Hello Electricians,
This is my first post and I'm glad to be one of this forum member.
However, to clarify my question. I've a "Skin Effect Heating System", fed by 1240 V. The circuit is quit simple, Phase U, Neutral in the middle and Phase V. Phase U and Neutral feeding the heating cable#1 (Length 2100 m), and Phase V and Neutral feeding the heating cable#2 (Length 2100 m). I'm facing a small problem, the amp meter for Phase U shown 234 A and Phase V shown 236 A. Nothing affected everything is normal the 87T relay (Unbalance current relay) didn't operate and the system working well. Now my question is, why do I've Amps difference knowing that the both phases fed by one voltage source? Is it because the heating cable maybe aren't the same length accurate?
Thank U
