Calculation Formulas

Single phase amps to kVA calculation formula

The apparent power S in kilovolt-amps is equal to current I in amps, times the voltage V in volts, divided by 1000:

S_(kVA) = I_(A) × V_(V) / 1000

3 phase amps to kVA calculation formula

Calculation with line to line voltage

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to line RMS voltage V_L-L in volts, divided by 1000:

S_(kVA) = √3 × I_(A) × V_L-L(V) / 1000

Calculation with line to neutral voltage

The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to neutral RMS voltage V_L-N in volts, divided by 1000:

S_(kVA) = 3 × I_(A) × V_L-N(V) / 1000

Example Calculation

Problem: Calculate the apparent power of a single-phase system with 15 amps current and 230 volts.

Solution:
Given: I = 15 A, V = 230 V
Formula: S = I × V / 1000
S = 15 × 230 / 1000
S = 3450 / 1000
S = 3.45 kVA

Answer: The apparent power is 3.45 kVA

FAQS

How many VA to 1 kVA?

1 kVA equals 1,000 VA (volt-amperes). This is a direct conversion where kVA represents kilovolt-amperes, meaning 1,000 times the base unit VA. Simply multiply kVA by 1,000 to get VA, or divide VA by 1,000 to convert to kVA.

How many VA is 1 amp?

VA equals amps multiplied by voltage (VA = A × V). For example, 1 amp at 120 volts equals 120 VA, while 1 amp at 240 volts equals 240 VA. The actual VA value depends on the system voltage being used.

What is 75 VA in amps?

Amps = VA ÷ Voltage, so 75 VA equals 0.625 amps at 120V or 0.31 amps at 240V. To calculate amps from VA, divide the VA value by your system’s operating voltage. The amp value varies depending on the voltage level in your electrical system.

How many kVA in 1 amp?

kVA = (Amps × Voltage) ÷ 1,000, so 1 amp equals 0.12 kVA at 120V or 0.24 kVA at 240V. The kVA value for 1 amp depends on your system voltage. Higher voltage systems produce higher kVA values for the same amperage.

Amps to kVA formula 3 phase?

3-Phase kVA = (√3 × Amps × Line Voltage) ÷ 1,000 or kVA = (1.732 × A × V) ÷ 1,000. This formula accounts for the square root of 3 (1.732) multiplier used in three-phase electrical systems. For balanced loads, this gives you the total apparent power in kVA.

Volt amps to VA and kVA calculator?

VA = Amps × Volts, and kVA = VA ÷ 1,000 or kVA = (Amps × Volts) ÷ 1,000. Volt-amps (VA) represent apparent power, while kVA is simply VA divided by 1,000. Use online calculators for quick conversions or apply these formulas for manual calculations.

Difference between kVA and kW?

kVA measures apparent power while kW measures real power consumed by loads. The relationship is kW = kVA × Power Factor. kVA includes reactive power that doesn’t perform useful work but still flows through electrical systems.

Amps to kVA calculator?

Single-phase: kVA = (Amps × Volts) ÷ 1,000. Three-phase: kVA = (√3 × Amps × Volts) ÷ 1,000. Online amps to kVA calculators use these standard electrical formulas to provide instant conversions. Input your amperage and voltage to get accurate kVA results.

kVA to amps?

Single-phase: Amps = (kVA × 1,000) ÷ Volts. Three-phase: Amps = (kVA × 1,000) ÷ (√3 × Volts). Converting kVA to amps requires knowing your system voltage and whether it’s single-phase or three-phase. The three-phase formula includes the 1.732 factor for balanced loads.

kVA to amps chart?

A kVA to amps conversion chart shows common electrical values at standard voltages like 120V, 240V, 480V. For example: 1 kVA = 8.33A at 120V, 4.17A at 240V, or 1.20A at 480V (3-phase). Charts provide quick reference without manual calculations.

100 amps to kVA?

100 amps equals 12 kVA at 120V, 24 kVA at 240V single-phase, or 83.1 kVA at 480V three-phase. The kVA calculation depends on your system voltage and configuration. Use the formula kVA = (Amps × Volts) ÷ 1,000 for single-phase systems.

kW to kVA calculator?

kVA = kW ÷ Power Factor. For unity power factor (1.0), kVA equals kW. Most systems have power factors between 0.8-0.95, making kVA higher than kW. Power factor represents the efficiency of electrical power usage in AC circuits.

VA to kVA?

kVA = VA ÷ 1,000. Simply divide volt-amps by 1,000 to convert to kilovolt-amps. This is the most straightforward electrical conversion since both units measure apparent power. For example, 5,000 VA equals 5 kVA, and 750 VA equals 0.75 kVA.

Generator kVA to amps conversion?

Generator Amps = (kVA × 1,000) ÷ (Volts × √3) for 3-phase or (kVA × 1,000) ÷ Volts for single-phase. Generator sizing requires matching kVA capacity to total electrical load. Consider starting currents for motors and other high-inrush loads.
