Importance and corrections of Power Factor

  Power Factor Power factor is that the ratio between the KW and also the KVA drawn by an electrical load where the KW is that the actual load power and therefore the KVA is that the apparent load power. it's a measure of how effectively the present is being converted into useful work output and more particularly could be a good indicator of the effect of the load current on the efficiency of the provision system. Power Factor Formula All current flow causes losses both within the supply and distribution system. A load with an influence factor of 1.0 leads to the foremost efficient loading of the availability. A load with an influence factor of, say, 0.8, leads to much higher losses within the supply system and the next bill for the buyer. A small improvement in the power factor can reduce its losses. Because the loss is proportional to the square of the current. A convenience factor is the small amount of time a missing power is considered. So it is considered as reactive p

What Is Cogeneration | What is CHP Plant

  What is cogeneration? Cogeneration may be a very efficient technology to get electricity and warmth . It is also called Combined Heat and Power (CHP) as cogeneration produces heat and electricity simultaneously. Cogeneration supplies currently 11% of electricity and 15% of warmth in Europe. Using a fuel to simultaneously generate heat and electricity with one unit is more efficient and cost-effective than generating heat and electricity separately in two different units. The technology offers the following benefits for both its users and our society. CHP Plant Increased energy efficiency Cogeneration is up to 40% more efficient than the separate generation of warmth and power. Loweremissions Cogeneration saves per annum 200 milion tonnes of CO2 in Europe because of being very efficient. This equals the total emissions of 42.5 million passenger cars or 2.6 million trucks. Reduced energy costs Users of cogeneration enjoy higher efficiencies and thus need less fuel to hide t

Alternator | Working Principle

  What is Alternator? The working rule of an alternator is extremely simple. It is a bit like the essential principle of DC generator . It also depends upon Faraday’s law of electromagnetic induction which says the present is induced within the conductor inside a magnetic flux when there's a relative motion between that conductor and the magnetic field. Alternator This single turn loop can rotate opposite the ABCD axis a-b. Suppose this loop starts rotating clockwise. After 90o rotation the side AB or conductor AB of the loop comes ahead of S-pole and conductor CD comes ahead of N-pole. At this position the tangential motion of the conductor AB is simply perpendicular to the magnetic flux lines from N to S pole. 🛒 Buy now Click Below Image 👇 For understanding working of alternator allow us to believe one rectangular turn placed in between two opposite magnetic poles as shown above. Hence, the speed of flux cutting by the conductor AB is maximum here and for that flux cutti
