This webinar, by analyzing the protection against indirect contact in ac (50/60-Hz) low-voltage power systems by automatic disconnection of supply, seeks to clarify both the terminologies and each type of grounding system adopted in IEC standards, with the intent to create a common reference for practicing engineers in the matter of bonding and earthing of power systems.
This presentation will discuss how the recently updated ETAP unbalanced load flow feature has been used for analyzing the effects of an open-phase fault on several TVA nuclear power stations.
This lessons learned paper provides the fundamentals and guidelines for modeling thermal overload curves in engineering software.
Revisiting ILS benefits at PT Newmont after a decade in service.
ETAP makes the creation of multiple configurations and operating modes for the system being modeled easy once the model has been created and then the available incident energy for each bus in each configuration can be determined and compared. The worst case incident energy and corresponding personal protective equipment (PPE) can be put on arc flash labels to be applied to the equipment.
Study case with two distant floating units interconnected with a subsea cable and fed by gas turbine generators. ETAP software has been used for motor starting analysis. A discussion about the choice of motor and generator models is developed and the comparison between calculation methods is presented. A particular focus is made on motor starting methods when direct on line is not possible, including soft starter simulation and VSD representation.
This presentation discusses the modeling of two large fossil fuel generating stations in Texas. One station was constructed with UFER grounds, zinc ground rods, and insulated conductors for connecting the zinc ground rods. Different techniques employed for successful solutions within the existing capabilities of the ETAP grounding module and interpretation of results will be presented.
This presentation will describe some of the Rumaila Oil Field gathering methods, calculations, limitations, relay protection reviews, and future plans of the ROF electrical distribution system. The ROF ETAP electrical model will support a safe, reliable, documented, and analyzed electrical distribution system and expanded to arc-flash calculations and the ETAP Real-Time.
This presentation will showcase KOC Electrical Information Manager System (EIMS). The main objective of EIMS is to automate the process of reserving power supplies and updating by interfacing between GIS and ETAP programs in all KOC Assets.
An in depth discussion Microgrids can deliver enhanced reliability, energy and cost-efficiency, as well as environmental benefits. This discussion will walk you through the key drivers for "why a microgrid", "what types of microgrids there are" and "how a microgrid is developed"
