Sir,

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.

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.

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

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!
