FULL-DAY ELECTRICAL MAINTENANCE TRAINING TUTORIAL

Your facility depends on electrical power to run profitably day in and day out. That's why it makes sense to test your electrical equipment -- prior to acceptance, and afterwards -- to ensure safe, reliable operation. By performing regular maintenance tests you become aware of the hidden problems in your electrical system - before they become disasters. In effect, you may avoid expensive failures and unscheduled outages, and most importantly, personal injury.

The best way to ensure that your testing program meets all your maintenance objectives is by understanding and following electrical maintenance testing standards developed and used by professional electrical testing organizations, such as NETA. NETA (The International Electrical Testing Association) is recognized by the American National Standards Institute (ANSI) as an accredited standards developer and is an independent, third party electrical testing association dedicated to setting worldwide standards in electrical maintenance and acceptance testing.

This one-day Electrical Maintenance Training course is designed to provide electrical maintenance personnel with the what, why and how of electrical maintenance testing. By reviewing electrical testing specifications developed by NETA, maintenance personnel can create a maintenance program designed to meet your facility's needs. It will also help them decide what can be done by in-house personnel and what is best left to an accredited electrical testing professional.

THIS Electrical Maintenance Training Course ALSO INCLUDES PRESENTATIONS ON:

  • Electrical Tests for Industry
  • Power Transformer Maintenance
  • Circuit Breaker Timing Tests
  • Grounding, Ground Resistance and Soil Resistivity Testing
  • Cable Testing: Evaluating the Health of Service Aged Cable
  • What's Hot in Infrared Thermography
  • Condition-Based Maintenance: Utilizing Monitoring and Diagnostic Data to Drive the Maintenance Decision Process

OFFERING AN INTERACTIVE, PROBLEM-SOLVING, Electrical Maintenance Training LEARNING ENVIRONMENT
As well as helping delegates keep abreast of the latest technologies and techniques available in this area, this forum offers an excellent opportunity for delegates to ask specific questions and exchange ideas relating to their own applications. This is designed to be an interactive, problem-solving, learning environment for delegates of all disciplines.

DAY 2:

9:05 am

Electrical Tests for Industry

In any environment, it is vital to know how to determine that machinery is operating improperly.

We will profile some of the test equipment that electrical personnel should have to perform the usual testing and how to do so safely.

We will describe procedures that qualified electrical personnel can perform with these instruments to troubleshoot modern industrial plant electrical equipment. Basic problem solving techniques also will be discussed.

We will cover:

  • Acceptance testing of delivered equipment.
  • Troubleshooting of installed equipment.
  • Other matters of interest to the audience.

9:45 am

Power Transformer Maintenance

Since the early days of electricity it was quickly learned that a transformer was needed to efficiently convert system voltages both upward and downward for the purposes of transmission, distribution and utilization.

The transformer contains no moving parts and performs its job in an almost perfect manner. However, year after year hundreds of them fail. In virtually every case these failures can be detected through simple cost effective preventative maintenance techniques that can be performed during an annual substation maintenance shutdown but also during your regular working day.

The failure of a power transformer can be a crushing blow to your business. The initial cost of the actual repair combined with the costs for temporary rentals and lost production can be staggering.

In today's economy it behooves us to use our money wisely in preventing failures of this nature.

10:30 am -- Coffee Break

10:45 am

Circuit Breaker Timing Tests

The circuit breaker is the most important and complicated of all types of power circuit interruption equipment. Incorrect operation can have disastrous consequences on the equipment or the substation personnel. Not to mention loss of revenue caused by being out of service and repair costs.

The timing of a breaker is the time measurement of its mechanical operations and is done to verify its integrity and working order. Timing tests are done first in the factory during routine testing and after installation, during the commissioning tests. These tests also have to be done periodically in order to ensure the good working order and reliability of the breaker. Timing tests are also a powerful tool for troubleshooting faulty breakers.

11:30 am

What's Hot in Infrared Thermography

With examples from experienced infrared thermography experts, this presentation offers a useful exposure to everyday mission-critical, heat-related maintenance issues.

Thermographic analysis, if performed correctly, can precisely locate and distinguish anything from loose connections to circuit overloads to motor shaft misalignment; done incorrectly and uptime can become downtime in a hurry. Indirect measurements, environmental influences and an absence of a pro-active maintenance focus can negatively impact the success of a predictive maintenance program.

Utility and independent thermography professionals provide real-world examples of incidents caught, cost-savings recouped and the challenges involved in finding 'What's Hot'.

12:15 pm -- Luncheon

1:15 pm

Cable Testing: Evaluating the Health of Service Aged Cable

This presentation will focus on an effective, precise and conclusive way to test older service aged cables for their future reliability. A new approach will be discussed with a view towards reducing unneeded cable stress while testing for both service aged and new cables. The replacement of the traditional hipot set will be addressed, offering instead, very low frequency technologies.

Topics to be covered include:

  • Current practices for PILC, PE, early XPLE cables, advantages and shortcomings
  • State of the art testing update, with advantages and disadvantages
  • Several case studies will done, both industrial and utility based.

2:00 pm

Grounding, Ground Resistance and Soil Resistivity Testing

This presentation will include a brief review of grounding fundamentals. Particular emphasis will be paid to the definition of soil resistivity and grounding. As well the presentation will discuss test methodologies used to perform soil resistivity testing and ground resistance tests. The Wenner method used for soil resistivity testing will be presented. Three different types of ground resistance tests will be discussed: fall of potential, selection and clamp-on (stakeless). The difficulties associated with each testing approach will be explained.

2:45 pm

Condition-Based Maintenance: Utilizing Monitoring and Diagnostic Data to Drive the Maintenance Decision Process

Faced with increased demands and growing competiton, many utilities and industries are seeking to maximize the value of their existing assets by leveraging new technologies to optimize Operations and Maintenance activities. One of the most successful maintenance strategies is a conditioned-based approach which utilizes data collected from periodic inspections, testing and predictive maintenance technologies to determine the optimum maintenance requirements. Contrary to the traditonal time-based maintenance approach, Condition-based Maintenance is a process, which utilizes monitoring and diagnostic data to drive the maintenance decisioin process.

Topics to be discussed include:

  • Data Management vs. Work Management
  • Automating the data collection process
  • Maximizing how data is utilized for maintenance decision making
  • Integrating periodic condition monitoring into the maintenance work process
  • Automating CBM data analysis and management
  • Utilization of the internet to implement advanced asset management strategies across the enterprise
