to external fault. Switch OFF Battery few times again DJ closed same<br />
trouble experienced. So as per TLC advise HSIV kept on '0' and cleared<br />
the section. At 16.20 hrs GPL departure and at 18.10 hrs SCMN @. On<br />
@ SCMN power made TR.<br />
12 17‐Jun‐11 TLHR/BOB 27760 NKJ WCR Train KED dep. at 9.28 hrs and stalled at Km no 311/1 at 9.35 hrs due<br />
to DJ tripping and on checking LP found Q‐30 burnt. Same was<br />
informed to TLC and asked for relief loco at 9.45 hrs. Finally with the<br />
help of the relief loco no 23676/ET train section cleared to MZZ<br />

13 22‐Jun‐11 ME/NYG‐N BOX 27722 BNDM SER While passing STBJ at 22.55 hrs LP experienced OHE voltage raised up<br />
to 32 KV causing DJ tripping. Then he tried to close DJ but found SIV<br />
not picking up with H‐4(external fault lamp) glowing. Same is informed<br />
to TLC and after reducing of OHE voltage to 27 KV, LP tried to close DJ<br />
but found same problem. Then he tried as per TSD, kept HRAVT on "0",<br />
kept all auxiliary switches on "0" and tried to close DJ but no success.<br />
So LP made loco de‐energized for 25 mins and then tried to re‐energize<br />
the loco but no success. So as per the advice of TLC, LP cleared load up<br />

16 25‐Jun‐11 58502 23023 WAT ECoR At 16.15 hrs LP informed that train detaining at KM NO.174/13 ELS/VSKP: l/23023 was checked for smoke near RGR. 1) No relay Transformer Defective Material ECoR<br />
between SXV‐PBV due to loco trouble and LP demanded relief loco. OK targets were dropped. 2) RGR was found good and value was 2<br />
115/15 @ PBV. At 17.55 hrs MELE/15 detached and departure from<br />
PBV for section clearance. At 18.00 hrs 2VK @ PBV with relief loco. At<br />
18.05 hrs LP reported that after passing N/S between SXV‐PBV on<br />
closing DJ experienced loco tripping with heavy sound. On checking<br />
found smoke emission near RGR. No relay target dropped and DJ not<br />
MOhms. 3) ET‐1, ET‐2 gaps were 210 & 80 mm respectively. 4) VCB<br />
damping circuit was checked found 24.8, 24.9 Micro Farad (25 micro<br />
farad) 5) Capacitors near a0, a1, a2, a8 bushing were flashed<br />
condition. Its fixation bolts were flashed badly. 6) 991 cable<br />
connected to capacitor was flashed and conductors were melted. 7)<br />
closing hence demanded relief loco. At 18.05 hrs 26022 departure from 991 cable from capacitor to Q30 relay was completely damaged. 8)<br />
SXV which is nominated for 2VK working. At 18.25 hrs PBV@ and EOT Capacitor values were checked found (a) 0 Micro farad (b) 1.04<br />
with 2 VK at 18.25 hrs. At 19.10 hrs departure from PBV with dead loco micro farad (1 micro farad) 9) TFP BDV, DGA found satisfactory. (10)<br />

At the time of incidence the OHE voltage was 25.9 KV ( 16.0.12 sec,<br />
16.0.52 sec) (11) SMGR function was checked found normal. Due to<br />
heavy surge after passing neutral section, the capacitors of Aux<br />
winding got flashed and its cable was damaged resulted to smoke and<br />
tripping of loco Capacitance values check
