What is the total current in a 14,400 volt overhead circuit with a power rating of 300 Kva and a real power load of 240 Kw?

To find the total current in a circuit when given the voltage and power ratings, we can use the relationship between power, voltage, and current. The formula that connects these variables is:

[ P = V \times I ]

Where:

• ( P ) is the power in watts (or volt-amperes for apparent power),

• ( V ) is the voltage in volts,

• ( I ) is the current in amperes.

In this case, we have a power rating of 300 KVA, which is equal to 300,000 VA. However, the real power load is provided as 240 kW, corresponding to 240,000 watts. Since we are interested in the total current based on the real power load, we would use the real power for our calculation.

First, we'll convert the voltage into a usable format:

[ V = 14,400 \text{ volts} ]

Now, using the formula for current, we rearrange it to calculate ( I ):

[ I = \frac{P}{V} ]

Plugging in the values:

[ I = \frac{240,000 \text{ watts}}{14,400 \text{ volts}} ]

Now
