I’m running a film project that involve a huge Led wall. I have 1000 screens that can pull .6 amp each they are balanced for load on a 400amp 3 phase supply but I’m measuring the same current in the neural as the phases. Is this due to the harmonics it’s causing. If so should I worry about what it’s doing to the generator power it

Yes it's probably harmonic current, to be sure measure the frequency.

  • \$\begingroup\$ Thanks for getting back to me. I don’t believe they are PFC as they are a totally new product from China. When we have them all running I can it’s making the voltage on the generator a little unstable and I’m concerned that It will effect the windings on the generator. \$\endgroup\$
