Harmonics and Renewable Power Plants - Modeling, Analysis, and Mitigation

Solar photovoltaics (PV) power plants are playing a greater role in the generation of power in North America, and several factors expect this increased growth in the coming years. As PV generation is modular, some facilities range from 5 -20 MW and interconnect with a utility’s distribution circuit. Larger facilities can provide 300 MW or more, are often designed with their own collector substation, and interconnect with transmission level voltages. This discussion, given by David Lewis, PE, Grounding and Power Systems at EasyPower, will step through several modeling methods to accurately assess the grounding system performance with regard to IEEE Std 80 personnel safety criteria. Transferred voltages, lumped impedances, regional analysis, and other analysis concerns will be addressed.

Are Short Circuit and Coordination Studies Required by OSHA?

OSHA electrical safety system requirements can sometimes be misunderstood by safety professionals and even some compliance officers. General Industry standard 1910.303(b)(5) requires that short circuit analysis is done to design and installed equipment is correctly rated and coordinated. But beyond that, it should also be updated periodically for continued compliance. In this webinar, given by Lee Marchessault of Workplace Safety Solutions Inc, we discuss how arc flash study software can help with compliance and ensure equipment is properly rated and coordinated. We will discuss OSHA requirements related to short circuit and coordination studies, and describe fault current, what causes it, and how you can determine system conditions. We also discuss compliance and mitigation of over-dutied equipment and uncoordinated systems. Finally, we explain how arc flash hazards are directly related to short circuit analysis.

Arc Flash Hazard Report & Calculation Values Explained: Arcing Current, Arcing Fault Time, and More!

The release of IEEE 1584-2018 necessitated significant changes in the calculation method for arc flash incident energy, in some cases adding complex new steps to the process. Some of these changes are reflected in the way arcing current is calculated and the way arcing fault time is determined. While this is all done behind the scenes in EasyPower, it is still important to understand the basics of these calculations and the most important values, so that you can have confidence in your short circuit, coordination, and arc-flash study results and recommendations. In this Refresher webinar, Jim Chastain at EasyPower shows how EasyPower has implemented the updated IEEE 1584-2018 equations and where you find answers in the EasyPower ShortCircuit module.

Enhance MV Transformer Arc Flash Safety

With the growing demand for safety in the grid, the need for arc flash energy reduction has never been higher. There are many methods to accomplish the reduction of arc flash energy but typically require separate pieces of equipment that adds complexity during installation. This webinar, given by Kyle Zemanovic, an Application Engineer at Eaton, reviews how the Arc-Reduction VFI (AR-VFI) Transformer reduces incident energy in downstream arc flash zones and mitigates the danger posed by power distribution equipment.

EasyPower Label Editor & Designer – Advanced Use & Applications

EasyPower continually strives to improve the features of our tools based on user requests and feedback. Our custom label editor and designer enables our users to have control over every detail of their labels and has continually improved over the years based on user feedback and requests. In this refresher webinar, Jim Chastain at EasyPower shows the basics of how our custom label editor can be used – and also dives into some key features including: The ability to assign PPE values based on company policy which may differ from consensus standard guidelines The ability to add a custom PPE boundary based on a custom PPE rating Translation to languages other than English.

Lightning Protection and Earthing for Wind Turbines

Lightning protection and earthing for wind turbines is an essential part of ensuring generation of electricity and avoid unplanned downtime. IEC 61400-24 focuses specifically on lightning protection for wind turbines and guides the reader on how to perform lightning risk analysis, informs them on what to look for from turbine manufacturers, and instructs them on how to plan for maintenance. In this webinar, Ivan Grobbelaar, Pr.Eng at DEHN South Africa, showcases methods for calculating lightning related risk on wind turbines, incorporating correction and environmental factors such as lightning ground strike-point density, turbine height, mountainous terrain, and winter lightning. He then presents the calculated risks and determines the required lightning protection measures to be verified with the turbine manufacturer. Focus is drawn to lightning limits of commercially used turbine blades and how to ensure that blades are not catastrophically damaged, avoiding unplanned maintenance and down time.
