Your question is a bit to vague to cover everything. You'd need to be specific about the running conditions. High T5 can be caused by overload of the unit as well as a variety of fault conditions. If the unit is running in T5 control mode (ie: full load) and experiences alarms or trips, it may be that T5 gain and integral values need to be adjusted to smooth out the over-shoot. Make sure that the fuel supply pressure to the unit is stable as the fuel system will have to counteract any changes in flow due to oscillations in supply pressure. This can introduce instability in the loop leading to high T5. If the unit is running below T5 in speed control (NGP) and suddenly trips on a very fast rise in T5, it's worth checking the speed probe and connections all the way back to the card. If there's a downward spike in the sensed speed due to loose connection or poor probe gap adjustment, the control system will react by putting in extra fuel to try to get back to the set-point, causing high T5 trip. This will very often be too fast to pick up on HMI or trigger log. There can also be problems with fuel valves that can cause poor temperature stability. Injector fouling is another possibility if your fuel quality is poor. Have a look at the T5 spread to see if they are all reading close to the same value. In very hot climates where the air inlet temperature go very high in the Summer months, you will hit the T5 control mode limit earlier than when the T1 air inlet temperatures are lower.
Hope that this helps.

What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
What is intermediate pressure turbine?
Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.
What is gas turbine protection?
The Gas Turbine Protection are; 1-High Vibration 2-Exh. temp. high 3-Lube oil temp. high 4-Low lube oil press. 5-Turbine air filter diff. high 6-Hyd. oil press. low 7-Exh. sprad temp. high 8-Fire
What is balance piston line of Turbine?
it is used balance axial thrust on turbine rotor due to admitting of high pressure steam in to turbine. it basic purpose is to save thrust bearing.
What is the uses of packing steam in turbine?
The main uses for packing steam in a turbine are to produce electricity and power. The steam creates pressure when in turn spins a turbine at very high rates of speed.
Can gas turbine engine be used in trains?
Gas turbine engine deals with high temperature and pressure. So it is difficult to use it. However if certain modifications are done in it , it can probably be used in trains. And if this is done the trains would be very high speed. as it is gasturbine engines which powers aeroplanes
Operation of diesel power plant?
Diesel fuel is combusted in a massive thing not unlike a massive car engine (not anything like a car engine but for simplicities sake I'm calling it an engine). The diesel turbine causes a magnet to move really fast inside some tightly wound and compact copper coils which create electrical energy. This energy is transported from the turbine to a "signal box of sorts" to be turned into high voltage, high frequency power ready for the distribution grid.
What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
How do you pressurize an aircraft?
There's an engine-driven compressor. On a turbine engine they pull bleed air off one of the turbine sections; on a piston engine plane it's an accessory to the engine. (Having said that, very few piston planes have pressurized cabins--they don't go high enough to need them.)
On the F108 engine the purpose of the HPT nozzle assembly is to accelerate the energy from the combustion gases to drive the?
High Pressure Turbine
How a generator operated by boiler?
The boiler heats water into steam. The steam is pressurized and fed into a turbine which causes it to rotate. As the steam turbine rotates, the connected generator rotates and produces electricity. Make Sense??? Please 'Recommend Contributor'
What is effect on turbine generator if frequency is high or low?
turbine will trip
What is power-to-weight ratio of steam turbine and gas turbine?
there is a mathematical formula to figure the actual power measured in Inchpounds of torque for both types of turbine engines. due to the light weight of the engine and the very high speeds in which they operate they are very efficient compared to other type of power plants generally the rough power to weight ratio of a typical aircraft turbine engine is around 85 to 95% output power compared to the actual weight of the type engine used.the exception to this would be a turbo-fan engine used on high speed aircraft which the power output is measured in footpounds of thrust
How does a steam engine differ from a steam turbine?
Technically a steam turbine is a particular type of steam engine. A classic steam engine usually refers to a reciprocating steam engine, which uses a piston and crank arrangement, where pressurised steam (from the boiler) forces the piston through its stroke, producing output power. A steam turbine produces power with pressurized steam expanding to high velocity, and impinging on turbine blades which produce rotational output power. A steam turbine can be considered similar to a windmill, although steam turbines typicaly rotate much faster, and often have many stages of steam expansion within a single machine.
What is turbine blade angel?
turbine blade angle is that angle with which,a high presseure & high temprature steam is made to empenge on it.
What has the author K P Leach written?
K. P. Leach has written: 'Energy efficient engine high-pressure turbine component rig performance test report' -- subject(s): Airplanes, Turbine-propeller engines
What causes high fuel consumption in a diesel engine?
There are several causes for high fuel consumption in a diesel engine. These include a difference in the weight of the vehicle, increased usage of air conditioning, and a difference in tire pressure.
