Product Description
Transformer DC resistance is a must-test item in transformer
manufacturing for semi-finished products, finished products,
factory test, installation, overhaul, after changing the tap
changer, handover test and preventive test in the power sector. You
can check the welding quality of the winding joints and whether the
windings have short-circuits between turns. You can check whether
the contact of each position of the voltage tap switch is good,
whether the actual position of the tap changer matches the
indicated position, and whether the lead wire is broken. Whether
there is stock breakage, etc. In order to meet the needs of rapid
measurement of transformer DC resistance, the XHZ1010S transformer
DC resistance tester developed by our company.
The instrument adopts a brand-new power supply technology, which
has the characteristics of small size, light weight, large output
current, good repeatability, strong anti-interference ability, and
perfect protection functions. The whole machine is controlled by a
high-speed single-chip microcomputer, with a high degree of
automation, with automatic discharge and discharge alarm functions.
The instrument has high test accuracy and easy operation, which can
realize rapid measurement of transformer DC resistance.

display under strong light
The instrument has its own power-down storage, which can store 1000
sets of test data, which can be consulted at any time.
