Current Transformers (CT)

Current Transformers (CT)

Through my practical experience (19 years) in the field of electrical power substations, in addition to obtaining a master’s degree in engineering sciences in electrical power and machines engineering. This course was prepared using the best engineering programs that link the academic, theoretical aspect with practical reality through practical experience in electrical power substations, with high and extra-high voltages. In addition to practical experience in the field of distribution networks on medium and low voltages.

This unique method of explanation and course preparation was thought out to suit all technical levels, starting from students of engineering universities and various technical institutes and even specialized engineers with high experience in the field of electrical power systems and electrical substations, especially the specialization of protection engineering and measuring devices.

The course was explained in a practical way that depends on the simplicity of theoretical speech and the greater interest in images from the practical sites that we can link the academic, theoretical study with what actually exists in the practical sites of the actual application after passing this course.

My course is closely related to electrical protection and measurement systems. My course explains the most important part of how measuring and protective devices work in the electrical power system.

The course was explained in a simplified way from the beginning of the introduction of current transformers and the reason for thinking about its manufacture until training on how to choose current transformers that fit measuring and protective devices with practical calculations.

In this course, I will talk about:

* Introduction and the importance of Current Transformers (CT).

* Practical explanation of Current Transformers (CT).

* Components of Current Transformers (CT)

* Technical specifications of Current Transformers (CT).

* Nameplates of Current Transformers (CT).

* Different symbols of Current Transformers (CT).

* Different types of Current Transformers (CT).

* Connections of measuring and protective devices with Current Transformers (CT).

* Difference between the secondary current (1A) and (5A) of Current Transformers (CT).

* Saturation problems of Current Transformers (CT).

* Opening the secondary winding circuit of Current Transformers (CT).

* Tests of Current Transformers (CT), like:

01 Winding Resistance Test of Current Transformers (CT).

02 Insulation Test of Current Transformers (CT).

03 Polarity Test of Current Transformers (CT).

04 Turns Ratio Test of Current Transformers (CT).

05 Saturation Test of Current Transformers (CT).

* Practical Example: How to choose the suitable Current Transformers (CT) for measuring or protective devices.

* Protective devices that are connected with Current Transformers (CT).

* Measuring devices that are connected with Current Transformers (CT).

* Critical site problems of Current Transformers (CT)
