Question For Jr. Engineer Electrical
Hii I am preparing for the exam of Jr, engineer electrical , can you provide me some important question related with this exam or provide me the previous year question paper ? Here I am providing you paper of the Jr. Engineer Electrical in the attached file . Here are some of the content of the file. In ring main distribution systems, the distributor is fed (1) By one feeder (2) By two feeders (3) At different points (4) By four feeders 2 Spot pricing is about (1) Power factor improvement (2) kVA demand reduction (3) Tariff/ rate at different times (4) Generation cost reduction For the complete paper please download the attached file. ![]() ![]() ![]() ![]() Last edited by Neelurk; March 6th, 2020 at 01:49 PM. |
