ZX-BZK Transformer Short-circuit Impedance Tester

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.
