What are the electrical hazards in the EFU House?
Which equipment’s are doing the electrically work proper or they have to be replaced or
repaired.
What are the requirements for electrical improvements, tools and which tests perform?

10. Quality and inspection
HT and Transformers:
High Voltage side has been spotted and HT panel side is operating in proper
condition, 1000KVA transformer is in normal operating condition but other one 1500KVA
transformer is leakage the oil (fig-1) which can be dangerous overtime, the dehydration
of transformer took place two years ago in 4, Nov2017, but in usually according to
electrical standard the transformer dehydration should be in 2~3years.
Figure-1 transformer oil leakage
LT, ATS and PFI Panel:
Low voltage panel board operating in proper working condition, only
tagging is not present on the breaker but this will be resolved in two to three working
days. Auto-transfer-switch is normal in working condition but a component phase failure
relay (fig-2) which is not in proper working so it must be changed as soon as possible ,the
Initial Report
power factor improvement panel was not doing in right condition due to power factor
relay parameter values was incorrect, they’ve been right and now functioning properly.
Figure-2 Phase failure relay
Distribution Board Floor to Floor:
On each floor six distribution boards are present for different operating
function the details are given below.
1- AC-DB which is used for air conditioner and chillier,
2- SMDB which is used for others dBs power control.
3- Normal DB which is used for lights on main supply.
4- Emergency DB which is used for lights on main and gen both.
5- Power DB which is used for power sockets only.
6- Common DB which is used for lobby lights.
In the distribution boards MCC-breakers are present in good condition and work in
proper way but MC-breakers (fig-3) working condition are very dangerous. DB for
submersible motors (fig-4) its wiring and breakers are about to change.

Total no off breakers MCCB & MCB which is present in each distribution board
the detail of only 8th floor is given below.

Earthing and grounding:
The earthing and grounding is the main safety function regarding to
electrical equipment and human safety so I performed the earthing test in the house and
whose results (fig-5) are satisfied and we will be perform this test every three month, so
results are given below.

Initial Report
Figure-5 Earth test result.
Trench and Cable Tray System:
Overall cable tray system is present in healthy condition but for the
cable satisfaction a test is performed by insulation or magger meter which is not available
in the electrical components so should be provided to us as soon as possible because we
can do our test quickly and proper way.
Fire alarm and smoke detector system:
The fire alarm system has a minor problem so I trace the problem
and solve it now the system work in proper condition and other one smoke detector is in
right working condition.
Electrical and Mechanical drawings:
There are no electrical and mechanical drawings are present in the
department so if possible then provide me drawings by admin or manufacturing company
else I will make it by using the CAD but take a lot of time and very important for
electrical fault tracing.
Electrical Toolkit:
In electrical toolkit almost the equipment’s are present but a few tools
that we need to take e.g. digital clamp meter, safety gloves and shoes. Also we required
some store material like 50-no electric tube rod and stater, 15-no power sockets, shroud,
power and control thimbles, power and control wire, round able pipe, insulator, neutral &
earth links. But I do more to improvement it like I made a sheet for issue and return detail
mention in the sheet because most boys are forgotten the tools in the panels.
Initial Report
Inspection and Quality Control:
For the improvement of quality it’s mandatory for inspector/authorized
person to have a cycle within a month and we tried to fix the minor mistakes. As an
electrical supervisor I try to bring this department into quality condition, with all my
experience and hard work. I made an inspection sheet (Fig-6) for the improvement of
department condition.
Note*-Underline mean we demand these things.
I hope the above will suffice for your consideration but should you need any further information,
Please contact me.
Yours truly,
( Sadam Hussain)
