Exciter transformer protection:equip piezoresistor for each HV output,exciter transformer's input and output terminal connects with the ground via zinc oxide arrester,this mehods can protect the operator and the equipment itself when test object breakdown.Structure:steel housing,HV bushing equips on the oil tank ,equips wheels.movable ,oil tank is shell-type,lead out the low voltage with porcelain bushing.Each terminal is lead out by relative voltage grade bushing.HV bushing lead wire go through isovolumetric capacitance core,exterminal insulation is fiber glass bushing.Bushing has corona ring .Oli tank has oil conservator to make sure the capacitance core in the oil.HV bushing can gurantee 30kV corona free .Exciter transformer insulation characteristic:Exciter transformer insulation level will determin transformer's safety work and insulation ageing speed.To guarantee no flashover which coming from external,electric potential raise and cause damage to the main insulation and minor insulation.We will also set insulation layer between HV windings and turn-to-turn.Winding is cylinder type.Capaiactance is determin  by the winding's area .When design,we'd try our best to make sure the top and bottom has the same ares,and compensate with electrostatic shield to improve the initial voltage distribution.Winging skeleton is made of compound insulation tube:can get down partial discharge and shielding the iron coil .
