Commissioning, Testing, and Maintenance of Electrical Systems (1.2 CEUs)
Thursday, March 21, 2013
Friday, March 22, 2013
Participants in this course will be offered comprehensive and crucial guidelines to understanding elements and procedures involved in the commissioning and start up of electrical apparatus and systems involved in major industrial and commercial projects. The course addresses the special problems that may be encountered in the starting up of any electrical system for the first time, which, regardless of size, type or industry, is a special event. Fundamental to the commissioning task is the significant effort required to test each individual apparatus to ensure its proper functioning and its ability to offer service continuity under the specific operating conditions required by the industrial environment. A good deal of time will be spent discussing practical aspects of testing major equipment such as cables, motors, transformers and switchgear.The course will highlight testing procedures, standard testing frequencies, what to expect in the results of testing and remedial actions. The importance of maintenance is to achieve the design life expectancy; it cannot be overemphasized and the course will offer details of philosophies underlying maintenance practices. This course deals with safety considerations and testing and start-up procedures for all the components of any electrical system. The course will provide useful guidelines on what to do when things go wrong during this phase of a project.
To provide a comprehensive understanding of principles of accomplishing a successful commissioning and start up including testing and subsequent maintenance of the electrical system.
- Maintenance managers and power system consultants.
- Electrical professionals who need to refresh and expand their knowledge on electrical systems.
A basic understanding of electrical system operations is needed, but participant do not necessarily have to be experts in the areas covered. In addition, professionals who are starting their career in the field of power in electrical utilities, industrial or commercial and institutional facilities will benefit from this course.
Program Outline (1.2 CEUs / 12 PDHs)
DAY 1Overview of Commissioning and Start-Up
- Safety and training
- Case studies
Overview of Field Test Requirements
- Development of test regime
- Outline of typical tests
- Interpretation of test results
Basic Electrical Principles
- DC and AC circuit basics and laws, power factor, and bridge testing methods.
DC Voltage Testing Techniques
- Insulation resistance tests, step voltage and high voltage tests
AC Voltage Testing Techniques
- Power factor and dissipation factor tests, ac high potential test, and safety precautions
- Insulation resistance, high potential test, power factor test, dissipation factor, and voltage surge comparison testing
DAY 2Transformers Testing
- Polarity, terminal markings and connections
- Dry type transformers: inspection, acceptance tests
- Liquid type transformer: inspection, and acceptance tests
- Routine testing: AC high potential testing, TTR test, polarity test, induced potential test, polarization recovery voltage test, and DC winding resistance tests
- Insulation resistance measurement test, DC or AC high potential testing, power factor or dielectric loss test, and circuit breaker contact resistance test
- Insulation resistance measurement test, DC over-potential testing, voltage versus leakage current, power factor test, and cable fault locating
Commissioning of Electrical Apparatus and Systems
- Development of procedures
- Interpretation of results
Start Up, and Acceptance
- Energizing sequence
- Safety considerations
- Correction of defects
- A class-centered discussion on relevant maintenance practices will be conducted. Its intent is not to prescribe procedures and practices, but to alert participants to actual in-the-field imperatives that force the practitioner to deviate from recommended practices and what to do in order to minimize the consequences.
Forensic Engineering Aspects of Testing, Commissioning and Start-Up of Electrical Systems
- Applicable codes, standards and rules
- Conflicts involved in start-up
- What to do when disaster strikes
- Minimizing problems
