electric torque=?=pxE
when the dipole is in uniform electric field,ie parallel to the fld,then net torque=0  as for this position ?=0 ,so the dipole will be in equilibrium.
in nonuniform el fld also when the dipole is along the increasing direction of thew electric fld, then the torque will be 0 on it.ie it will be in equillibrium.
