Increase Load on Welding System and Disturbance Caused


Thread Starter


I want to increase a load of 300KVA on my system, basically welding machines. How can i make sure i'll not disturb the system on normal operation, or that the influence of harmonics generated will not create problems on the system?

Do you guys have any reference for this kind of calculation?

what makes you think that the loads you are adding will increase your harmonics?

what makes you think increased harmonics will harm your system in some way?

if you do end up with harmonics causing problems with your system, about all you can really do is hire an engineer who solves these kind of problems for a living to take a look and make suggestions on where to spend your money to reduce the problem.

the thing is there are all kinds of systems that do not care much about harmonics, others that are more sensitive to them.
