The conventional short-circuit calculation is a robust calculation algorithm that does not follow any particular standard. It offers:
The IEC-60909 short-circuit calculation adheres to the international IEC-60909 guidelines and supports fault current calculations for three-phase radial or meshed AC networks.
Calculates short-circuit levels on three-phase radial AC electrical installations of ships and mobile and fixed offshore units. It calculates both AC and DC components of the current from fault inception to steady-state for three-phase symmetrical short-circuit condition.
The ANSI short-circuit calculations adhere to the North American ANSI C37.5, ANSI C37.010, and ANSI C37.13 standards relevant to short-circuit studies of specific duty types.
The Series fault analysis evaluates the effect of open circuits or asymmetrical line impedance conditions on the network, which usually causes a significant increase in the neutral current.
The Simultaneous fault analysis studies the impact of having faults at different locations simultaneously on the network.
The Fault Locator analysis takes the short-circuit recorded from a current measuring instrument to determine possible locations of the fault on the network.
The Network Fault option, integrated in the standard short-circuit analysis, performs a series of short-circuit analysis in batch mode and offers the possibility to generate detailed reports and summary reports on the entire network or at user-defined monitored locations.
The Voltage sag analysis assesses the impact of a sudden reduction of voltage magnitude caused by network faults, or other disturbances such as motor starting or overloads.
The Equipment rating verification analysis evaluates devices to determine if they are properly sized to perform their intended functions as the stress on them increases along with the growing energy demand.
