Power steering: fast power switchover keeps production lines running

摘要

As annoying as a power failure in your home can be, it is rarely dangerous or costly. Not so in industry. Production lines, especially the continuous lines in automotive or semiconductor manufacturing, papermaking, logistics and printing plants, are particularly vulnerable to unexpected power interruption. Here, serious damage can be caused to key production equipment, with economically disastrous results. To eliminate this risk, ABB developed the High Speed Transfer System, or HSTS. But the HSTS does more than assure an uninterrupted supply of power in the event of actual power failure; its unique ability to anticipate potential power interruptions and respond to voltage sags enables it to switch to an alternative power source in less than 1.5 cycles, providing the highest security for key production equipment.
