5p10
5% of error when there is 10 times of current in the
circuit.

Answer / ravi kaslikar

5P10 means 5% composite Error up to 10 times of rated CT
current. 10 is for ALF ie Accuracy Limit factor. P
indicates Protection class CT.

Answer / gopalsing

5P10,Means 5%(5P) Of Ration Error Even if 10 Times fo Rated
current pass through the primary of CT

Answer / arun kumar

10 times of rated primary current injected means 5 percent of composite error is created .
5 - composite error .
P- protection.
10- accuracy limiting factor

these r the standard ALF list - 5 , 10 , 15 ,20 ,30
composite error is related to harmonics

Answer / grayghostgg

5p10means 5 percentage error and 10 mean ten times the
secondary current the CT can withstand

Answer / bhanu

One of our gas turbine generator unit "1st stage rotor ground fault" alarm was occured several times. we tried to measure some voltage vulue ground fault protection relay (UNS3020a made by ABB and we measured the value of: Ground: 0.9VDC 5V: 5.8VDC 24V: 23VDC u+: 300 – 350mVAC Rf1: 17.5mVAC Rf2: 17.6mVAC The unit still running and the alarm was reset. As of 6pm yesterday and unitl now no alarm happened again. I our protection relay was defective?
