A1: There are no exact evidence of the acute illnesses caused by exposure to electrical substations, but adverse chronic effects were recorded like baldness of the hair and cancers to the extreme cases. Since electrical systems emits high radioactive materials, then there are effects to the growing cancers cells in our body which by then eventually will mitigate and turn these cells to produce cancer related illnesses.
A2: The above is a common misconception. EMF fields weaken at a rate of distance away from it squared. This means at 100 meters from a substation, you are receiving 1/10,000th of the EMF that you would receive at 1 meter. Realistically speaking, you are likely to get much more EMF on a day to day basis from the wiring in your walls, your cell phone, and any wireless equipment you have at home (phones, networks, sound systems, etc.) than you would from a substation or nearby overhead power line, simply because you will be much closer to these than you are to that power line or substation.
To my knowledge there have been no concrete studies done proving a link between substations and overhead power lines with cancer, "acute illnesses", or any chronic illnesses. Substations tend to give off noise, which you might find annoying. Other than that, you're safe being outside the substation fence.
to chek working or repairing eqipments in substations or industris
It's the engineering concerning protection, control, supervision and communication of electrical substations or power plants.
channel the electrical energy supply form other substations to that area
At substations, the voltage of electricity is either stepped up or stepped down depending on its application. They serve as an intermediate point between the power generation plants and the consumers' electrical distribution system. Substations also provide various protection and control mechanisms to ensure the reliable and efficient transmission and distribution of electricity.
There are 230kv and 110kv GIS substations in chennai functioning from 1998 ,commssioned by Tamilnadu electricity board.
all the these
The resistance of the cables that conduct the electric current away from the substations causes the cables to dissipate some of the electrical energy in the form of heat.
What do truck-mounted infrared cameras look for in substations and on power lines
Most illnesses were cancer related because of the ionising radiation in the nuclear fall-out after the explosion.
Rather than where? Circuit breakers are always located in substations.
gas insulated substations are installed especially where floor area available is limited and maintenance cost is more
