Voltage transients in MV power systems have been observed to contribute to failures of both power and instrument transformers in data centers in recent years. This white paper provides a background regarding the nature of the transient problems, as well as a discussion of factors that may put transformers at risk. Several common solutions are available to help safeguard transformers, and each of these is discussed along with some of the pros/cons of each solution type.
Switching transients and surge protection for MV transformers in data centers
This paper will provide an introduction to switching transients that may result in excessive transformer intra-winding stress.
