Explain the Term in CT Name Plate – Class: 5P10..

Answer / chr

5P10 DETERMINES 5% ERROR IN MEASURING DATA FOR 10 TIMES THE
CURRENT FLOW IN THE CT.

Is This Answer Correct ?    37 Yes 3 No

Explain the Term in CT Name Plate – Class: 5P10..

Answer / r. r. patange

In 5P10, P stands for protection, there are two main
classification of current transformer
1) Metering CT
2) Protection CT
so above mention CT can be use for protection purpose.

the first digit (5) stands composite error.
composite error - it nothing but the differance between
instanteneous RMS valuve of primary current and secondory
current, multiply by transformer ratio.

the last digit (10) is stand for the times of primary
current. It means this protection CT can capable of
measuring current of 10 times than its rated during fault
condition with error of 5% and without getting saturated.

Explain the Term in CT Name Plate – Class: 5P10..

Answer / barkha thakur

P indicates the protection level & 5 indicates the accuracy
it means when sec current is increased by 10 times, ct
senses the current with 5 % error

Explain the Term in CT Name Plate – Class: 5P10..

Answer / sangram

first i explain the term:- 5 is a class of accuracy, p you
should use for protection purpose, 10 you should load up to
10VA.
you should use this CT for protection purpose, and the
burden rating should 10volt Amp at 100% load pass in
primary, you should allow +/-5% error for this CT.

Explain the Term in CT Name Plate – Class: 5P10..

Answer / wasim maniyar

For example, CT is specified as 15VA, 5P10 where 15VA denotes burden, 5 denotes composite error and 10 denotes ALF(Accuracy Limit Factor).

Is This Answer Correct ?    2 Yes 0 No

Explain the Term in CT Name Plate – Class: 5P10..

Answer / faheem

according to my study the there are two type of accuracy
class 5p & 10p 5p=+-1 % error,and 10p=+-3% error.and last 10
shows the accuracy limit factor 5,10,15,20 and 30.. It means
this protection CT can capable of
measuring current of 10 times more than its rated during fault
condition with error of +-1% and without getting saturated.
