Motor Acceleration
ETAP's advanced Motor Acceleration module enables engineers to thoroughly evaluate load changes to electric power systems. Motor Acceleration is fully capable, whether you want to start one motor or transition your entire power system to a different state. Sequence-start a series of machines using static or dynamic models, operate Motor Operated Valves (MOVs), and simulate the switching actions of Load Tap Changers. Plotting and time varying graphical display enable engineers to quickly evaluate results and make decisions.
