AVO Training Institute - Substation Maintenance I
2013-06-27 18:08:00| Transmission & Distribution World
Substation maintenance is a key part of any plant's maintenance program. Failures in key components such as racking mechanisms, meters, relays and buses are the most common cause of unplanned outages. Power transformer failures may result in significant downtime and long delays in equipment replacement. Most of these failures can be detected and prevented. Having skilled substation maintenance technicians is essential to equipment reliability. Location Various Locations United States See map: Google Maps Course Duration: 4.5 days Credits: 3.6 CEUs Level of Involvement: Hands-on Schedule: 8:00am - 4:30pm, the final day ends at 12:00pm Locations: Dallas, TX; Pasadena, CA; Portland, OR; Valley Forge, PA Course Number: 230 Tuition USD: $ 1770 Substation maintenance is a key part of any plant's maintenance program. Failures in key components such as racking mechanisms, meters, relays and buses are the most common cause of unplanned outages. Power transformer failures may result in significant downtime and long delays in equipment replacement. Most of these failures can be detected and prevented. Having skilled substation maintenance technicians is essential to equipment reliability. Learning Objectives • Identify safe work procedures • Explain the configuration and function of common equipment found in a substation • Identify components of air, oil and vacuum circuit breakers, and metal-clad switchgear (including switchyard equipment) • Perform and interpret results of insulation resistance and contact resistance tests on medium-voltage circuit breakers and switchgear • Perform overpotential and vacuum integrity tests, measurements and make adjustments to medium-voltage circuit breakers • Perform and interpret results of a tank loss index test on an oil circuit breaker (as needed) Who Should Attend This hands-on course is intended for apprentices, technicians and engineers responsible for the maintenance and testing of industrial and utility substations. Requirements This course requires working knowledge of basic electricity. Students must wear long pants and safety toe shoes to complete the lab portion of this course. No shorts or sandals will be allowed. **This course is available in both English and Spanish. read more

AVO Training Institute - Circuit Breaker Maintenance (Medium Voltage)
2013-06-27 18:08:00| Transmission & Distribution World
Unlike a low-voltage breaker, medium-voltage breakers rated at 1 kV or higher rely on external controls to operate effectively. That means technicians have more components to test and maintain to ensure a 3 to 5 cycle operating time. Failure of one of these breakers can cause catastrophic damage to other equipment and is extremely hazardous to nearby personnel. With safe and proper maintenance, technicians can ensure that tripping operations execute as required for equipment protection. In addition to improving electrical system reliability, well maintained circuit breakers also minimize the arc flash hazard energy levels that technicians can be exposed to during a fault. Location Various Locations United States See map: Google Maps Course Duration: 3.5 days Credits: 2.8 CEUs Level of Involvement: Hands-on Schedule: 8:00am - 4:30pm, the final day ends at 12:00pm Locations: Dallas, TX; Valley Forge, PA Course Number: 300 Tuition USD: $ 1440 Unlike a low-voltage breaker, medium-voltage breakers rated at 1 kV or higher rely on external controls to operate effectively.

In addition to improving electrical system reliability, well maintained circuit breakers also minimize the arc flash hazard energy levels that technicians can be exposed to during a fault. Learning Objectives • Identify components and insulation mediums for all vacuum and air magnetic circuit breakers • Utilize appropriate personal protective equipment and safe work procedures including lockout/tagout • Evaluate breaker ratings for various applications • Interpret control schematics • Explain removal and restoration procedures • Adjust linkages, switches and contacts • Perform circuit breaker maintenance service per NETA specifications • Perform and evaluate the results of contact resistance, insulation resistance, leakage current, power factor, timing and bottle integrity tests Who Should Attend This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot air and vacuum metal-clad circuit breakers and switchgear, rated at 1 kV and higher. Requirements The student should have basic knowledge of AC/DC electricity. Students must wear long pants and safety toe shoes to complete the lab portion of this course. read more

AVO Training Institute - Transformer Maintenance and Testing
2013-06-27 18:08:00| Transmission & Distribution World
While the operating principles of transformers have remained the same for nearly a century, the challenges of maintaining and testing transformers have evolved along with transformer design and construction. Modern transformers are designed to closer tolerances than ever before. Proper testing is essential for evaluating the condition of a transformer. This predictive data will guide maintenance activities and help prevent catastrophic failure that damages downstream equipment and endangers personnel. Location Various Locations United States See map: Google Maps Course Duration: 4.5 days Credits: 3.6 CEUs Level of Involvement: Hands-on Schedule: 8:00am - 4:30pm, the final day ends at 12:00pm Locations: Dallas, TX; Valley Forge, PA Course Number: 142 Tuition USD: $ 1590 While the operating principles of transformers have remained the same for nearly a century, the challenges of maintaining and testing transformers have evolved along with transformer design and construction. Modern transformers are designed to closer tolerances than ever before. Proper testing is essential for evaluating the condition of a transformer. This predictive data will guide maintenance activities and help prevent catastrophic failure that damages downstream equipment and endangers personnel. Learning Objectives • Identify power/instrument and distribution transformer types, components and auxiliary equipment • Evaluate transformer configuration for the application • Interpret nameplate data • Perform and evaluate the results of insulation resistance, winding resistance, turns ratio, core excitation and power factor tests of windings, bushings and liquid insulation • Utilize a frequency response analyzer to identify damage • Calculate polarization index and temperature corrections • Perform oil sampling, testing, drying, filling and filtering • Explain gas sampling and testing • Combine test results to troubleshoot transformer problems Who Should Attend This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot power transformers rated 765 kV or less used in utility and industrial applications. Requirements The student should have basic knowledge of AC/DC electricity. Students must wear long pants and safety toe shoes to complete the lab portion of this course. read more
