Transformer loss measurement is an essential step in transformer quality inspection. Transformer loss is divided into empty load loss, and load loss, due to the improvement of the process and the application of new materials, the value of empty load loss is getting lower and lower, the power factor of load loss is getting lower and lower, which puts forward higher requirements for the test range and accuracy of transformer loss measurement system.

TLMS series transformer loss measurement system can achieve a maximum of 10V-200kV, 0.5A-4000A under the full range of high-precision measurement, power factor as low as 0.008 loss high-precision measurement, the error is not greater than 1.25%, fully meet the loss measurement needs of modern transformers. The use of secondary side switching, can automatically match the appropriate range in the full measurement range, to achieve load switching, eliminating the need for manual side switching, improve test efficiency.

The current measurement section uses a current transformer, using a one-sided series transformer structure specifically designed for transformer loss measurement systems, with one transformer responsible for low measurement range and another for high measurement range. The voltage measurement section, with its standard electronic voltage divider, offers unparalleled linearity, measurement range and very low angular differences. Full measurement range is possible, with angular differences better than 0.005.

The TLMS series transformer loss measurement systems use NORMA5000 or WT5000 power analyzers, which are the best precision power analyzers available on the market. Can be freely selected according to customer needs.

TLMS series transformer loss measurement system has a set of powerful and intelligent software, integrated with a variety of foreign transformer loss measurement system software features and advantages, but also for China's national conditions to develop additional features, such as test data real-time upload national network database, real-time waveform display analysis and other functions.

Compared with other types of domestic and imported transformer loss measurement systems, the TLMS series transformer loss measurement systems also offer unparalleled reliability, automatically switching gears, and effectively avoiding the consequences of misoperation by testers. Specially strengthened insulation design, in EMC, EMI, EMP protection has made great progress, equipment is not easy to pass voltage test and the test subject itself discharge under the condition of damage.
