Turibne 125 V DC Ground

Turibne 125 V DC Ground

Turibne 125 V DC Ground

(OP)
Greetings,

We have GE frame five gas turbines and we are suffering from intermittent 125 VDC ground. The DC ground is existed as long as the turbine is running, as soon as soon the turbine is down the ground disappeared. Sometimes the ground is going on and off while the turbine is running, yet, it will not be existed as soon the turbine is down. There is only two wires that carry the DC from the battery to all DC devices in the turbine which make it almost impossible to detected it.

On of the proposal we are studying is having a separate DC circuit for each DC device in the turbine. Yet, my question is that: is there any type of equipment or a device that can detect the DC ground in a turbine while the turbine is running?? Is there any DC grounding online monitoring system available in the market that can be used in the gas turbine???

Aramcawee,

I have answered your identical post in another forum. Please don't double-post.
