Why Use Line Inductors?
Shock absorbers are a necessity on a rocky, bumpy road for your vehicle’s longevity and safe ride. Likewise, an electrical shock absorber (3 phase inductor) can increase the reliability of electronics equipment on 3 phase A.C. lines having noise, line spikes, surges, hard lines, black outs or brown outs etc. Switching capacitor banks by utility companies can cause high voltage power spikes which can damage electronics on motor drives. Also, induction heating furnaces, electrical smelting, electrical arc welding, close proximity to generators and power mains can all destroy variable speed drives under certain conditions. Arcing from single shoe or roller bar collectors on electrification systems can cause a gradual breakdown of input diode bridges on variable speed drives. With 3 phase inductors, it is possible to absorb many of these destructive processes in a simple an inexpensive manner. Inductors are small, light and less expensive than alternative protection methods like 100% trans
