1.Modification of AAL/BT VCB by providing in Built pressure gauge
TITLE: - Provision of in Built pressure gauge to check & trouble shoot in the

cases of DJ feedback fail/VCB stuck off/VCB Stuck on and during
schedule maintenance.

OBJECT: - There are several cases of pressure drop in VCB of all makes.

During schedule maintenance/trouble shooting of locomotive PRV/QPDJ
pressure setting is required to be check & adjust if any abnormality

noticed. In SEIL/GEC ALSTOM make VCBs, in built pressure gauge is
available with the range of 0-10kg/cm² and it shows the actual pressure of

the VCB. Where as in AAL/BT make VCBs, due to non availability of in built
pressure gauge, needs draining of air tank, isolation of Pneumatic circuit

to VCB and provision of external pressure gauge during every time of
trouble shooting/schedule maintenance of locomotive and it requires

additional man hours/maintenance. To avoid difficulty in trouble
shooting/schedule maintenance, it is proposed to arrange in built pressure
gauge in AAL/BT VCB with similar lines of SEIL/GEC ALSTOM makes VCB.
