Substation Apparatus Maintenance Program:


This 24-hour practical course provides you with methods and procedures used internationally. Predictive, periodic or condition based (on line diagnostics and monitoring) maintenance are basic methodologies in substation maintenance. The course is for a beginner, or an experienced maintenance technical staff who wants to be effective as a test engineer, and for an advanced test engineer to learn new concepts in power transformer testing, oil recycling or oil filtering concept, and basic results interpretation. The course will also focus on issues related to causes of bushing breakdown, arresters, oil, impedance, leakage reactance and most of all short circuits rating a transformer can withstand.

Please note the course content does not include DGA (dissolved gas analysis) completely. The unpredictability of operation lies in the way substation assets are maintained and this technical training and participants will be guided on how to become a substation maintenance engineer improve his knowledge based on international standards.

TESDA Accredited Training Program:

Course Background:

The EPIRA law mandates reliability, efficiency, and practically zero downtime in substation apparatus operation. Technical services group, power system maintenance team and facilities maintenance engineers are the front liners in ensuring the asset longevity operation and recovery of investments.
