Product Description
The transformer DC resistance is a required test item for the
factory test, installation and handover test of semi-finished
products and finished products in transformer manufacturing, as
well as the preventive test of power department. It can effectively
find the manufacturing defects such as material selection, welding,
loose connection parts, missing stocks and broken wires of
transformer coils and the hidden trouble after operation.
In order to meet the need of rapid measurement of transformer DC
resistance, our company developed a transformer dc resistance
tester with its own technical advantages.The instrument is a new
generation of rapid tester which integrates single phase test and
three phase test (Yn, Y, △) functions, and is an ideal equipment
for measuring DC resistance of large power transformers.The screen
adopts large screen and high resolution liquid crystal display
screen, which is convenient to use on site. It has the function of
Chinese menu prompt, simple and intuitive operation, and all the
direct resistance test items are completed in one connection, with
fast test speed, high accuracy and wide range.

Feature/Function
1. For the winding test with star connection and neutral point lead,
the instrument can adopt the method of three-phase simultaneous
measurement to test the resistance of A0, B0 and C0 phases, which
can save the test time.Moreover, the A0 phase data is tested first,
and the same phase data is tested again and again at the same time,
which solves the problem that the resistance of the neutral point
outlet line cannot be tested when the three phases are tested at
the same time, and makes the test data closer to the test value of
the single phase..
2.For Y and △ winding test, the instrument can carry out three -
phase automatic test, and calculate the three - phase unbalanced
rate.
3.The functions of magnetic method and degaussing, which can meet
various requirements of field test.
4.Variety of protection functions, such as anti-electromotive force
protection, wire breaking protection and power failure protection..
5.Wide measuring range, up to 200 Ω, high precision.
