  1. 208.2 Amperes
    Three Phase Example: Using a 75 KVA Three Phase Transformer as a starting point. 75 KVA is equal to 75,000 VA. (K= 1,000) The full value in VA, 75,000 divided by 1.732 = 43,302, which is then divided by the Voltage 208V = 208.2 Amperes. This is a "Three Step Division", technique: VA / 1.732 / Voltage = Amperage.

    How are Transformers sized?
    Transformers are sized by determining the total load required (in amps). Transformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating.

    How to calculate transformer kVA rating?
    The transformer kVA rating can be used to calculate amps. Also see explanation of kVA to Amps formulas here Single-phase Transformer Amps = Transformer kVA rating * 1000/E Three-phase Transformer Amps = Transformer kVA rating * 1000 / (E*1.73) Find the amperage rating of a transformer having 225 kVA and 500 V in case of single and three phase

    How do you calculate KVA in a 3 phase transformer?
    Three Phase Transformer Full-Load Current (Amps) = kVA × 1000 / (1.732 × V) Where: kVA = transformer rating (kilovolt-amperes), V = voltage (volts). Turns Ratio = N 1 / N 2 = V 1 / V 2 = I 2 / I 1 Where: N1 = number of turns on the primary, N2 = number of turns on the secondary, V1 = primary voltage, V2 = secondary voltage, I1 = primary current,

    How do you calculate a 50 kva transformer?
    Example: A 50 kVA single-phase transformer has a 4000 V primary, and a 400 V secondary. Assuming an ideal transformer, determine (a) the primary and secondary full-load currents, (b) the transformer turns ratio. a) V 1 = 4000 V, V 2 = 400 V, Transformer Rating = 50 kVA = V 1 × I 1 = V 2 × I 2

    How do you calculate primary voltage in a transformer?
    V(primary) = Primary Voltage in Volts V(secondary) = Secondary Voltage in Volts Transformer turns ratio, V(primary) * I(Primary) = V(secondary) * I(secondary) The primary voltage is equal to the product of the secondary voltage and primary current divided by secondary current.

    How do you calculate transformer capacity?
    Transformer capacity is rated in KVA (kilo-volt-amperes). The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating. When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed.
