C eemanonline.com.t. e Cağrı Merkezi 66% PREUMINARY INFORMATION: Electrical compensation is a major scale subject that every business/facility is Included. The power factor should be compensated to change the reactive power up to some specific values since some reactive power limits are not good for consumption and generation of the electricity (this is a far large topic which also forms some subbranches, for more information and specification please research yourself). For this reason, it is an obligation to use a compensator system for both manufacturers (wind farms/hydroelectric power plants/etc.) and consumers (residents/factories/etc.). These issues are regulated by official directives. EXERCISE STEPS: A single-phase load has an active power of P = 2 kW at 180 V @60HZ and the power factor is coso = 0.75. This motor is compensated to coso = 0.85 using a parallel capacitor (the load is modelled as series…arrow_forward
