محول التيار أو ال current transformer . CTIslam Hesham
محولات التيار من اهم العناصر المستخدمة فى معظم مجالات الهندسة الكهربية فنجدها فى محطات الجهد العالى و المتوسط و ايضا نجدها فى دوائر التحكم و لوحات الجهد المنخفض
كما ان محول التيار له استخدام هام قد يغفل عنه البعض و هو clamp meter او ما يعرف بالكلامب امبير
يعمل محول التيار لانتاج تيار كهربى صغير على ملفات الثانوى secondary بينما يمر تيار كبير فى الابتدائى
This PPT explains about the circuit breaker, and its types. Then about the need and purpose of the circuit breaker. And finally the testing and types of testing of circuit breakers.

This Presentation is about l.v switch gear design, presented during the graduation project final discussion 15/7/2018.
It presented a good summary of switch gear components and types and practicing on AL.HAMOOL W.T.P M.D.B design using SIEMENS SIVACON S8
The apparatus used for switching, controlling & protecting the electrical circuits & equipments are known as switchgear.
The switchgear equipments is essentially used with switching & interrupting currents either under normal or abnormal operating condition.
It consists of devices such as switches, fuses, circuit breakers, relays etc.
Basically every electric circuit needs a switching device & a protecting device.
Protection of transmission lines (distance)Rohini Haridas
This gives idea about necessity of protection of transmission line and protection based on time grading as well as on current grading. Also includes three step distance protection of transmission line
Automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary. The balance can be judged by measuring the system frequency; if it is increasing, more power is being generated than used, which causes all the machines in the system to accelerate. If the system frequency is decreasing, more load is on the system than the instantaneous generation can provide, which causes all generators to slow down.
he main purpose of transient stability studies is to determineThe main purpose of transient stability studies is to determine
whether a system will remain in synchronism following major
disturbances such as transmission system faults, sudden load
changes, loss of generating units, or line switching.
