![]() Long wire runs require thinner cable and save. The mega volt-ampere reactive is equal to line current I (A) in Amps times of voltage V (V) in volts and the sine of power angle(φ) divided by the 1,000,000. less amps + more volts less losses from wiring. MVAR is the very largest unit of reactive power and which is used in transmission line reactive power management. Calculation of Amps to Volts V (V) P (W) / I (A), which means that the voltage in Volts (V) is calculated by dividing the power in watts (W) by the current in Amps (A) V (V) I (A) x R (), which means that the voltage in volts (V) is calculated by multiplying the current in amps with the Resistance in Ohms (). Understanding your rate of use and your voltage level will help you make the right battery choices. A battery of this rating should last for 25 hours while producing power of 8 amps. ![]() Specifically, voltage is the measure of electric potential difference between two points whereas. For instance, if your battery is marked with a 1450 CCA, it represents 200 Ah. Volts and amps or ampere are two measures of electricity. Q (kVAR) = 3 x V (P-V) x I (A) x sin(φ) / 1000 Convert Amps to MVAR: But for a rule of thumb, you can divide the CCA by 7.25 to get the calculated Ah. Q (kVAR) = 1.732 x V (L-V) x I (A) x sin(φ) / 1000įor three-phase with phase voltage V (P-V), Power angle can be calculated from the power factor by using cos -1(pf)įor three-phase with line voltage V (L-V), /rebates/2fp2fquestions2fGE-100-Amp-240-Volt-Fusible-Outdoor-General-Duty-Safety-Switch-TG4323R2f2029786362f2&. Reactive power Q (kVAR) in Kilo Volt Amp reactive is equal to the 0.001 times of line current I (A) in amps and the line voltage V (V) (For three-phase, you have to consider 1.732 times of the Line voltage) and the sine of power angle. Q (VAR) = 3 x V (P-V) x I (A) x sin(φ) Convert Amps to kVAR: Learn More: Ceiling Fan Power Consumption Calculation, Power Saving Tips
