Current limiting functions
● Limiting the reactor current to the rated and/or maximum current
For operation without overload profiles, the reactor current is limited to the rated device
current.
For operation with overload profiles, the reactor current is limited to the maximum current
of the overload profile.
For more detailed information, see Chapter "Dynamic overload capability (Page 329)".
●
Limiting the power to the rated power in the standard voltage range
This limit is active if the voltage at side 1 or side 2 is greater than the rated voltage
(600 V) of the device.
