Considerations for Integrating Protective Relays into VFD-Driven Motors
Variable frequency drives (VFDs) – also known as adjustable speed drives (ASD) - provide significant advantages such as reduced starting currents and adjustable speed control for the operation of induction/synchronous motors, but present additional challenges around process control and efficiency. Protection relays provide additional functionality and monitoring to ASD-driven motors such as enhanced current protection (differential) and monitoring of electrical, mechanical, and thermal motor aspects.
Join GE expert JC Theron for a live webinar and Q&A session on the considerations for integrating protective relays into a VFD-driven motor, part of our ongoing series of Tech Talks to refresh your knowledge on key protection and control fundamentals.
In this session, learn about:
Types of ASD systems, and their benefits and applications
Protection zones in ASD systems, with protection recommendations and unique considerations for each
Additional electrical and mechanical functions that can be added on ASD-driven motors by means of electrical signature analysis, allowing real-time motor condition monitoring
