Abstract: A computer-implemented system analyzes user-inputted hypothetical situations of an electrical distribution network design and automatically interprets, based on user input, a need to conduct analyses that improve reliability of the electrical distribution network. The computer-implemented system includes a storage device configured to store different configurations of the distribution network, data corresponding to elements of the distribution network, and a set of engineering analysis modules. The computer-implemented system includes a controller configured to display and use a graphical user interface (GUI) to prompt a user to answer one or more questions about the distribution network. The controller is configured to receive answers and data from the user and retrieve data corresponding to elements of the distribution network. Then, the controller automatically selects and runs one or more of the engineering analysis modules based on the received answers.

Abstract: A safety barrier comprising a support, a partition frame hingedly connected to the support, and a retractable membrane attached to one end of the partition frame. The partition frame and the support can be extended across an opening, such as a doorway, to securely position the barrier within the opening. The partition frame includes a first member hingedly connected to the support and a second member slidingly engaged to the first member. The retractable member may be deployed toward an opposite end of the partition frame to close off the opening.
