Understanding How Transformer Size & Impedance Affect Equipment Short Circuit Ratings
The serving transformer plays a significant role in the available short circuit capacity of an exposed energized circuit part in any location on an electrical distribution or control system. This webinar, given by Greg Harstine at CES Inc, focuses on how transformers of various sized impact the available short circuit capacity at a particular location. The focus is on common electrical distribution systems found in small to medium size industries and also looking at the system connected to an infinite bus compared to an example utility system given the available system short circuit capacity and X/R ratio.
