Circuit Breaker Testing Fundamentals
Doble Engineering Company
Special Testing Methods – Dynamic Resistance
Doble Engineering Company
Performing timing tests on high voltage circuit breakers will provide information about contact synchronization in relationship to opening and closing times for the breaker under test and in certain cases some insight as to the quality of that breakers arcing contacts. But, for a more detailed indication of a circuit breakers arcing contact erosion we can also employ the ‘dynamic’ resistance measurement method also known as DRM. The advantage of injecting high DC current and measuring the voltage drop during the circuit breakers full speed motion can provide a detailed picture of the arcing contacts condition. Knowledge of circuit breaker arcing contact system design is necessary for best test results analysis. This presentation will address how, when, and why this advanced diagnostic measurement method should be used in order to extract maximum knowledge of your circuit breakers arcing contact condition.
Morning Break
Maintenance & Repair — Lubrication
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.
Maintenance Done Right
Jim McLean, North American Sub-station Services
This presentation discusses the different topics that are needed to make the best decisions for maintenance on your OCBs. Doing maintenance is only a portion of the complete service for the OCB. Better decisions can now be made by utilizing improved parts, improved testing, oil filtration as well as the total quality of the maintenance being performed. It also discusses the decision that you need to make with oil filtration verses particle count in the oil.
Special Testing Methods – Using Infrared Thermography in Assessing Substation Equipment Conditions
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.
Industry Expo & Lunch
Hyatt Regency Atlanta
SF6 – the Alternative Gas
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.
Oil Testing of Circuit Breakers
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.
Afternoon Break
Leak Repair
Colt On-LIne
Scrapping Breakers
Safety considerations and best practices for scrapping circuit breakers are addressed in this session.
Expo Marketplace
Hyatt Regency Atlanta
Attendees schedule 15-minute meet & greet appointments with Industry Expo exhibitors. Make new contacts, see new products and have questions answered.
