hello..this is Himasnhu Khoriwal from Indian Oil working as Electrical Engineer.
We are having 3 gas turbines which are single shaft and of 30 MW rated capacity under standard conditions. now the problem is that BB5 and BB4 vibration probes are becoming out of order frequently in all the GTs.
the reason behind this according to me may be that since these vibration probes are located in the tunnel between load gear and turbine which has higher temperature as compared to the other probes areas. As measured through temperature gun, temp of tunnel was found to be nearly 250degc in all the three GTs.
Kindly suggest whether any relocation (like outside the tunnel or outside the compartment) for the same probes can be done, so that they are not exposed to such high temperature.
