How Line Reactor eliminate Nuisance Tripping
Transients due to switching on the utility line and harmonics from the drive system can cause intermittent tripping of circuit breakers. Furthermore, modern switchgear, equipped with solid-state trip sensing devices, is designed to react to peak current rather than RMS current. As switching transients can peak over 1000 volts on a 600 volt system, the resulting over-voltage will cause undesirable interruptions.
A reactor added to your circuit restricts the surge current by utilizing its inductive characteristics and mitigates nuisance tripping. The impedance of a transformer will have similar effects.
