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.

Myth About SF6 Gas In Electrical Equipment· This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203) For sealed for life MV equipment a range below 0,1 % per year is common.
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
