Join GE’s next Tech Talk on integrating relays into VFD-driven motors




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
