What is the formula of single-phase?

Standard Electrical Formulas Used for Power Consumption Calculations

TO DETERMINE:	SINGLE-PHASE	THREE-PHASE
KVA	I x E 1000	I x E x 1.73 1000
Kilowatts	I x E x PF 1000	I x E x 1.73 x PF 1000
Horsepower	I x E x ïF x PF 746	I x E x 1.732 x ïF x PF 746
Amperes (when HP is known)	HP x 746 E x ïF x PF	HP x 746 1.73 x E x ïF x PF

What is the formula of phase voltage?

Phase voltage, on the other hand, is the potential difference between one phase (R, Y or B) and neutral junction point, denoted by V phase = VR (voltage in red phase) = VY (voltage in yellow phase) = VB (voltage in blue phase).

How do you calculate current per phase?

The solution is to calculate the VA = E x I transposed to I = VA / E to get total amps. Then compute I per (conductor or leg) using the rule that on a three phase system current on an individual conductor is 1/(3^0.5) = 1/1.73 of the total current.

What is single phase voltage in India?

In India the standard residential Single Phase Electricity supply voltage is 220 V ( AC ) at 50 Hz Frequency.

How do I Calculate voltage?

Ohms Law is used extensively in electronics formulas and calculations so it is “very important to understand and accurately remember these formulas”.

1. To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
2. To find the Current, ( I )
3. To find the Resistance, ( R )
4. To find the Power (P)

How do you calculate kVA in single phase?

Calculation with line to line voltage

1. S(kVA) = √3 × I(A) × VL-L(V) / 1000.
2. So kilovolt-amps are equal to √3 times amps times volts divided by 1000.
3. kilovolt-amps = √3 × amps × volts / 1000.
4. kVA = √3 × A ⋅ V / 1000.
5. S = √3 × 12A × 190V / 1000 = 3.949kVA.

How do you calculate kW in single phase?

kW = PF × A × V / 1000 In this formula, the amount of power (in kW) is equal to the power factor of the load (PF) multiplied by the phase current measured in Amps (A), times the RMS voltage (V), and divided by 1000.
