Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.

Techimp HQ S.r.L
Techimp Voltage Tap Adapter is gender changer which allows the user to connect to the test tap (sometimes called power factor tap) of high voltage transformer bushings.While keeping the test tap well below the safety voltage level required by the manufacturer, the Tap Adapter lets the user to drain high frequency PD signals for diagnostic assessment of insulating materials.A synchronization signal can be derived as well.It is suitable for both single shot as well as continuous PD monitoring.Although it must be customized on the basis of the shape and dimension of the test tap (to be provided by the Customer), many models are readily available for the most established transformer bushings. A list of the presently available models is reported below.Several thousands of hours of operation are a guarantee of reliability and accurate design.
