摘要

Power frequency testing transformer typeYDJC-9000/2250 made in Shenyang Trans-former Works,is the power frequency testingdevice of the biggest capacity and the highestvoltage up to the present time.It plays an impor-tant part in the fields of improvement of 500 kVpower transmission equipments and provides thetest condition for 1000 kV electrical device incontaminated flash over,corona disturbance andelectrostatic induction etc.In April 1985,whencascade test carrying on in Wuhan,the
