Course Overview
Power system equipment are meant for normal operation wherein the voltages and currents should be within the tolerable limits. However due to multiple reasons its likely there can be abnormalities in the power system. Hence it’s not only necessary to design equipment to withstand the thermal stresses due to any abnormalities such as faults but also isolation of the equipment thereby protecting the equipment and simultaneously operation of the healthy equipment of the power system.
ETAP is one the most widely trusted and used power system analysis software used for verifying the suitability of the power distribution system and its components, recognizing coordination related disruptions and outages, and gathering the required data to perform a detailed study.
The purpose of this Power system Studies training course is to learn power system modelling and analysis using ETAP software for verification, stimulation and optimization of power system design. In this course, the ETAP software will be looked at in order to assess different power analysis models.
Proper modelling of power system equipment and the correct fault analysis of electrical networks are prerequisites to ensure proper identification of power networks. Sustainable design, fit-for purpose design including optimized design are some important factors that is required by Power system engineers to maximize the use of existing assets, and hence, the use of accurate modelling and analysis of power system equipment are of paramount importance.
This power system studies training course will empower you with thorough knowledge in a range of ETAP functionalities used to solve practical power system problems such as equipment sizing in steady-state and short circuit conditions, motor acceleration scenarios, protection of the equipment, selectivity, device coordination, and the effects of harmonics on the power system.
