As a new electrical student or a common man this questions comes in mind that why we prefer 3 phase power system. In recent years 3 phase electric wiring has become common and mostly used worldwide for power generation, power transmission, distribution and three phase engines or motors. A single-phase electric power supply is the… Read More »
A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. Stepper motor (or step motor) is in fact a brushless DC electric motor that divides… Read More »
A voltage regulator is used to regulate or stabilize the voltage level for specific purpose. Voltage fluctuations are never acceptable for any appliance or equipment, because it may damage the electrical appliances etc. When a steady, reliable voltage is needed, then voltage regulator is the preferred device. Despite varying inputs or load conditions a stabilizer… Read More »
In power generation the calorific value of fuel is prime factor. Use of fuels having high heat of combustion gives best output in terms of cost of electricity or energy generated. When we generate electricity in steam power plant we have to burn fuel like coal, petroleum oil or flammable gases. In thermal powers generation… Read More »
In Coriolis effect a mass moving in a rotating system experiences a force (Coriolis force) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important… Read More »
What is overvoltage: A sudden rise in voltage for a short duration on the power system is known as overvoltage or voltage surge. Overvoltage is always temporary that exist for short period but that may cause damage to the power system due to surge in voltages. There are many causes for occurrence of overvoltage condition,… Read More »
