Transformer Winding Resistance & On-Load Tap Changer Test Set

1 Transformer Winding Resistance & On-Load Tap Changer Test Set Overview
The DC resistance test of the transformer winding is the essential test item of the transformer after overhauling, overhauling and changing the tap changer. At the same time, the on-load tap-changer is the only moving part connected with the transformer circuit, so the on-load tap-changer test is very important. R & D and production of our company has developed a transformer DC resistance and on-load tap-changer integrated tester, the instrument can only be one-time wiring can be two tests: direct resistance test and on-load tap-changer test. And the use of wireless temperature measurement technology, real-time monitoring of the transformer oil temperature, the DC resistance value of a unified conversion to 75 ℃ evaluation criteria more accurate and reliable.

2 Transformer Winding Resistance & On-Load Tap Changer Test Set performance characteristics
2.1 at the same time with direct resistance test and on-load tap-changer test function, one-time wiring, the completion of two tests, simple and convenient.
2.2 For the star connection with neutral point winding winding test, the instrument can take three-phase simultaneous measurement of the way to test the three-phase DC resistance, saving test time. And the first test of the A0 phase data, and then three simultaneous test to solve the three-phase simultaneous test neutral point lead resistance can not be tested, the test data closer to the single-phase test value.
2.3 For the Y-type and △ -type winding test, the instrument can be three-phase automatic test and three-phase unbalance rate.
2.4 Instrument comes with wireless temperature measurement, real-time monitoring of transformer oil temperature.
2.5 The instrument adopts the operation mode of button plus jog shuttle, which is flexible to use and easy to operate. Especially for the operation optimization of on-load waveform analysis function, it greatly improves user's using efficiency and operability.
2.6 with local storage and USB storage, including the machine can store a load test results 200, the direct resistance test results 200, and the local storage can be transferred to the USB flash drive; in the USB storage test results transition Waveform and other information directly saved as BMP image format, direct resistance test results directly saved as WORD format, user-friendly direct printing on the computer to view.
2.7 Power-off clock and date display.
2.8 thermal printer printing, fast, silent.
2.9 man-machine interface more friendly.
2.10 small size, light weight, easy to carry.
