3. Electricity is the general term encompassing a variety
of phenomenon resulting from the presence and flow
of electric charge
The word originates from the Latin, meaning "amber-
like”, here amber (hardened plant resin) because
electrical effects were produced classically by rubbing
amber

5. ELECTRICITY GENERATION is the first process in the delivery of
electricity to consumers.
ELECTRICITY GENERATION is the process of generating electric
energy from other forms of energy.
British scientist Michael Faraday said that
electricity is generated by the movement of a
loop of wire, or disc of copper between the
poles of a magnet.
6. ELECTRICITY POWER TRANSMISSION is the bulk transfer of electrical
energy, from generating power plants to substations located near
population centers
Transfer of electrical power from Generating Stations to the
industrial, commercial or residential consumers is as important as
power generation.
Transmission lines, when interconnected with each other, become
high-voltage transmission networks. These are also known as
"power grids" or just "the grid".
7. ELECTRICITY DISTRIBUTION is the final stage in the delivery of
electricity to end users. A distribution system's network carries
electricity from the transmission system and delivers it to
consumers.
The network includes medium-voltage (less than 50 kV) power lines,
substations and pole-mounted transformers, low-voltage (less than
1 kV) distribution wiring
8. Major threats with
1.Open Street boxes
2.Open Street lamps
3.Open Live electrical cables
4.Absence of control boxes on street
lamps
5.Poor maintenance
6.Cables lying on the footpaths
7.Frequent expose to sun and rain can
lead to its wear and tear
8.Electricity easily accessibale leading to
electricity theft

10. The street boxes in campus of MSEDCL was maintained properly which is
ideal way of maintaining the street boxes
11. OUR VIEW
The interview conducted following views were generated regarding the maintenance practices adopted by the MSEDCL.
During our interaction we took a look at the complaint form which had various
common problems faced by the costumers listed one by one. But an option to complaint regarding
the poor electrical safety in public places was missing.
The Executive Engineer told us about the various safety gears the electricians use. However when we
asked the electricians to show these gears and tools, only the rubber gloves were shown. This raised a
question in our mind whether they are equipped with all such gears and tools.
The answer we got for locking of the street boxes shows negligence of the officials. Most of the street boxes were
found without locks. The doors of the street boxes were tied temporarily using ropes. Thus, there was much scope
for improvement in the practices adopted by the MSEDCL.

14. Safety can be defined as the control of
recognized hazards to achieve an acceptable
level of risk.
Safety precautions need to be taken at every
stage.
Should be documented in the form of Dos
and Don’ts.
Warning signs must be displayed.
15. Serious injuries, deaths, and property damage
occur daily.
Over 1000 electrical workers die each year
from workplace accidents.
97% of all electricians have been shocked or
injured on the job.
Electrocutions are the 4th leading cause of
traumatic occupational fatalities.
16. Electric field is invisible and silent.
Persons touching non-effectively
earthed, faulted metal parts in electrical
installations are exposed.
Persons working in substation, power
stations, transmission lines, cables etc are
exposed.
Persons who are unaware of presence of
electrical power.
17. Enforcement of safety rules and acts.
Electrical Safety Rules are to be made
mandatory.
Psychological approach Awareness of safety
is created.
Placing large signboards, displaying
drawings, DO’S and DON’TS.
E.g. Short circuits can be handled by
automatic protection system.
18. Handling of electric supply lines and
apparatus:
◦ Provided with tools and devices
such as gloves, rubber
shoes, safety
belts, ladders , earthing
devices, helmets.
◦ Every telecommunication line on supports carrying
a high or extra-high voltage line shall, for the
purpose of working thereon, be deemed to be a
high voltage line.
19. Street boxes:
◦ Street boxes shall not contain gas pipes, and
precautions shall be taken to prevent.
◦ All street boxes shall be regularly inspected for the
purpose of detecting the presence of gas.
◦ The owners of all street boxes or pillars containing
circuits or apparatus shall ensure that their covers
and doors are so provided that they can be opened
only by means of a key or a special appliance
