Your fellow electrical engineer Jesús Pérez Díaz is back with a great new article featuring a video tutorial (ETAP software). Enjoy!

LV MOTOR PROTECTIVE DEVICE

250 hp WEG motor / HMCP Cuttler Hammer / Overload Relay Schneider Electric

Hello everyone! In this article I want to show you how to determine the protective device settings of a typical and simple protection scheme usually applied to low voltage motors, considering the electrical protection basis and using ETAP (Electrical Transient and Analysis Program)to build the time-current curve.

The Need

As technological advancements have been made, we are now able to design our experiments in a better manner. One such advancement is the usage of simulation in the case we can’t conduct the practical experiment. Furthermore, it serves as a good feasibility assessment tool. The cost of prototyping and development of certain complex systems is costly. The role of simulation is to mimic the experiment in a virtual model. All major functions and actions are defined through algorithms and mathematical values. In this manner, it is possible to predict the outcomes of a complex experiment via a computer based simulation model. So as the systems increase in size & complexity the need for computer simulations becomes necessity to work efficiently & effectively.

The purpose of writing this post is to introduce Professional Engineers/students with different software that are available for Power System Analysis (PSA). All of the software’s listed below have some unique features that make them different from the other.

Now let’s take a look at some simulation softwares and their usage.

ETAP

Softwares for Power System Analysis 1

Used primarily for power system simulation, the main attributes of this software are:

  • Real time data management
  • Model design for electrical power systems
  • Customizable features

It has a great diversity of users from power consultants to high level designers. The most common software that ETAP offers is ETAP Power Management Software which is developed keeping the needs of the Engineers under consideration. This software aids in better, smart & flexible designs.
