Power quality and system availability and reliability maximized by using high-speed transfer systems

More and more power utilities and industrial markets are putting the focus onto the importance of power quality and uninterrupted power supply. The permanent availability of electricity is vital for a great number of processes. The interruption of critical processes due to power outages, voltage sags or interruptions can result in lost productivity, damaged production equipment and products, delays in delivery, costs for cleaning and restart and in worst case to injury to people and pollution of environment. Problems of poor power supply can be solved by using high-speed transfer systems: Modern-day switchgear in power plants and industry usually provide at least two independent supplies, a main and a stand-by feeder. High-speed transfer systems (HSTS) guarantee continuous, uninterrupted supply by ensuring that if the main feeder is deliberately switched off or if a malfunction puts it out of action, supply is automatically switched over to the intact stand-by network as quickly as possible
