special for eee students: project on advanced monitoring ... the load study conducted in Kollam city, we can see that, the present load is 43MVA and the load rises by about 6% annually. Moreover the number of power interruptions can be reduced to a great extent if we set up a G.I.S substation in Kollam city. With the existing system voltage drop is also very high which can be minimized if the proposed system is set up.
