It is known that 1,2,3 benzotriazole (BTA) can effectively limit the oil flow electrification in oil-paper insulation used in HVAC transformers. But it is still unclear whether BTA is applicable to converter transformers. Thus, the effects of BTA on…
Ultra high voltage (UHV) converter transformer valve-side bushings are the key equipment indirect current (DC) transmission projects, and are subjected to high voltage and large current with large number of harmonics simultaneously. The electric…
Waxy crude oil presents poor flowability and complicated rheological behaviors near and below its gelation temperature. In recent years, high voltage direct current electric field has emerged as a novel approach to significantly reduce the viscosity…
