Description

Dear All,Welcome to the course about "Mastering Medium Voltage schematics". This training is start from very basic level to advance level. Focus has been given to deliver the practical and hands on knowledge.Trainer have over 18 years of field experience and has worked at 11/132/220/500kV Substation, 1263MW power plant, 660kV HVDC system.  worked with several companies, SIEMENS, ABB, GE, SEC, KE, WAPDA, NTDC, ARAMCO, SABIC, MARAFIQ. Trainer has given hundreds of trainings online and offline, so it will be great to join this training and take advantage of field experience. This online course is part 02 of the Mastering Medium Voltage Switchgear drawings.  In this part we have covered the following topics.* Introduction to motor charging circuit * Spring mechanism operation* Spring charging interlock circuit* Spring charge indication* Task to identify mistake in drawing* Local, remote, emergency & off controls* Test & service position and interlocks* Contact multiplication relay* Closing circuit matrix*  What is slamming and antislam circuit *Coil save circuit for tripping and closing coil* Coordination of trip command duration* Seal in or latching circuit* What is pumping action in MV switchgear* Pumping due to SOTF* Pumping due to open and close command at same time* Anti pumping relay circuit* Adding spring contact in closing circuit* How mechanical interlocks are presented in drawings* CB trolley test & service position interlock in closing circuit*Tripping latch interlock in closing circuit.Thanks
