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.

How does hmu works in turbine engine?
In a turbine engine, the High-Pressure Compressor (HPC) compresses incoming air, increasing its pressure and temperature before it enters the combustion chamber. Here, fuel is injected and ignited, producing high-temperature, high-pressure gas. This gas expands rapidly and is directed through the turbine, causing it to spin and drive the compressor. The remaining energy in the exhaust gas is used to produce thrust, propelling the aircraft forward.
What kind of engine which uses water steam or heat has tur in it?
The engine you are referring to is likely a "steam turbine." A steam turbine converts the energy from steam, produced by boiling water, into mechanical energy. This process typically involves high-pressure steam passing through blades in the turbine, causing it to spin and generate power. Steam turbines are widely used in power plants and various industrial applications.
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?

What is the Airflow or a turbine engine?
Airflow in a turbine engine refers to the movement of air through the engine's various components, including the intake, compressor, combustion chamber, and turbine. This airflow is crucial for the engine's operation, as it facilitates the combustion of fuel and the generation of thrust. The compressor increases the pressure of incoming air, while the turbine extracts energy from the high-temperature exhaust gases, driving the compressor and producing thrust. Efficient airflow management is essential for maximizing performance and fuel efficiency in turbine engines.
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.
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.)

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

What causes the turbine of a hydro-electric dam to turn?
The turbine of a hydro-electric dam turns when water from the dam's reservoir flows through it at high pressure, causing the turbine blades to spin. This spinning motion is then transferred to a generator, where it produces electricity through electromagnetic induction.
What makes a jet engine turn?
A jet engine turns due to the combustion of fuel mixed with air in the combustion chamber, which produces high-pressure and high-temperature exhaust gases. These gases are expelled through a turbine, causing it to spin. As the turbine rotates, it drives the compressor at the front of the engine, which draws in more air, maintaining the cycle. This process generates thrust, propelling the aircraft forward.
