S. Pangonilo
Welcome to the profile page of S. Pangonilo, PEE RPEQ.

I am a Professional Electrical Engineer (PEE) from the Philippines with extensive experience in electrical design,installation, start-up & commissioning, and maintenance in government & infrastructure, petrochemicals, bulk plants, refineries, ceramics, power and semiconductor plants.

Concept development, Front End Engineering and Design (FEED) and detail design particularly in hazardous area (Oil & Gas) electrical installation from Low Voltage to High Voltage applications are my experiences to list a few.

Professional Licenses

  • Professional Electrical Engineer  License No. 2574
    First Place, Professional Electrical Engineers Examination April 1991
  • Associate Electrical Engineer License No. 3057 April 1989
  • Assistant Electrical Engineer License No. 13301 October 1983
  • Registered Professional Engineer of Queensland (Australia)  - Registration No. 9607

Professional Memberships

Life Member No. 23633 - Institute of Integrated Electrical Engineers (Philippines)

Interests

  • Computers
    I tinker anything about computers - I am more interested on the old, unwanted junk
  • Web application development
    I like PHP best, javascript and AJAX. I once received an award from PHPClasses.org for my "Automatic Keyword Generator" script.
  • Linux
    I use Ubuntu as my file and web server.

I am a frustrated IT practitioner. As a consolation, I am just telling to myself, its fine, I am a fulfilled Electrical Engineer.

    Thanks for the compliments.

    Transformer impedance is defined in simple terms as the voltage impressed on the terminal of the transformer to produce a full load current on the opposite winding short-circuited divided by the full voltage rating of the winding.

    From the above relationship, the short circuit current Isc = Irated / Zpu but since MVA ? I, then MVAsc = MVArated/Zpu.

    On your second question, the equivalent MVA is actually the sum of the upstream MVA and the downstream MVA contributions.

    Hope this helps.

    Hi there, first off congrats on all your achievments.

    I'd like to know how you derive the MVAsc for transformers, [MVAsc = MVA/per unit impedance]and also how to derive the equivalent MVA for a given bus as shown in your MVA method tutorial.

    Hello po! Pardon me if this note isn’t a feedback to what you posted on top. This just seemed to be the easiest way of getting in touch with a kin. :) – josie
