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

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
