An inductor is connected to a 480-volt circuit with a current flow of 125 amperes. What is the mini-mum kVAR rating for the inductor?
{kVAR }={\frac{{E}_{({\mathrm{inductive}})}\times{I}_{({\mathrm{inductive}})}}{1000}}
{kVAR }={\frac {480\times 125}{1000}}
kVAR = 60
Step-by-Step
The inductor in this example should have a minimum rating of 60 kVARs. An inductor with a rating less than 60 kVARs would probably be destroyed in a short period of time.
