Cos phi calculator Trigonometry. Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest. 1 kva calculator 2 Power Factor – Definition, Importance, Calculation and Correction techniques. In an AC power system, the power factor is a very important parameter that defines how efficiently electrical power is being utilized by the load. It is a rational number between -1 and 1 but has no unit. The p.f of a system depends on the type of load present. 3 calculate power 4 To solve a trigonometric simplify the equation using trigonometric identities. Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. 5 Calculate apparent power S by multiplying load voltage V by load current I S = I × V. Find power factor from the formula power factor = P / S. Find the angle cos⁻¹(power factor) and draw a power triangle. Calculate reactive power Q from Pythagorean theorem: Q = √(S² - P²). 6 PF = |cos φ| = × P (kW) / (3 × V L-N(V) × I (A)) Apparent power calculation: |S (kVA) | = 3 × V L-N(V) × I (A) / Reactive power calculation: Q (kVAR) = √(|S (kVA) | 2 - P (kW) 2) Power factor correction capacitor's capacitance calculation: Q c (kVAR) = Q (kVAR) - Q corrected (kVAR) C (F) = × Q c (kVAR) / (3×2πf (Hz. 7 electrical calculator 8 Calaculate power factor, apparent power, reactive power and correction capacitor's capacitance. 9 Online calculator to size capacitors for power factor correction ; Initial value, Final value ; Power factor or Cos phi ; Sin phi ; Tan phi ; Power (kVA). 10 Free math problem solver answers your trigonometry homework questions with step-by-step explanations. 12
