3V - 300V Transformer Winding Deformation Tester Short Circuit
Impedance Test
Low-voltage short-circuit impedance test is to the most direct way
to check the deformation of the winding after transformer suffered
from short-circuit current or mechanical collision during
transportation and installation, the test is important to help
determine whether the transformer can be put into operation, and
whether disintegration is necessary for inspection. ZX-BZK
transformer short-circuit impedance tester comes with adjustable
power output, particularly suitable for 110kV and above main
transformer on site measurement.
Features
1. With switching power supply, just one time wiring connection can
finish measurement for all the windings, no matter it is single
phase transformer or three phase transformer
2. Single phase measurement mode. To three phase transformers, each
phase short circuit impedance, reactance, inductance can be obtained automatically after three times
boosting.
3. Adopts phase locking technology, synchronize sampling AC signal
which ensures accuracy
4. current, voltage and power, frequency can be measured at the same
time
5. Support external connection with CT/PT to extend measuring range
6. With memory to store data, with printer
7. LCD display with operation menu, data can be read clearly even
under direct sunlight
