Get Medium Voltage Current Transformer LMZBJ1-10/325( )

The 5P20 can be explained as below: P = Protection Class. 5 = Accuracy Number in percentage. It means the maximum permissible error will be 5% 20 = Accuracy limit factor indicates that the CT will sense the current with the specified accuracy even with 20 times of its secondary current flows in the secondary.

the accuracy of PS class is not defined. generally used for unit protections differentials…. And a 5P20 CT means it will give a +_5% error when it reads 20 times the rated current …which means when a fault happens more than the CT ratting upto 20 times it can measure with a 5% errors with plus minus…

For 33 kv Transformers for Single Breaker Controlling two transfo. mers up to 2 x 5 MVA, the CT ratio shall be 200/100/5/5/5 A.

what is 5p10 in ct 5P10 means the maximum permissible limit of error (accuracy limit) is 5% at 10 times rated current (Accuracy Limit Factor). CT will give ratio error of only 5% even if fault current reaches 10 times the nominal value (In), after that CT will start to saturate.

CT's for protection must have suitable accuracy for fault currents. They are characterized by their accuracy class (generally 5P) and the accuracy limit factor FLP. A protection CT is designed to send as reliable an image as possible of the fault current (overload or short circuit).

The CM-CT 50/1 is a plug-in current transformer from the CM-CT range. The current transformer has a rated primary current of 50 A and a secondary rated current of 1 A.

what is 5p10 in ct 5P10 means the maximum permissible limit of error (accuracy limit) is 5% at 10 times rated current (Accuracy Limit Factor). CT will give ratio error of only 5% even if fault current reaches 10 times the nominal value (In), after that CT will start to saturate.

For example, 5P10 transformer accuracy limit factor is 10. This means than current transformer will measure with less than 5% error, when primary current is not bigger than 10 times the rated nominal current.

CT's for protection must have suitable accuracy for fault currents. They are characterized by their accuracy class (generally 5P) and the accuracy limit factor FLP. A protection CT is designed to send as reliable an image as possible of the fault current (overload or short circuit).

The class designation is an approximate measure of the CT's accuracy. For an example; the ratio error of a Class 1 CT is 1% at rated current. The ratio error of Class 0.5 CT is 0.5% or less.

The CM-CT 50/1 is a plug-in current transformer from the CM-CT range. The current transformer has a rated primary current of 50 A and a secondary rated current of 1 A.

Its notrecommended not to evaluate which one is better, as both are giving less than 5% of error while measurement, 5P10 gets saturated over and above 10times of rated current where as other one at 20times. Its application which differetiate the use of 5P10 and 5P20.

For example, 5P10 transformer accuracy limit factor is 10. This means than current transformer will measure with less than 5% error, when primary current is not bigger than 10 times the rated nominal current.

The class designation is an approximate measure of the CT's accuracy. For an example; the ratio error of a Class 1 CT is 1% at rated current. The ratio error of Class 0.5 CT is 0.5% or less.

Precision of protective current transformer: 10P10, 10P20, 5P10, 5P20, etc. Meaning of precision: Take 10P10 as an example, that is, when the current flowing through the current transformer is less than 10 times its rated current, the error of inductor is less than (+10%)

Its notrecommended not to evaluate which one is better, as both are giving less than 5% of error while measurement, 5P10 gets saturated over and above 10times of rated current where as other one at 20times. Its application which differetiate the use of 5P10 and 5P20.

In current transformer 5P10 means when 10 times current flows in primary then there is 5% error occur in secondary. 5 denotes ratio error. P denotes class of protection.
