What is the current in 1KVA Transformer?
Tis question is incompleet.1000 va =1 kva.This is the power capacity of transformer. A transformer having 2 currents Primary current and secondary current . for that we required both voltage. Simply we can calculate by a formula Voltage x Current x 0.8(power factor)=1000.
How do you calculate primary current?
If it's a step up or step down transformer and you know the secondary side current, multiply the secondary current by the turns ratio. If you know the power in the secondary winding but not the current, divide the secondary power by the secondary voltage to get the secondary current and then multiply the secondary current by the turns ratio to get the primary current. The turns ratio is the number of turns on the secondary winding divided by the number of turns on the primary winding. For a step up transformer, the turns ratio will be greater then one. If it's a step down transformer, then the turns ratio will be less than one. If you don't know the turns ratio, divide the secondary voltage by the primary voltage to get the turns ratio.
WHAT TYPE OF transformers has secondary current of the same order as the magnetising current?
A one to one, i.e. isolation, transformer.CommentIt might be worth pointing out that the secondary current is determined by the load, and the primary current is then determined by the secondary current. The questioner appears to think that the secondary current is determined by the primary current.
In a transformer what induces a current in the secondary coil?
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
How do you calculate turns ratio for current transformer?
The turns ratio is the number of primary turns divided by the number of secondary turns. This is the same ratio as input current to output current. ie the turns ratio N = I1/I2
How do calculate secondary current of step down transformer?
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
How do you calculate in CT ratio?
The CT (Current Transformer) ratio is calculated by dividing the primary current (the current flowing through the primary circuit) by the secondary current (the current flowing through the secondary circuit). The formula is CT Ratio = Primary Current (Ip) / Secondary Current (Is). For example, if a CT is designed to handle 100 A on the primary side and outputs 5 A on the secondary side, the CT ratio would be 100 A / 5 A = 20:1. This means that for every 20 A flowing in the primary circuit, 1 A will flow in the secondary circuit.
How do you calculate the current of the secondary side of the transformer without a load are impedance known?
Without a load the secondary current is zero, by definition.
How do you calculate primary curuent?
Current is calculated on the load. If your question on transformer primary current, then use the formula N1I1=N2I2, where N1 and N2 are primary and secondary coil turns and I1 and I2 are current in respective coils. This is very basic simple formula. You have reframe your question more specifically.
Formula for relation between primary winding and secondary winding?
The turns ratio of Primary / Secondary tells you have the voltage and current will be changed. The secondary current will be (primary turns/secondary turns) times the primary current, and the secondary voltage will be (secondary turns / primary turns) times the primary voltage.CommentThe above answer is a little misleading, because the secondary current is determined by the load, and not by the transformer's ratio. It would, therefore, be more accurate to say that the primary current would be equal to the secondary current times the (primary turns/secondary turns) -i.e. not the other way around!
What is formula for calculate maximum current?
volts divided by resistance equals maximum amperage (current)
How do you calculate MVA rating of power transformer?
The product of the secondary rated current and the secondary rated voltage will give you the rated V.A of the transformer.
What is the formula to calculate Conduction current in a coaxial cable?
Jc=sigma.E

How should I calculate this. A single phase transformer is rated at 99kVA The primary voltage is 6.6kV and the secondary voltage is 220V Assume no losses and calculate The full load primary current?
First find the ratio of the transformer. 6600/220 volts. Second find the secondary current, I = W/E, 99000/220. Third divide the secondary current by the transformer ratio. The answer will be the primary current. To check your answer (W (or VA) = V x A) multiply the primary current times the primary voltage and the secondary current times the secondary voltage and they should both equal the transformer's kVA.
How do you calculate current?
to fine I (current) when you have R (resistance) and V (voltage) you use the formula: I = V / R
What is the formula to calculate the percentage of weight loss?
The formula to calculate the percentage of weight loss is: (Initial weight - Current weight) / Initial weight x 100.
