Use the Megger ‘Best Practices’ Seminar to help improve your business skills, share insights, and address many of the challenges seen in the industry today. Sessions will include paper sessions on the practical aspects of ensuring reliability including common methods and practices with applicable test equipment.  Here is a list of some of the topics currently under review for the 2012 Best Practice event:

Impedance and Load Testing Techniques
In this presentation, you will see that a battery plays a very critical role and is a complex electro-chemical device. Terms and definitions associated with batteries and battery components will be reviewed and  discussed along with a review of various failure modes. Batteries require maintenance and care to ensure their state of health. Different levels of maintenance, various testing methods along with data analysis will be discussed. We will also review NERC PR-005-1 and PR-005-2 Draft.

Testing, Reading Prints, Making the Connection
We test HV Breakers to make sure they are still operating up to par so that when they are called upon by relays to isolate precious capital investments….they will. With today’s variety in breaker design and applications, it may be difficult to know where to connect your Breaker Timer. Basic
breaker operations along with open/close control circuit diagrams will be illustrated.

Trip Testing
What if your breaker has been in the field for 5 years and has not been tested? What if it has never even operated during that time? You may want to perform a test the very first time you trip that breaker and
capture that data. First trip testing with coil current monitoring will be discussed.

Static Resistance Measurement (SRM)/Dynamic Resistance Measurement (DRM)
The Static Resistance Measurement (SRM) is a technique to identify switchgear breakdowns caused by high contact resistances across bus bar joints, breaker contact points and isolators. Dynamic Resistance Measurement (DRM)
is a test method used as a diagnostic and analysis tool. One of the main objectives of the DRM technique is to determine the length of the arcing contact. The importance of these tests will be discussed in further detail.

(High Voltage), EHV (Extremely High Voltage), GIS (Gas Insulated
Switchgear), GCB (Generator Circuit Breaker) Applications
Any of these scenarios could cause a bead of sweat to pop up on the brow of any user when confronted with performing the appropriate tests. We will look at using Dynamic Capacitance Measurement (DCM) as a method of testing a breaker when it is not practical to lift one ground. This key factor to performing these tests safer, and more efficiently will be addressed.

By recording the vibration signature of a breaker’s operation, you collect data that can be used for an efficient and non-invasive comparison in an on-line test at a later stage. Mechanical vibrations from the
operating mechanism and breaker chamber can be identified and changes in time and magnitude reveals if something internal has changed that requires an off-line maintenance test. We’ll show you how.

Plans and Reporting
How do you know if you are measuring the breaker to the correct
manufacturer and standard specifications? A correct test plan with well-defined
parameters is a necessity for producing reliable and accurate results. Variable parameters
such as speed calculation points, pulse times, and others will be discussed along with interpretation of the results.

in condition analysis and assessment of Power Transformers
Transformer Turns Ratio (TTR)- Every transformer is made up of a set number of turns on the primary side relative to the number of turns on the secondary side. Do you have the right equipment to test your transformers for possible damage? We’ll help you figure it out.

Power Factor
Insulation is crucial for maintaining engineered distances between live parts and ground potential. Power factor insulation testing can help determine your equipment’s acceptable limits. We will be available to help you understand the test terminology and testing procedures so you can determine when preventative action should be taken.

Sweep Frequency Response Analysis (SFRA)
When transformers are moved or when they experience a large through fault, mechanical deformations can appear within the transformer. The best way of identifying issues before they become a problem is to perform a
Sweep Frequency Response Test, and compare the results with previous tests or manufacturer results. Discussion will include how to properly use sweep frequency analysis for transformer inspection.

IDAX (Insulation Diagnostic Analyzer) Technology
The IDAX technology provides a new, reliable, and convenient way to assess moisture in transformer insulation. In this segment we will look at factors that can improve the useful life of your transformers and help you
avoid catastrophic failures caused by moisture or contamination in your transformers.

Data Collection, Trending, and Analysis
We’ll share insight on how many companies are coping with the new NERC (North American Electric Reliability Corporation) and FERC (Federal Energy Regulatory Commission) and data collection, and management

You will have one-on-one interaction with industry experts and whether you are a customer, a partner, or an industry expert, our event is created specifically to bring together the industrial community to share knowledge, exchange ideas, and realize its full potential. Don’t miss out on this fantastic opportunity to ask questions specific to your
maintenance and testing needs. And best of all it’s free! Sign up early as spaces are limited.
