Network Analysis - Integrated AC & DC System
ETAP is a fully integrated AC and DC electrical power system analysis tool. Engineers use ETAP in thousands of companies worldwide in the design, analysis, maintenance, and operation of electrical power systems.

ETAP is developed under an established quality assurance program and is being used in the majority of high-impact nuclear facilities in the United States. From petrochemical and industrial applications to nuclear generation, ETAP is the power engineer's choice for system studies.

The ETAP Base Package includes the one-line diagram editor, which is one of the core tools used to perform power system studies. It is designed to enable engineers to quickly build and modify power system models and
test them with an array of analysis tools.

The Base Package includes vast collections of manufacturer and typical engineering data, which is built into well-organized, editable libraries. Several calculators are included within the Base Package to simplify the design and modification of electric power systems. The AC network includes the following ETAP modules:

 

 
DC network utilizes the same database as AC modules. DC Load Flow and DC Short-Circuit provide analysis capabilities for engineers to design and maintain DC power systems. Battery Discharge and Sizing Analysis is used to select the most appropriate battery banks, verify the maximum capability of existing batteries, and easily simulate a wide range of backup, control, and other DC scenarios. The DC network includes the following ETAP modules:
