    I am so glad to note that you have expanded your teaching to such an extent that now you have various levels, focusing on special technology, to keep up to date with the advancement. I am also happy to note the sparkle on the faces of those who complete each course under you, which is evidence by itself as to how much they enjoyed learning! A good work that cannot be rewarded equally! Congratulations to all and wish them all the very best!

      Hi Parasuraman,
      They are from the MRT Maintenance department that deals with the door 48Vdc board repair. This class was specially prepared for them only and they brought along their PCBs to ask for advice. I gave my best to them to make sure they have lots of repair ideas to tackle the board problems.

        Great to know, dear! I wish all the very best from the botom of my heart and pray to God to give you health, wealth, happiness and long life! As mentioned by me earlier, teaching is something that cannot ever be repaid abundantly! Lucky are the students who get a chance to get classes from you, a veteran in the field and ready to impart the full knowledge!

            I am also involved in advance level Repairing & Maintenance activity of Inverters of solar & UPS system. But some times I need technical help for
            repair. Is there any asking question & Answer on line interaction media type system so that I will solve the problem in remote / Isolated location of Solar Sites?
            Please guide me for the same.

    Very good job done by all participants from the MRT Maintenance department who deal with 48Vdc board repair! I don't know if MRT here means MASS rapid transit but 48VDC is the standard in communications facilities serving up both wired and wireless services. And if it really is used in rapid train transit for subway, underground railway or metro it means that it is very safe because anything operating at or below 50V DC is generally accepted by safety regulations and electrical code to be a safe low-voltage circuit.
    Unlike our Dutch railways that use 1500 volt dc or more. Our high speed south railway and the Betuweroute even use 25000 volt dv at a frequency of 50Hz. Best of luck to all MRT maintenance engineers!

      Hi Albert,
      Yes, MRT is Mass Rapid Transit. Thanks for your sharing and comment!

        PS: Of course the mentioned 25K Volts is HighVoltage at 50Hz AC and it will in the near future replace all our old 1500V DC trains. In Germany they use 15KV AC at the moment which means that at present all trains need multiple electrical powering engines that can switch between those voltages. Which also means that the old 1500V DC trains can't use those trajects anymore.
