Generator protective relaying is a critical concern throughout industry, whether it is for enormous steam turbines, smaller combined-cycle units, or even just smaller back-up generators. Due to the wide range of devices relays might be protecting, there are several broadly applicable protective elements that a relay technician can expect to see used to protect a generator. Additionally, a technician might find older electro-mechanical relays, static relays, or more modern microprocessor-based relays used to provide this protection, with each of these having unique challenges when testing.
This webinar aims to provide technicians and engineers working in the field with a high-level overview of common generator protection elements and will review the basics of the theory of the applications to explain why and what these elements are actually protecting the generator from. We will discuss generator differential, stator ground, field loss, and reverse power elements, amongst others, as well as testing techniques and practices for these elements. We will also cover the differences a relay technician should be aware of depending upon the type of relay being tested, whether it be electromechanical, static, or microprocessor-based. Finally, we will discuss the tools and methods a technician might use when testing and calibrating these different types of relays. The objective of the online seminar is for technicians to leave with not only new theoretical knowledge, but practical techniques they can use in the field.
This is a free webinar
All webinar attendees are eligible to receive 1 NETA CTD and 1 PDH or 0.1 CEU.
