Transformer loss measurement system TLMS

Transformer Loss Measuring System plays an important role in the quality inspection of the transformer. The transformer loss can be no-load loss and load loss. Because of the improvement of processing and the new material application, the no-load loss is much lower than before, so is the power factor of load loss. Therefore, the requirement for the measuring range and accuracy in transformer loss measuring system is increasing higher and higher.
TLMS System have the high accuracy in the big range of10V~100kV,0.5A~4000A. Its error is no more than 1.15% with the power factor of less than 0.008, which does completely match the requirement for the transformer loss measurement at present. The measurement tap is changing at its secondary side and the software can adjust the measurement range in automatic way. Such method makes the test much simple and more efficient since the engineer need not to change the tap in the primary side for each test section.
TLMS System has its current measurement section with two current transformers in series. One is for small range, the other is for big range. While, its voltage measurement section. uses the standard electronic voltage divider for its voltage measurement, which features good linearity, wide range and low angle error, higher than 0.005 class in the full range.
TLMS System will use the power analyzer of NORMA 5000 or WT5000, which are the most popular ones in the market with good reputation. The customer can choose any of them to work with our system.,
TLMS System has its own software which combines many functions and advantages from other international transformer loss measuring systems. Moreover, some special functions are developed such as test data uploading to grid company base, real-time waveform display and analysis.
TLMS System features high quality, compared with other transformer measuring system. Its automatic switch ca avoid the mis-operation by the engineer. Its good insulation structure improves the system in EMC, EMI and which protect the system and test object from the damage by the self-discharge and transmit over-voltage.
