Ungrounded system: Application examples

Where to use a floating system?

The need for a continuous power supply is constantly increasing – in hospitals, on ships, in manufacturing plants, process plants, data centers, control rooms, airports, railway systems, transport systems, heating systems, cooling systems, etc. In tunnels and below ground, lighting and ventilation must work faultlessly; submarine crews as well as astronauts in space equally depend on a reliable power supply.

IT systems with ground-fault monitoring represent the ideal technical solution in these cases. For this reason, floating systems are used in particularly critical applications like control circuits, medical locations or mobile power generators. However, by now they can also be found in newer applications, such as electric vehicles, photovoltaic systems or industrial plants with variable-speed drives.

In combination with innovative ground-fault monitoring technology, the IT system contributes to protecting people and installations against the hazards of electrical current by eliminating critical system and operating conditions or by detecting and signalling them at an early stage. Besides the increased safety, this helps to minimize maintenance and downtime costs. In addition, operators are able to evaluate system data according to their requirements and use it to improve the condition of the installation. Due to the various economic and technical advantages, an ungrounded system with high-performance ground-fault monitoring is almost always profitable in rather complex installations.
