Substation capacitor banks: (mark all that apply)
A capacitor will raise the voltage upstream of the bank.
Reactive power is due largely to which of the following:
If a feeder has 1000 kvar of load, what would be the optimal size of each cap bank if two capacitors are applied at optimal locations?
Voltage drop due to a large resistive heating load can be reduced by switching in a capacitor bank.
Line losses due to a large resistive heating load can be reduced by adding a capacitor bank.
Is an 80 K fuse link an acceptable application on 900-kvar bank on a 12.5-kV system.
Which options can minimize the likelihood of nuisance fuse operations on capacitor cutouts? Mark all that apply.
What is the voltage rise after adding a 3-phase, 3-Mvar capacitor bank (12.5 kV, 3-phase short circuit at the point = 2 kA, X/R=4)?
Consider a 12.5-kV express circuit that is four miles long with 350-kcmil AAC construction with Z_{1} = 0.0557 + j 0.1242 ohms/kfeet. Find the amount of capacitance in kvar needed to have zero voltage drop.
For a 1200-kvar capacitor bank on a 12.5-kV distribution circuit, calculate the I^{2}t for peak outrush into a nearby fault where the resistance between the capacitor and the fault is 0.02 ohms. Find V_{pu} needed to for the I^{2}t to exceed that necessary to blow a 30T fuse.
Using the IEEE 8500-node test case in OpenDSS, find the losses for each of the following cases. Solve the system at peak load.
