SAMI UL Haq

* Directed full-cycle O&M of Water Treatment Plants (WTP) and Sewage Treatment Plants (STP) under National Water Company (NWC) project contracts, ensuring 99%+ plant availability.
* Programmed, configured, and troubleshot Siemens S7-300/400 and Allen-Bradley (Rockwell) PLCs for automated dosing, filtration, and pumping sequences.
* Managed WinCC SCADA platform developed HMI screens, set up alarm management, and implemented real-time trending to support plant operators.
* Performed preventive and corrective maintenance on centrifugal pumps, submersible pumps, motor control centers (MCCs), VFDs, and 11kV/0.4kV transformers.
* Calibrated and maintained field instrumentation includes flow meters (electromagnetic, ultrasonic), pressure transmitters, level sensors, and analytical instruments (pH, chlorine, turbidity).
* Led Loop testing, cable termination, and commissioning activities during plant expansion phases; liaised with project engineers on FAT/SAT documentation.
* Reduced unplanned downtime by implementing structured PM schedules and root-cause analysis protocols for recurring electrical faults

▸ Operated and maintained an 18 MW run-of-river hydroelectric generation facility, including
generators, excitation systems, 11kV busbars, and protection relays.
▸ Performed scheduled and emergency maintenance on synchronous generators, HV/LV
switchgear, and distribution transformers.
▸ Diagnosed and resolved electrical faults in control panels, protective relay schemes
(overcurrent, differential, earth fault), and SCADA-linked RTUs.
▸ Maintained and tested battery backup systems, UPS units, and DC control power supplies critical
to plant protection.
▸ Supported annual major overhauls and outage planning, coordinating with mechanical and civil
teams to achieve zero lost-time incidents.

* Assisted senior engineers in daily electrical inspections, panel maintenance, and recording operating parameters.
* Gained foundational experience in power plant protection systems, single-line diagrams, and electrical testing procedures.
