Your local IEEE PES/IAS Chapter is offering this 6 hour training on Electrical Safety in the Workplace by John Leedy, Owner of Leedy Electric East.

This training session will be devoted to the subject of Electrical Safety in the workplace as it relates to the latest edition of the NFPA 70E-2015 and the updates contained therein. Topics such as “how does electrical safety and the NFPA-70E apply to the workplace” and “what is required to be compliant with the standard” will be covered.

A copy of the standard, NFPA-70E-2015 Standard for Electrical Safety in the Workplace is included in the training costs.

 

Additional Information

John Leedy graduated from University of Florida in 1982 with a Bachelor of Science in Electrical Engineering with an emphasis in Power Delivery. John worked for Dillard Smith Construction as a protective relay technician. He joined General Electric as a Field Engineer, specializing in Power Substations and DC Electronic Drive Systems in Paper Mills as well as Project Management of Paper Machine Drive System retrofits and substation construction and commissioning. John left GE to join the family business, Leedy Electric Corp, in 1987. He earned his PE license for the State of Florida in 1992 and the State of Georgia in 2013 and received his Masters in Engineering Management from the USF in 2002. John has been working with NFPA 70E regulation since 2002, performing hundreds of Arc Flash Risk assessments throughout the SE United States,training management and employees on the standard. Leedy Electric is located in Mulberry Florida, and has been in business since 1975, specializing in Engineering and Electrical Service for the commercial and industrial industries.

The Advantages of Using Continuous Infrared Monitoring

Thermal Monitoring in the Past

Thermal inspection has long been recognized internationally as the top method of identifying poor termination, the cause of many power outages. In the past, thermal imaging inspections were typically conducted one or two times a year from outside the enclosure where the equipment was housed. In addition, it could only be used for components that were within a direct line of sight and adjacent to the panel surface. This led to power failures, as well as long and expensive periods of downtime.

When thermal windows were introduced, they did improve the problem somewhat by providing a better view from the camera to the target. However, they were unable to put an end to many of the most important issues, like how to inspect targets that were not within a direct line of sight or the fact that inspections were rarely completed.

The Importance of Continuous Infrared Monitoring

Continuous infrared monitoring puts an end to this problem by providing uninterrupted thermal monitoring of mission critical electrical equipment from within the enclosure, as opposed to intermittent inspections conducted from outside where the equipment is held. As a result, continuous infrared monitoring, such as that offered by Exertherm™, has the ability to detect and identify the specific location of any potential problem before it can result in power failure. In addition, it can be used to gather trends and plan future load distribution.

How Does Exertherm™ Continuous Infrared Monitoring Work?

Small, plastic IR sensors are placed inside the enclosure where they can directly monitor key connections. In addition to these sensors being non-contact, they also require no external power. Cable joints can also be monitored via a patented cable sensor which is strapped to the cable and provides delta T measurements. They are then connected to a data card that has the ability to filter, linearize, and condition the signal from up to 8 various sensors. They collect condition and pass on the data to the host system. This allows for the thermal monitoring of all critical equipment.

Continuous Infrared Monitoring Has the Features You Need to Predict Electrical Power Failure

Trend analysis can be combined with the delta T readings in order to create a thermal map. Then, the thermal map can be used to provide the normal delta T value at any given load. Any variance of the delta T is indicative of a potential problem that needs to be addressed. Generic low and high level alarms are programmed to indicate fault levels regardless of load. You also have the option of adjusting the alarm levels to suit your specific conditions.
Screens give users the opportunity to view sensor readings and alarm status as a group or individually to identify discrepancies between phases and sensor locations. This allows for easy recognition of problems.

Thermal mapping can also be used to justify extended periods of time between invasive maintenance. This helps you avoid downtime, while also saving money. In addition, you can view the degeneration of equipment over a lifetime to help you more accurately plan an equipment replacement program.

All over the world, Exertherm™ is gaining acceptance and being deployed on major products to mitigate key risks in critical power systems.
