The customer I am working with has installed a new 23QT-1 Lube Oil Heater on a FR6B gas turbine unit. They believed they had a faulty element but have just found the same problem as previously.
When the temperature switch enables the immersion heater to switch on, it trips on the heaters thermostatic protection shortly after. As the heater is an immersion type, I would expect that it would be designed to operate immersed in oil. As normal for these units the lube oil heater is installed in a thermowell and hence operates in an air space.
I have discovered on an earlier thread that there may be a GE TIL with regard to the wiring terminations (star v delta) that may pertain to this issue.
Can anyone supply/direct me to this til or at the least let me know its number so that I can continue to look for it.
thanks
