Line choke calculation
NettetThe two main reasons of line voltage drop are-. Voltage drop in line due to inductive reactance- It is almost 10 times higher than the general line resistance voltage drop. Voltage drop caused by high line resistance- It is nominal as compared to the inductive reactance voltage drop. Read more on….

Need a choke for a 1000 volt supply, but they are too expensive, use a lower voltage choke and put in the negative side of the supply so it sees a low voltage to ground. Beyond this use as much inductance as your wallet and physical constraints will allow.
