DAY TWO
SAFETY AND MAINTENANCE: MEDIUM AND HV EQUIPMENT
Main objective will be to discuss and demonstrate methods and typical results used for trouble shooting and evaluating electrical systems. Attendees will be shown methods of trouble shooting various systems and evaluating the findings. A basic understanding of insulation systems used in electrical equipment LV (up to 600 volt) and MV (up to 35KV). Delegates will be introduced to basic systems and tools which will aid in the detection, evaluation and recommendations for potential problems
encountered in typical electrical systems.

SAFETY AND MAINTENANCE: MEDIUM AND HV EQUIPMENT (CONTINUED)
INFRARED THERMOGRAPHY AND PREDICTIVE MAINTENANCE
Predictive electrical maintenance professionals utilize infrared thermal imaging cameras with integrated temperature measurement capabilities to allow them to make accurate assessments about the operating condition of electrical equipment targets. Significant temperature rise above normal operating parameters, that will compromise component reliability,
plant productivity and personnel safety, can be determined with confidence via thermal imaging cameras . Plus, temperature measurements collected and archived over time via thermal imaging cameras may be used to create an historical operating timeline – making the plant’s predictive maintenance program even more accurate and cost effective. With the help of simple analysis tools, thermographers can determine priorities for their predictive maintenance programs.
ELECTRICAL MEASUREMENT SAFETY: REDUCE THE LEVEL OF RISK TO YOURSELF AND IN YOUR WORK ENVIRONMENT
Taking measurement on electrical circuits can be made less hazardous by using test equipment the correct way. Electrical measurement tools like digital multimeters, electrical testers, oscilloscopes, current clamps and even test leads must be properly rated for the intended task.
In this seminar, attendees will learn current safety issues and discuss IEC61010-1 as it applies to our high energy, low voltage environment. Arc Flash reduction will be discussed as IEC61010-1 is implicated in the
NFPA 70E standard. Safe electrical measurement practices will be included as a review for everyone that makes measurements on electrical systems.
Presentation focus includes:
- Review examples and case study of safety incidents
- Understand common multimeter safety issues
- Learn about international safety specifications
- Understand over voltage categories and voltage withstands
CHOOSING THE CORRECT ELECTRICAL MAINTENANCE METERING METHOD AND TOOL
This innovative, hands-on presentation will present a wide range of basic electrical maintenance troubleshooting methods and a complete explanation and demonstration of how to choose the right meter for your testing needs. This is based upon troubleshooting techniques and common circuit problems. Larry Schultz will discuss voltage drop testing and series checking using a variety of voltmeters and do the same testing with an ohmmeter. The presentation will include a section on using an ammeter for preventive maintenance testing, which explains in detail the right and wrong way to use an ammeter.
PREVENTATIVE MAINTENANCE OF PROTECTIVE RELAYS
Preventative maintenance is a recommended practice for all electrical products to ensure system uptime and protection of assets. This presentation focuses on how to best manage the maintenance of your protection relays for generation, power distribution, motors, and switchgear to ensure the safe and reliable protection of your electrical equipment. Topics covered will include maintenance intervals, testing practices, and calibration.
