Accuracy Limit Factor | Protection Class CTs | What is Current Transformer? | What is 5P10 5P20? |
In this video, you will be able to understand about Protection class CTs like, 5P10/5P20 in very brief & crisp. Explanation given is very simple & short. A little detail is also given about Accuracy Limit Factor, Composite Error etc. with suitable examples.
Content:
5P20 means:
"CT can sustain up to 20 times the rated current value… Its core will not saturate up to this value of fault current & Maximum composite error would be 5 % at this time."
Example:
A 300/1 ratio 5P20 class CT’s core… will not get saturated for fault current up to 20*300 = 6000 A & the max composite error at this fault current would be 5 %.
