respect to international codes and standards, quality, and integrity. We are committed and determined to
deliver innovative services and solutions that will assist our customers to accomplish their goals.”
MANAGING DIRECTOR: SYED FARUKH MAZHAR
3. Electrical Audit & Standard
“An electrical audit is completed at an industry or commercial building to determine its electrical efficiency.
Simply put, electrical efficiency means using less energy to do the same job. The audit will provide you with
complete electricity consumption and electrical efficiency assessment.”
Standard that we follow:
•IEC 61439, 60364-6 (Visual Inspection / Earthing)
•NFPA 70 E (Electrical Safety Audit)
•ASTM E 1934/37 (Thermography)
•BS-767 (Load Management)
•NETA/ANSI (Insulation Resistance Test)
•LIGHTING AUDIT (IESNA)
4. Visual Inspection”
“An electrical visual inspection is a survey of your electrical network. It is used to identify flaws, damage, or error in an electrical
installation like Electrical Panels, Power Cables, Earth systems, Circuit Breakers, and Switchgear.”
•F&M Private Limited conducted the Visual inspection of MD’S and SMD’S based on IEC 61439, 60364-6
Observations
•Panels don’t have clear identification markings. DB tagging requires
• Panels are not free of dust and debris. Maintenance required
• Without lugs & sleeves on cable
• Multi looping found at the circuit breaker.
•Earthing properly not provided.
Recommendations
The Main DBs of Plot # 131 & 132 need to rectify on an urgent basis
because these DBs were not in a good condition
5. “Earth Testing”
“Earthing audit conducted by F&M private limited ensures the good health of the complete Earthing system. It
is imperative that the Earthing system is inspected periodically to ensure efficiency.
Observations
• Proper earthing required for Panels.
• Several panels show “Open Line”.
• More than 5 ohms resistance of earth found on various DB’S.
•Total of 37 DBs, 18 DBs were not lying in an acceptable range
•Recommendations.
Need to rectify this earthing issue as early as possible.
6. “Thermography”
Thermography is the process of using an infrared camera to look for abnormally hot or cold areas on a
component operating under normal conditions. It is a viable nondestructive evaluation technique and is the
simplest of all thermal inspection techniques.
Observations
• Several DB’s have overloaded circuits & equipment.
• Electrical Fire can erupt due to looseness or overload of circuit
•Recommendation
DB lies in the EXTREME & Moderate category
It t is requires to shift the load on particular DB’s in order to
lower the temperature in a safe zone.
7. “Electrical Drawings” (SLD)
“Electrical Drawings are built internationally & widely used to check the Quality of Electrical systems & for
Troubleshooting as per International Standards. Electrical System Studies are done to find out system deficiencies
& loopholes in existing networks via specific studies.”
• Observations
• DB’S has design flows in distribution network.
•SMDB’S Should follow the IEC standard for proper designing of
Cable, breaker, Neutral for each load and earthing.
•Recommendation
Number of DB’s requires to change its MCCB in order to avoid
Short Circuit and protect the distribution network.
8. “Load Management”
“Load management program is necessary to balance the three-phase load. We measure the load on each phase
and then balance it.”
•Observations
•The distribution network of Bills Inc has unbalanced three
Phase load.
Need to shift the load in order to avoid burning and short
Circuit of cable.
Recommendation.
……… MDB’s has unbalanced load and need to shift the load.
10. Conclusion
At this conclude we try to put our hard work in this project and completed successfully. Although there’s
few difficulties for performing tasks, which are impossible without co-ordination of client, this project
enables us to study about existing system and also make our selves clear about the capability and
specifications of system, at the end we mark some of points for system sustainability.
