Circuit Breaker Testing Fundamentals
Joe Brown, Technical Application Engineer
Doble Engineering Company
Special Testing Methods – Infrared Thermography
Ed Kochanek,Director of Sales Eastern Region
FLIR Systems, Inc.
Performing infrared thermography inspections has become an integral part of substation maintenance as a tool for prevention of failures. This presentation will offer a brief overview of infrared thermography as it applies to detecting the common problems in and around substation equipment – specifically disconnect switches, circuit breakers, shunt reactors and in some cases current transformers. The presentation will also highlight the effect of infrared camera resolution in identifying potential issues and the repairs required to correct hotspots.
Specialty Testing Methods – Partial Discharge Surveying
Joe Brown, Technical Application Engineer
Doble Engineering Company
Morning Break
Oil Testing of Circuit Breakers
David Koehler,Technical Manager
Doble Insulating Materials Laboratories
The condition assessment of Bulk Oil Circuit Breakers (OCBs) can be achieved via laboratory insulating liquid testing. OCBs can fail mechanically, electrically, and from overheating issues. Technical information of each recommended laboratory test, along with case studies will be provided.
Circuit Breaker Asset Management & Replacement Programs
Jeff Hefner, Substation Support Supervisor
Brian Youmans, Senior Engineer
Georgia Power
In today’s modern utility, capital investments in transmission and distribution assets can be on the order of billions of dollars. With all that spending, there is enormous pressure to ensure that we are making the right decisions with regard to managing risk and ensuring the reliability of our system. With the ever-increasing amount of real-time asset health information that is available to the asset manager, as well as all the traditional database type condition information obtained from preventative maintenance, the sheer amount of data can be challenging. This presentation will discuss Georgia Power’s approach to circuit breaker fleet asset health indexing and replacement planning.
Lubrication Techniques for Circuit Breaker Mechanisms
Jack Harley, President
FirstPower Group
Functional operation of many older circuit breakers may be effected by the condition and type of lubricants used in the mechanism and the method of lubricant application. Options for lubricant selection and factors to be considered for different components and environments will be presented. Selection and application factors are based on field observations, laboratory and simulator tests and best practices.
Industry Expo & Lunch
Oil Circuit Breaker Maintenance & Extending Maintenance Cycles
Jim McLean, Director of LTC Business
North American Substation Services
Safety First: New Cubicle Inspection & Repair Safety Device
Eric M. Fell, Specialist – EH&S Safety
Consolidated Edison Company of New York
The Cubicle Inspection & Repair Safety (CIRS) Device (patent pending) provides a safer work environment within switchgear cubicles by eliminating the risk of accidental/incidental contact with energized bus components. The device provides mechanics the ability to safely perform inspections, preventative maintenance and corrective maintenance without the need for a bus section outage. The device is currently being piloted throughout the Con Edison territory and has already proven to be a safe and reliable solution when deployed for emergency corrective maintenance events.
On-Line SF6 Leak Repair
Jim Hackett, Power Services Division Manager
The Colt Group
Repair of gas and oil leaks should be regarded as a critical component of an apparatus maintenance program. When a leak is identified and immediate re-gasketing or replacement is not feasible, a temporary solution should be a scheduled to stop the leak. Learn how oil, SF6 and nitrogen leaks can be immediately repaired with minimal outage time and reduced resources – no epoxies or welding. This presentation will explain the repair methodology and benefits. Numerous customer examples will be shown to illustrate the business case and justification.
SF6 – the Alternative Gas
Billy Lao, General Manager
Dilo Company Inc. & Dilo Direct
With the ever growing challenges of federal & local reporting and SF6 emission reduction, a number of alternatives have been presented to the industry in replacement of SF6 gas. However, as the industry continues to review and consider the alternatives, we should not limit our solutions. SF6 continues to be the best alternative to medium and high voltage electrical insulation and arc quenching in GIE. By turning to the existing stockpile of SF6 gas available, we will lower our carbon footprint while meeting the requirements for SF6 gas in new and in-service equipment.
Afternoon Break
Step-by-Step Instructions for SF6 Handling during Breaker Maintenance
Billy Lao, General Manager
Dilo Company Inc. & DILO Direct
Traditionally, SF6 gas handling was considered a task to be completed in the field as an afterthought and only a minor part of the overall scope of work. Considering the evolution of regulations, improvements in technology, and requirements for improved processes, SF6 gas handling is now an intricate part of any GIE installation, maintenance or replacement. Understanding and implementing best practices and processes ensures accountability and environmental responsibility.
