IGBT Loco Issues:
As IGBT Traction Converters used in 3 Phasers are built by three firms namely ABB, BHEL and BTIL and assembled by CLW in the 3 Phase Locomotives so the issues have been addressed to the specific firm whose "IGBT Traction Converter" is being installed in the Loco.Please see the three attached "Excel Spreadsheets" to know about the Issues regarding IGBT Locomotives(3 Phaser specially WAP7,WAG 9, WAG 9H & WAG 9i). You can see the "Comment of RDSO" against "Each Issue" addressed to "ABB"in the last column of first Excel Spreadsheet and in other two excel spreadsheets you can see the "status of the issue" and "Firm's Comment about the issue" in the last column of the Excel Spreadsheet .
Attached Excel Worksheets:
3 IGBT LOCO ISSUES WITH ABB.xls(Extracted from the Official Website of CLW)
4 IGBT LOCO ISSUES WITH BHEL.xls(Extracted from the Official Website of CLW)
5 IGBT LOCO ISSUES WITH BTIL.xls(Extracted from the Official Website of CLW)
*** Please download the "Excel Spreadsheets" for seeing the issues of IGBT Locos.
This is "A Compact Information" about 3 Phase Locos(Specially: WAP 7, WAG 9, WAG 9H & WAG 9I) presented here from the Official Website of CLW.
