Transformer Inrush Current: Stop Nuisance Trips with Harmonic Block

Master transformer inrush physics and eliminate nuisance trips in medium-voltage systems. Learn why energization creates 8-15× current spikes, how second-harmonic content distinguishes inrush from faults, and five protection strategies that reduce trips by 85-95%.
