1.Ensure power supply available.save energy by disconnecting
2.ensure all electrical machines should be earthed ,because
in construction mostly related with steel structures,if any
leakage from machine then persons will get shock.
3.if work is going on outside protect machine by covering
that from rain fall.
4. make awareness to all people how to switch off power in
case of any electrical accident.
As an engineer our responbilities on site is make sure that
the electrical installation should be as per IS code or
National code as applicable according to authority,proper
designing of system,maintenance view,feature extention etc.
in the construction field the roll of electrical engineer is
1-he has to see the basic design engineering of the project
2-detail engineering with safety factor in the design .
3-basic & detail engineering for provision of earthing pits
of electrical intallation.
4-design for illumination of different area and lux calculation.
5-cable size calculation cable scheduling &its route
selection ,over head or under ground
6-proper protection system for all electrical installation .
7-design for fire alarm &detection system &so many more
which i am not writing here
The main role of electrical engineers in construction
projects is to supervise the electricians in handling all
the electrical works considering the safety and quality
requirements. The electrical engineer in the construction
site also reads and studies the electrical plans (usually
done by electrical design engineers) and implement it in
the site and sometimes do necessary actions whether to
correct or to improve the design. They coordinate with
other electrical engineers in the implementation of the
electrical system design and also with other engineers of
different fields, such as civil and mechanical engineers,
to make the construction job easier.
1)The main roll of Electrical Engineer in Construction
field is fully about safety,power consuming ideas and
limiting the wastage of power supply.
2)Creativity in designing new circuits which is capable of
the building design.
3)Reducing the Power consumption day by day.
Top-performing electrical site engineers have good communication skills in addition to time management and complex problem-solving abilities, according to O*Net OnLine. To perform the necessary tasks, they might use laboratory evaporators, signal generators, semi-conductor process systems, spectrometers and computer-aided design software, such as Finite Element Method.
How can you calculate in detail the VA burden of current
transformer used for Restricted earth fault protection?
Please understand that the CT required here is Class PX or
X. Also please show the calculations for knee point vtg,
stabilizing resistor, magnetising current.
For these 2 devices what their power ratings are ?
1) single phase : AC 220V & starting amps 3Amps (i.e.
starting torque) and the stabilized amps 2A ... For deep
2) single phase : AC 220V & starting amps 2.7Amps (i.e.
including the starting torque of a CRT monitor) and the
stabilized amps 1 Amps
