Someone told me the other day that Power Factor Correction is only used for single phase power sources like welding power sources. Is this a fact?

It is not true as power factor can be corrected either single phase or three phase. But it is dependent on the factor that why you want to correct the PF. If there is any penalty from energy supplier for poor power factor then you have to correct the PF, single or three phase.

Hello ssbn727
Welcome to the forum.
Power factor correction can be applied to any inductive load connected to the AC supply, however power factor correction is typically only applied to installations where there is a power factor penalty or KVA maximum demand tariff as there is little or no advantage to the end user unless they have their own source of supply.
Power factor penalties and KVA maximum demand charges are typically only applied to larger industrial installations. I have never come across them being applied to domestic or small industrial installations, so the major usage is on three phase,not single phase applications.
Best regards,

ssbn727,
some high-power fast PFC are able to compensate single-phase loads, for example arc welders, also for power of megawatts.
Not all 3-phase compensators are in position to compensate single-phase loads.

Mario
