SDH Series CT

What are the errors in C.T?

There are two types of errors occures in CT. These errors are:

1.Ratio error:- The ratio error is the amount by which secondary current differs from the exact proportionality of the          primary current of CT. It is expressed in percentage of rated secondary current.
2.Phase difference error:- The phase difference error is the angle by which the secondary current differs in phase from the primary current of CT. It is expressed in minutes of arc.

SDH range of current transformers can be applied to test,control,display and record the running of the electrical equipment,

and to protect the equipment against the damage,in the AC circuit with the rated voltage value below 720V and the
frequency of 50-60Hz.The product can be also applied to form a complete set of mine transformer
