transformer at different load conditions: Thus‚ the different losses fall in to two categories Constant losses (mainly voltage dependent) and Variable losses (current dependent). The expression for the efficiency of the transformer operating at a fractional load “x” of its rating‚ at a load power factor of Cosθ2‚ can be written as ……… (1) Here S in the volt ampere rating of the transformer (V2‚ I2 at full load)‚ Pconst being Constant losses and Pvar the variable losses at full load. Pvar = (IFL)2

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis‚ understanding‚ thinking‚ and generically solving such problems resulting in an algorithm‚ verification of requirements of the algorithm including its correctness and its resource consumption‚ implementation (commonly referred to as coding[1][2]) of the algorithm in a target programming language.

ESSAY : "LOAD SHEDDING" Electricity load shedding in pakistan has incresed mainifold. Minister of water and power RAJA PERVAIZ ASHRAF assured that electricity load shedding would be done according to time schedule. He assured that electricity load shedding will finish by the end of the year 2009 but instead it is doubled what it was in the past year 2009. It is big failure of the government of pakistan. no country can make progress without electricity. Recent government

In Figure 3-10 the process of buying and planting flowers in the spring was shown using the same structures as the generic example in Figure 3-9. Describe some other process with which you are familiar using exactly the same logic. Answer: Student answers will vary widely. They should come up with processes that fit the generic logic shown in Figure 3-9. Some examples could include: making a dentist appointment

Load shedding was implemented to save money. It also saves pollution. Load shedding is what electric utilities do when there is a huge demand for electricity that exceeds the generation available. The alternative is to have a brown-out where the voltage is reduced. It costs a lot to have generators standing by just in case there is a surge of demand‚ and the operators of those generators expect to be paid whether they run the generators or not. An alternative is if there is a large consumer

edProblems caused by load shedding FALIURE OF INDUSTRIES: The first problem which happened due to load shedding is the failure of industry in Pakistan .This effect badly on all types of industry. In mini industry there is no alternative source of electricity so when load shedding started these industries stop their work. In big industry although they have a source of electricity but if they produce electricity from their own source then its cost becomes very high

An action (F) is a force (load) applied to the structure (direct action ) or an imposed deformation ( indirect action ) ex. Temperature effects. Actions are classified: a) by variation in time permanent actions G ( self-weight of structure). b) by their spatial variations: fixed actions ( self weight ) variable actions Q wind loads/snow. free actions which results in different actions accidental actions

Load Balancing in Cellular Network through Cell Breathing network structure being much dispersed‚ mobile AbstractIn cellular network‚ teletraffic continues to grow at a proliferating rate. Thus existing networks often encounter undesirable phenomenon like call drop due to overloading of cells. To overcome this problem‚ this thesis aims to perform load balancing using the technique of cell breathing in a novel way. Unlike previous works on cell breathing‚ where the radius of the overloaded cell was
