Efficiently Build and Evaluate System Models

Using the advanced power flow analysis, you can create and evaluate your electrical system models efficiently and effectively, providing you with accurate results. Built-in functions such as the automatic device evaluation, alarms for critical and marginal limits, a powerful results report comparison analyzer, and intelligent, user-friendly graphics make it the most reliable load flow analysis software.

ETAP load flow software provides results including comprehensive bus voltages, power factors for each branch, directional currents flows, and voltage drop calculations throughout each electrical system model. ETAP allows for multiple grid connections, detailed generator modeling, solar turbines, and induction generators for radial and mesh networks. ETAP interactively utilizes multiple calculation methods in order to calculate the best possible results.
