Power Factor Overcorrection Risk

Recommended Posts

I'm installing static capacitors to correct power factor at the supply, base on our calculations we need a 25KVAr, but we have a 15KVAr and a 50KVAr 480V both, if I install the 15KVAr I will get a reasonable PF correction, but if I add the 50KVAr I will overcorrect. But what are the risk of doing this overcorrection?
