with the test procedures.

Under the condition of power frequency, due to the large capacitance of the tested product or the high test voltage requirements, the power supply capacity of the test device has correspondingly high requirements.

The traditional power frequency withstand voltage device is often bulky and heavy. Heavy, inconvenient for on-site handling, inconvenient for any combination, and less flexible.

At present, a better method is to use the method of frequency conversion series resonance to carry out the withstand voltage test It can be used as a compensation capacitor for small-capacity samples, so that the resonant frequency can be completed within the range of 30-300Hz for AC withstand voltage tests of various power equipment.
