Application

Four sets of settings are available to optimize the IED operation for different system
conditions. By creating and switching between fine-tuned setting sets, either from the
LHMI or configurable binary inputs, results in a highly adaptable IED that can cope
with a variety of system scenarios.
Different conditions in networks with different voltage levels require highly adaptable
protection and control units to best provide for dependability, security and selectivity
requirements. Protection units operate with a higher degree of availability, especially,
if the setting values of their parameters are continuously optimized according to the
conditions in the power system.
Operational departments can plan for different operating conditions in the primary
equipment. The protection engineer can prepare the necessary optimized and pre-
tested settings in advance for different protection functions. Four different groups of
setting parameters are available in the IED. Any of them can be activated through the
different programmable binary inputs by external or internal control signals.
