ACHIEVEMENTS

Installation Project of HV 220 kV substation (ABU Zabad Substation):

Overseeing and preparing the site, ensuring safety and proper foundations and earthing system •
inspecting switchgear components for damage during transportation • performing pre-commissioning
procedures • assembling and mounting components according to guidelines and engineering drawings •
check interlocking and safety systems, complying with relevant standards • carry out insulation tests,
Electrical wiring checks, and commissioning • Ensure correct operation of protection relays, metering
devices, and control circuits • generate comprehensive documentation and commissioning reports •
Conduct final inspections and hand over the installed switchgear to the client or authorities.
Installation Project of (220/110/33 kV, 100 MVA) Power Transformer (MSH Substation): • Overseeing
and ensuring the site is well-prepared, including the foundations and grounding system • Inspecting the
transformer carefully after handling it • Lifting and positioning the transformer with expertise •
Assembling and mounting components like radiators, TR bushings, conservator tanks, transformer
breather, and mechanical protections with precision • Installing power connections on the HV/LV/TV
sides, grounding wires, and earthing transformer cables with accuracy • Vacuuming and filling the
transformer with oil diligently • Performing pre-commissioning procedures such as insulation resistance
test, dissipation factor test (Tan δ), transformer turns ratio test (TTR), polarity test, winding resistance
test, open/short circuit test, and Dyn OLTC scan with proficiency • Carrying out electrical wiring checks,
temperature meters calibration, and mechanical protection checks (oil/winding temperature relay test,
Buchholz relay test, pressure relief valve test) with confidence • Ensure correct operation of protection
relays • Commissioning and putting the transformer into service with full assurance.
