Now that the "Information Super Highway" is upon us, you might be feeling a bit behind the times if you’re not yet tracking your test data through the computer and software. Fear not, many customers still manage the "paper mill" of laboratory test reports. For most though, there exists a point where data tracking is not only desirable, but a necessary requirement for a properly managed transformer maintenance program. Depending upon the extent for your involvement in the test data and its interpretation, data handling and tracking can range from a simple word processor document to quite complex, analytical diagnostic software now offered in the industry.

Many will find this method of tracking to be an adequate system. However, except for the customary scheduling of maintenance and sampling intervals, there is not much in the way of data management that be accomplished with this type of tracking system.

Now, with the spreadsheet’s sorting function you can rank your test data by any field. This is probably the most powerful feature of the spreadsheet which enables you to schedule by time intervals and note severity. Graphing is another powerful feature which of course gives you a graphical interface to your data. Skilled spreadsheet users can go the next step further and write diagnostic macros (mini-programs) which take your data and crunch it though several equations and filters to output meaningful diagnostic results. Since it offers so many advantages, many of our customers have utilized this method of data tracking.
