It's like 120 / 240V but also provides 240V 3 Phase for large loads (Machinery, etc.). It's often called Wild Leg of High Leg Delta.
- The HP to kVA formula is applied to electric motors that can be single-phase, In electrical terms, 1 horsepower equals 746 watts, but the conversion of Hp to kVA also requires knowing the power factor of the electrical device and efficiency. An industry standard average rating of 0.8 power factor (for motors) or 0.9 for other electrical.
- Single Phase Amps to kVA Calculation. Apparent Power in kVA = (Voltage in Volts x Current in Amperes) ÷ 1000. S = (V x I) ÷ 1000. Example: Find the kVA rating of a single phase transformer if the primary current rating is 120 amperes and RMS voltage is 120V. Solution: S = (120V x 125A) ÷ 100
- Watts to kVA calculator to convert watts to kilovolt-amps. Watts to kVA conversion is calculated based on watts, a power factor between 0 and 1 ; kVA (kiloVolt-Ampere) is a compounded unit. It's comprised of both electrical potential (Volts) and electrical current (Amps). 1 kVA is a frequently used unit; it represents 1,000 Volt-Amperes

Watts to volts calculator DC volts to watts calculation formula. The power P in watts (W) is equal to the voltage V in volts (V), times the current I in amps (A):. P (W) = V (V) × I (A). AC single phase volts to watts calculation formula. The power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V) Single Phase AC Power Sources / Analyzers - Above 1 kVA up to 5 kVA and other new and used AC Power Supplies products from Test Equipment Center The *easiest* way to get kVA for a single phase load is to measure the current it draws and the voltage supplied. kVA then is just current times voltage, divided by 1000. For three phase, use line to line voltage, and the highest phase's current reading and calculate.... kVA = Vline * Iline * sqrt(3) / 100 Watts (W), Kilowatts (kW) and Kilovolt Amps (kVA) are all units of electric power. Electricians tend to work in Watts and kW and we use kVA because kVA is used when talking about sizing, equipment for power generation and distribution
