Two quantities of the same type so he does not have a measurement or called Yenite is not unity. The ability factor in the exclusive physical loads is equal to one (1) because the actors in this case are the same as the phenomenon as there is no ability to be an inductive or capable. The ability coefficient is sorry for zero zero because zero actors in these loads. The same thing in the capacity is zero capacity for the same reason. The insuptive capacity is a capacity that arises because of rhythm and condensate files and has no specific place because they are frequented back and forth between the generator and pregnancy as they are in the form of SINE WAVE, which is an average that is equal to zero, which is not valuable or beneficial only to the file Or condenser as a result of a current traffic and the presence of voltage teams.
محول التيار أو ال current transformer . CTIslam Hesham
محولات التيار من اهم العناصر المستخدمة فى معظم مجالات الهندسة الكهربية فنجدها فى محطات الجهد العالى و المتوسط و ايضا نجدها فى دوائر التحكم و لوحات الجهد المنخفض
كما ان محول التيار له استخدام هام قد يغفل عنه البعض و هو clamp meter او ما يعرف بالكلامب امبير

Infinite bus bar is one which keeps constant voltage and frequency although the load varies. Thus it may behave like a voltage source with zero internal impedance and infinite rotational inertia.

Power in Watts
kW = kVA x Cosθ
kW = HP x 0.746 or (HP x 0.746) / Efficiency (HP =
Motor Power)
kW = √ ( kVA2– kVAR2)
kW = P = VI Cosθ … (Single Phase)
kW = P =√3x V x I Cosθ … (Three Phase)
Apparent Power in VA
kVA= √(kW2+ kVAR2)
kVA = kW/ Cosθ
Reactive Power in VA
kVAR= √(kVA2– kW2)
kVAR = C x (2 π f V2)
Power factor (from 0.1 to 1)
7. Power Factor = Cosθ = P / V I … (Single Phase)
Power Factor = Cosθ = P / (√3x V x I) … (Three Phase)
Power Factor = Cosθ = kW / kVA … (Both Single Phase
& Three Phase)
Power Factor = Cosθ = R/Z … (Resistance / Impedance)
XC = 1/ (2 π f C) … (XC = Capacitive reactance)
IC = V/ XC … (I = V / R)
IC = V 2 F C
IC = QC / V
IC = V / (1 / 2 π F C)
XC = V / IC
XC = 1 / 2 π F C
Required Capacity of Capacitor in Farads/Microfarads
C = kVAR / (2 π f V2) in microfarad
Required Capacity of Capacitor in kVAR
kVAR = C x (2 π f V2)
