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. The AC network includes the following ETAP modules:

ETAP Real-Time is a suite of software tools that offers a fully integrated enterprise solution. Through continuous monitoring, simulation, and optimization of electrical, process, manufacturing, and management systems that are in place, ETAP can maximize the entire production process, reduce losses, and increase profits.

ETAP Star device coordination is a new concept in performing steady-state and dynamic device coordination, selectivity protection, and testing. This is achieved by utilizing intelligent one-line diagrams, comprehensive device libraries, and an integrated three-dimensional database. Star is a fully integrated module within ETAP.

ETAP Automatic Relay Testing and Transient Simulator (ARTTS) system includes three high-precision test devices in one set. ARTTS can test a variety of protective relays including distance relays, as well as energy meters and transducers. ARTTS utilizes advanced hardware and software technologies for testing, simulating, and calibrating relays and comparing the actual test response with the manufacturer published data.

Developed for electrical designers and engineers, the Panel Systems module combines a graphical user interface and the intelligence of ETAP to easily design and analyze low voltage distribution systems. Coupled with exclusive features and advanced capabilities. Panel Systems is a quality tool you would only expect from the leader in power system analysis software.

Ground Grid Systems module enables engineers to quickly and accurately design and analyze ground protection. Advanced 3-D technology integrates with one-line diagrams, allowing engineers to visualize their ground systems and seamlessly utilize short circuit results. Flexible design methodologies allow for quick auto-designed layouts or very detailed schemes. Color-coded graphical plots provide impressive results.

User-Defined Dynamic Models (UDM) builds and compiles the control block diagrams used by the Transient Stability and Generator Start-Up modules of ETAP. UDM models can be used in multiple machines with independent settings within unlimited projects. UDM provides independent self-testing via load rejection, load acceptance, and terminal bus faults for validation of models and their dynamic behavior.

Cable Thermal Analysis helps engineers to design cable systems to operate to their maximum potential while providing secure and reliability operation. The advanced graphical interface allows for design of cable raceway systems to meet existing and future needs by using precise calculations to determine required cable sizes, their physical capabilities, and maximum derated ampacity. In addition, transient temperature analysis computes temperature profiles for cable currents, reducing the risk of damage to cable systems under emergency conditions.

Accurate prediction of cable pulling forces is essential for the proper design of cable systems. This knowledge makes it possible to avoid under-estimated and/or over-conservative design practices to achieve substantial capital savings during construction. The Cable Pulling module accounts for multiple cables of different sizes and allows complex 3-D pulling path geometry. A point-by-point calculation method is performed at every conduit bend and pull point. Both the forward and reverse pulling tensions are calculated for determining the preferred direction of pull.

ETAP seamlessly integrates the analysis of power and control circuits within one electrical analysis program. The Control System Diagram (CSD) simulates the sequence-of-operation of control devices such as solenoids, relays, controlled contacts, multi-sequence contacts, and actuators including inrush conditions.

The ETAP Data Exchange module (DataX) is used to import, export, and synchronize data between external data sources and ETAP. DataX transforms legacy data into ETAP, interfaces ETAP to external architecture such as GIS systems, AutoCAD, Microstation, or synchronizes ETAP with other applications. Customizable data mapping, intelligent error checking, and automated one-line diagram generator are amongst the many utilities with DataX.

ETAP GIS Map superimposes electrical one-line diagrams with the corresponding geographical maps of power generation, transmission, and distribution systems. Synchronize relevant electrical equipment information from GIS into ETAP and maintain the relationship between them. You can open unlimited views of GIS maps within ETAP, allowing you to manipulate GIS maps while working in ETAP. The analysis results are then displayed on geographical maps providing an effortless view of the power system states within GIS Map.
