Dear sir In a 15 A armature and 3A field 6RA70 regulator, field current is not developing while switching on power. P076.02 = 100% P078.02 = 400v P082 =. 3 P102 =0.56A P103= 0.1A P253= 1 precontrol active P263=1 from emf I have given 2 ph supply of R and B 415v ac supply to field. But after power ON, only fileld SP at r036 is showing 99.9% ....but at r035 field act value is showing only zero....but full current of 1.6 A is flowing. That why i put a lamp of 500w instead of motor field. Even after 3 min, no field current is showing. But once if iIdo P051 =22, immediately current starts developing....but very slowly to reach 99 % after 2 min and it is oscillating between 97 to 102% at r035. Again if we switch of control..then power.... After 2 min if again power is On, same problem gets repeated. I changed the bottom Thyristors card. No improvement. So pl kindly help me Predeepkumar .Salem Steel Plant. Salem13
