IT system: Unearthed systems for maximum availability

Of what importance is the system type to the installation?

Nowadays, technical installations in all industries are characterised by ever-increasing complexity and automation. From highly developed production lines to robot technology, the amount of equipment that requires a reliable power supply to function smoothly is steadily growing. Therefore, the foundations for reliability and availability of an installation are already laid by selecting the right power supply system. Along with personnel and fire protection, fail safety is the key factor when choosing an appropriate power supply. During the planning phase of an installation, three system types are available: the TN system, the TT system and the IT system.
