How do you calculate current on delta to star transformer?
To calculate the current on a delta to star transformer, first identify the line current in the delta configuration (I_line). The phase current in the star (wye) configuration (I_phase) can be calculated using the formula: I_phase = I_line / √3. This relationship arises because the line current in a delta system is √3 times the phase current in a star system. Therefore, knowing the line current allows you to easily find the phase current in the star configuration.
How can you calculate the capacity in megawatts of a 400 kv power line?
To calculate the capacity in megawatts of a 400 kV power line, you need to consider the current carrying capacity of the line. This is typically based on factors such as conductor size, ambient temperature, and the type of insulation used. Once you have the current carrying capacity, you can use the formula P = V x I to calculate the power capacity in megawatts, where P is power in MW, V is voltage in kV (400 kV in this case), and I is current in amperes.
How you calculate voltage drops in a cable knowing resistance or impedance and line current in a 3phase system?
Ohm's Law - V = IR.
How you can calculate current of a load when you have three phase supply with 237 volts328.4 KW Power and 0.99 cosfi?
The general equation for power in a BALANCED three-phase load is as follows:P = EL IL x power factor...where EL and IL are the line voltage and line current, respectively.So all you have to do is to manipulate the equation to make the line current the subject, and insert your figures.
How do you calculate current and voltage passing through light globes?
To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.

How you join the next line with the current line in Vi editor?
If you go to the end of the current line and type J it will join the next line to the current.
How do you calculate 3 phase kWh from measuring the total phase current current?
In a balanced 3-phase system, if the three loads are star connected, the line current is equal to the load current. If the loads are delta connected, the line current is less than the load current by a factor of 1/sqrt(3).
What is phase current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line.
How do you calculate the total input current from a 3-phase power source when the current from each phase is known?
Add them upAnswerThere is no 'total' current in a three-phase system. The current flowing in each line (not 'phase') is considered separately. And you most definitely don't 'add them up'!
How do you calculate dg current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
How do you compute energy loss in transmission line?
Energy loss is I^2*R losses. Calculate the transmission line resistance, and multiply by the current squared per unit time (seconds if in watt/seconds, for example).
