Hey,
Needed some help with relay coordination
I have a system whose arc flash study i have already conducted. However, the arc flash level is very high. I have now been assigned the task of reducing the arcing time by coordinating the devices again. I have read IEEE 242 chapter 15 on...
Why are both the maximum and minimum short circuit currents required for relay co-ordination? Isn't the maximum short circuit current sufficient? And while computing minimum short circuit current, do we neglect only the motor contribution or are there other parameters to be ignored?
I came across the concept of sensors, plugs and frames used in switchgear in the United states. I haven't been able to fully grasp the need and working of the above. Until now, i've only heard of current transformers used for wiring relays and metering. Could someone explain and give me some...
