Limit the impact of the fault within the installation
In the event of a fault, the voltage of the installation is severely affected and risks causing a loss of loads. In particular, the management of faults related to short circuits within a critical installation using static transfer systems (STS) is particularly important.
To guarantee the continuity of the supply to their load, the STS must:
- Operate autonomously
- Be able to detect and differentiate a short-circuit downstream or upstream
- Carry out a transfer of sources without overlap to avoid the propagation of the fault
- Ensure the islanding of a short-circuited load
In the event of a short-circuit downstream of an STS, it must isolate the fault to prevent its propagation and alert the operator. The other STS connected to the same source must protect its load by immediately transferring it to an alternative source without propagating the fault.
STATYS Integrable Static Transfer Power Unit
The STATYS Integrable is a fully integrated Static Transfer Power Unit for integration into a cabinet or a power distribution unit (PDU).
Supplied by two independent sources, STATYS Integrable increases the overall electrical infrastructure availability during abnormal events and programmed maintenance.
