T-203H Handheld Three Phase Transformer Turns Ratio Test Set
DESP
T-203H automatic transformer turns ratio tester adopts three-phase
power supply output voltage, the test speed Instrument to adopt
advanced technology for A/D, wide range range; High speed ARM as
the core digital processor, test quickly; English menu display,
Elaborate and handheld design, makes the T-203H TTR tester superior
and powerful with small size and light weight. The TTR tester uses
a programmable signal source technology. It is especially suitable
for special transformers such as Z-type transformers, rectifier
transformers, Scott or anti-Scott transformers, etc. The T-203H TTR
tester adopts the new algorithm developed by our company to measure
the ratio of three-phase transformer and ensure the measurement
accuracy without adjusting the balance of the three-phase power
supply. Therefore, the transformer turns ratio and wiring method
can be measured in one minute.
FEATURES
- Input single power, internal digital combination standard sine wave
test source output
- Phase angle measurement function: measure the phase angle between
high voltage side and low voltage side. Measure the turns ratio and
phase angle of “Non integral point” transformer
- It can conduct single-phase measurement and three-phase winding
automatic test. Three phase turns ratio value, phase angle value,
error, tapping position, tapping value can be measured for once.It
also can identify connecting group number automatically
- Testing results can be displayed in the form of digit and hexagon
vector diagram, which makes transformer connecting group can be
made out obviously
- With blind test function: There is no need to choose connecting
method and group. When measuring Y/△, △/Y transformer, no external
short-circuit is needed, connecting method can be shifted
automatically according to the chosen testing contents
- With tapping test function: TTR and TTR error in the position of
each tapping switch can be gauged quickly. Just input rated TTR
once, instead of inputing over and over again, TTR error in tapping
position can be calculated
- With functions of turns ratio measurement and voltage TTR
measurement
- With 5.6 inch color LCD, the effect of data & figure display is
visualized and fine
- With small size and light weight, it is easy to carry
- With built-in high capacity chargeable lithium battery. Test can be
conducted without any power supply on site, and once the battery is
charged fully, it can make measurement for more than 500 times
continuously
