CT error 5P10 It means .10 times of current fiows as per Ct
ratio the error will be 5%.

Answer / mriganka das

Class 0f CT : 5P10.....

It state that if there 10 times current of plug setting
flows through the primary, there would be +/- 5 % error may
take place in the secondary side of the CT.

So 5 is the tolarence or accuracy class & 10 is the
accuracy class limit factor.it is denoted by the symbol
Eeta.

Answer / s c budhiraja

this relates to ct meant for protection purpose.5p stands
for class of ct which means the current error at rated
primary current is 1%(+or-)and 10 mean that this ct will be
reasonably accurate upto 10 times the rated primary current.

Answer / pravin

15 VA 5P 10
accuracy limit factor = 10
accuracy class = 5P
accuracy power = 15 VA

Answer / sasi karthick a

It defines tat, at 10 times (During fault condition) of the
rated current of CT the accuracy shall be +/-5%.

for more, plz refer is-2705 part-1 to 4, ETD-34.

Answer / ganesan.n

5P - Accuracy Class

10 - Composite error rate accuracy limit primary current (%)

on 22.03.2015 at 17:15hrs Y phase 66kV class Power Trf-2 Current transformer has flashed over and oil came out. The failed CT has been replaced on 24.03.2015 at 13:15hrs and the Trf has been charged in presence of RT Hassan after conducting the pre-commissioning tests. On the same day at 17:00hrs the commissioned CT has again flashed over and immediately the Trf  has been isolated from power supply. It is confirmed the secondary is not opened and checked the earth integrity and is found ok. Here what would be the reason for the CT failure?
