The Power The power in real life can be divided to three type: 1 - KW is working power ( actual, real or active power), it’s the power that actually powers the equipment and performs useful work. 2 - KVAR is reactive power, it’s the power that magnetic equipment need to produce the magnetizing flux. 3 - KVA is Apparent power it’s the vectorial summation of KW and KVAR.

The power factor (PF) The power factor is the ratio of working power to apparent power. P. F. = KW / KVA

Causes of poor power factor The poor power factor came from Inductive load The inductive loads (which are sources of Reactive Power (KVAR) ) include: § Industrial heating furnaces § Induction motors § Welding equipment § High intensity discharge lighting ( HID)

Disadvantages of poor power factor will required more unnecessary load current. v Over heat in the equipment ( conductors, devices) v low efficiency for connected devices. v High voltage drops in alternators, transformers and supply network. v High power consumption which need increase the generations. v

- The purpose of power factor correction - PRESERVATION OF THE ENVIRONMENT: IN CASE WHEN THE CUSTOMER LOAD REDUCE THE POWER FACTOR, THIS REQUIRES AN INCREASE IN FUEL BURNING PROCESSES, WHICH LEADS TO AN INCREASE IN THE SMOKE PRODUCED FROM COMBUSTION PROCESSES. - REDUCE OF CONSUMERS LOSSES: IN THE CASE OF LOW OF POWER FACTOR, THE CUSTOMER WILL SUFFERS FROM WEAKNESS IN THE PERFORMANCE OF ELECTRICAL DEVICES, LEADING TO REDUCED LIFE SPAN, AS WELL AS AN INCREASE IN THE NEED FOR MAINTENANCE.

Reactive Power (KVAR)

Relation between KVAR and PF

KVARH • • The EWA going to charge the KVARH for non domestic with MD >1 MVA ( stage 1). The Excess KVARH to be charged to the customer The KVARH will be calculated depending on the actual consumption that will be recorded from energy meters. The EWA will charge 16 files per KVARH

KVARH Calculation § § The EWA will get the actual KVARH consumption from energy meters. If PF >= 0. 9 : No extra charge § If PF < 0. 9 : customer will be charged § The KVARH at PF=0. 9 will detected from total KVARH - KVARH at 0. 9 PF = 0. 484 * KWh consumption § § The charged KVARH = consumption KVARH – KVARH at 0. 9 PF The average PF will be calculated from consumption of both KWH and KVARH

Power factor correction The main function for power factor correction ( using the capacitor banks) is to improve the PF which will reduce the KVAR amount. There are many benefits for PF improved: • Reduced power consumption • Lower electricity bills • Voltage drop reduction in long cables • Increased life expectancy of electrical equipment
