Final answer:
The capacity of an Integrated Drive Generator (IDG) typically ranges between 40 to 90 kVA, depending on the aircraft. The question provided, however, addresses the power transmission line instead of an IDG. For the transmission line, the power supplied can be calculated by multiplying the voltage by the current, equating to 120,000 kVA.
Step-by-step explanation:
The student is asking about the capacity of an Integrated Drive Generator (IDG), which is used in aircraft to convert mechanical energy from the engine into electrical energy for onboard systems. However, the provided information relates to a power transmission line, not directly to the capabilities of an IDG. The question seems to be incomplete or possibly misstated as it pertains to a different subject matter. Typically, the capacity of an IDG in an aircraft can range between 40 to 90 kVA (kilo-volt-amperes), depending on the aircraft model and the design of the IDG system.
For the power transmission line described, to find the power in kilo-volt-amperes (kVA) supplied by the transmission line, you would use the formula for apparent power in an AC system, which is Voltage (V) × Current (I). In this case, 240 kV × 500 A = 120,000 kVA or 120 MVA (mega-volt-amperes).
