Yes. Three phase transformers are sometimesnot readily available whereas single phase transformers can generally be found in stock. Three single phase transformers can be used in delta connected primary and wye or delta connected secondary. They should never be connected wye primary to wye secondary, since this will result in unstable secondary voltage. The equivalent three phase capacity when properly connected of three single phase transformers is three times the nameplate rating of each single phase transformer. For example: Three 10 KVA single phase transformers will accommodate a 30 KVA three phase load.
Friction is main bad effect of a motor. Friction reduce a motor efficiency. Friction mainly create in a motor for it’s corrosion or speed ratio on spin. In a motor flywheel adjusted in drive wheel. In a gear ratio it mainly depends on gear and flywheel transfer energy on drive wheel. In a car or heavy load carrier vehicle used spring for reduce vibration and friction reduce generally use oil especially used in lubrication. For friction reduce one should firstly should select a metal which is help to reduce corrosion that’s means high resistance corrosion. Brake is also more important issue for a vehicle for it speed is slow down. There are three types of brake such as electromagnetic, disc and drum brake. Kinetic energy change to heat energy a vehicle speed reduce. Most of the car and vehicle use hydraulic brake which based in 6 steps and depends on 6 parts. These six parts are valve, road wheel, pedal, cylinder and boost. Electromagnetic brake is more popular for it’s more fa...
