The latest TTR available from Megger is the TTR100, a handheld, robust, lightweight and battery operated instrument. This TTR will complement several existing Megger transformer test products and will offer switchable functions, such as winding resistance and polarity. It is the only instrument in the market place that displays both tested and expected polarity results. With a turns ratio of 20,000:1, the TTR100 offers the highest turns ratio accuracy in the industry of 0.1%.
The TTR 100 is used to perform tests in the field, as well as in manufacturing facilities and repair centers. Improved testing productivity is achieved in these environments through the efficient collection and storage of large amounts of data, which can then be uploaded to a PC database for analysis and test results reporting.
