The place where power is generated, step upped & transmitted to remote places, called a Power plant. Power planets are Six types. 1. Thermal power plant 2. Hydro power plant 3. Nuclear power plant 4. Gas power plant 5. Solar power plants 6. Wind power plants 1. Thermal power plant: Where electricity is generated using of steam from coal heat energy. chemical energy of coal is converted to heat energy in a furnace. this heat energy is using to boil water and used for generate steam in a boiler. this steam is further heated to generate for super-heated steam which contains high energy level. this super-heated steam travelled from boiler to a turbine and this steam pusses the wings of turbine so that it is generated mechanical forces. Due to these forces rotation forces generated on turbine shaft and shaft is start to rotate as per our requirement.We can control the speed of shaft with using governors. this shaft is coupled with generator shaft and power has been transf...

CABLE SIZING CALCULATION: Why do the calculation? The proper sizing of an electrical (load bearing) cable is important to ensure that the cable can: · Operate continuously under full load without being damaged · Withstand the worst short circuits currents flowing through the cable · Provide the load with a suitable voltage (and avoid excessive voltage drops) · (optional) Ensure operation of protective devices during an earth fault When to do the calculation? This calculation can be done individually for each power cable that needs to be sized, or alternatively, it can be used to produce cable sizing waterfall charts for groups of cables with similar characteristics (e.g. cables installed on ladder feeding induction motors). General Methodology All cable sizing methods mo...
