How many amps will a 37.5 KVA transformer carry?
It depends on the rated voltage of its secondary.
How many amps does a 55kva transformer can provide?
To determine the amperage a 55 kVA transformer can provide, you can use the formula: Amps = kVA × 1000 / Voltage. For example, at a standard voltage of 400V, a 55 kVA transformer can provide approximately 79 amps (55,000 / 400 = 137.5). The actual amperage will vary depending on the specific voltage used in the application.
How many amps on 25 kva transformer 1phase secondary 230 volts?
Take the KVA and divide it by the voltage. 25/.230 = 109 amps. The transformer can put out up to 50% more that its rated for short durations. So you could get around 150 amps out of a 25 Kva tranformer in a worst case situation.
Who many amps are needed to feed a 600 v to 480 v 3 phase 70 KVA transformer?
The equation for amperage when the kilowatts are known is Amps = kVA x 1000/1.73 x Volts.The electrical code states that a feeder for a transformer has to be rated at 125% for the primary and secondary load amperages.The amperage on the primary needed to supply a 70 KVA three phase transformer to its full capacity at 600 will be 68 amps. 68 x 125% = 85 amps. A #4 copper conductor with an insulation factor of 90 degrees C is rated at 95 amps.The amperage on the secondary needed to supply a 70 KVA three phase transformer to its full capacity at 480 will be 84 amps. 84 x 125% = 105 amps. A # 3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps.
How many output amps is a 45 kva transformer?
There is not enough information provided to answer. KVA is short for "Kilo Volt Amperes". That is, thousands of Volt Amps. In order to determine how many Amperes are flowing, you must know at what voltage it is operating. Amperes = 45,000 ÷ volts Bill Slugg
How many amps can you get from a 500Kva transformer?
The amps you can get from a 500 kVA transformer would depend on the voltage of the transformer's output. To calculate amperage, you can use the formula: Amps = Power (kVA) / Voltage. For example, if the output voltage is 480V, you would get approximately 1041 amps (500 kVA / 480V).
How many amps will a 250 kVA transformer in 220 volts secondary?
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
How many amps will a 37.5 KVA transformer carry?
It depends on the rated voltage of its secondary.
How many amps does a 55kva transformer can provide?
To determine the amperage a 55 kVA transformer can provide, you can use the formula: Amps = kVA × 1000 / Voltage. For example, at a standard voltage of 400V, a 55 kVA transformer can provide approximately 79 amps (55,000 / 400 = 137.5). The actual amperage will vary depending on the specific voltage used in the application.
What does a 350 kva transformer draw at 480 volt?
A 350 kVA transformer operating at 480 volts would draw approximately 416.67 amps of current. This is calculated using the formula: Current (I) = Power (kVA) × 1000 / Voltage (V). Thus, I = 350 kVA × 1000 / 480 V, which results in around 729.17 amps. However, it's important to note that this value assumes a power factor of 1; if the power factor is less than 1, the current draw would be higher.
Unanswered questions-how many amps for a 500KVA transformer.?
To determine the amps for a 500 kVA transformer, you can use the formula: Amps = kVA × 1000 / (Voltage). For example, at a standard voltage of 480V, the calculation would be 500,000 VA / 480V, which equals approximately 1041.67 amps. The specific current will vary based on the voltage level used with the transformer.
How many amps on 25 kva transformer 1phase secondary 230 volts?
Take the KVA and divide it by the voltage. 25/.230 = 109 amps. The transformer can put out up to 50% more that its rated for short durations. So you could get around 150 amps out of a 25 Kva tranformer in a worst case situation.
How many amps will a 10 kva transformer handle?
It depends on how many amps it was designed for. A 12.5kV/600v 10kVA 3 phase transformer can handle ~.5 amps on the primary and ~10A on the secondary. A 600/120V 10kVA 3 phase transformer can handle ~10A on the primary and ~50 on the secondary.
How many amps can a 0.50 kva transformer give 277v input 120v output?
To determine the output current in amps for a 0.50 kVA transformer with a 277V input and 120V output, you can use the formula: Power (kVA) = Voltage (V) × Current (A) / 1000. For the output at 120V, the current would be calculated as follows: 0.50 kVA = 120V × Current (A) / 1000, which gives Current = (0.50 × 1000) / 120 ≈ 4.17 amps. Thus, the transformer can provide approximately 4.17 amps at the 120V output.

Can you use a step up transformer 110220 with output of 16 kva?
Yes, but your input current is going to be high at 133 amps. The output of the transformer is not going to be 16 KVA, that is the rating of the transformer.
How many 120 volt 7 amp draw lights can be run on a 15 kva single phase transformer?
To determine how many 120-volt, 7-amp lights can be run on a 15 kVA transformer, first convert the transformer capacity to watts: 15 kVA equals 15,000 watts. Each light draws 120 volts * 7 amps = 840 watts. Dividing the transformer capacity by the wattage of each light gives 15,000 watts / 840 watts per light ≈ 17.86. Therefore, you can run a maximum of 17 lights on a 15 kVA transformer.
