RSZZ-5A High Precision Transformer DC Resistance Tester
DC resistance measurement of transformer winding is a very
important test project. In the "electrical equipment test
procedures", it ranks second in transformer test project.
"Electrical equipment test procedures" provides that it is
necessary to measure the DC resistance of transformer windings
during transformer transfer, heavy maintenance, and light
maintenance, changing tap joint position, troubleshooting and
pre-test, which aims to:
1. Check the welding quality of lead and down-lead within the
winding;
2. Check whether the contact of each tapping switch position is
good.
3. Check whether the winding or down-lead is broken.
4. Check whether the parallel branch is correct and whether the
winding winded by several parallel wires has one or several
disconnection.
5. Check whether layer or inter-turn is short circuit.
Product Features
1. Controlled by micro-computer, can save test results.
2. CD backlit display to the instrument makes it easy to operate.
3. Use current source linear compensation technique not only
improves efficiency, speed and measurement accuracy, but also makes
the test stable. This reduces the operator’s work intensity.
4. Adopting “four-terminal” measurement method in technical, it
eliminates the measurement error caused by down-lead resistance and
contact.
5. Panel printer can quickly print measurement results (optional).
6. The instrument with Over-voltage protection devices can prevent
the impact of counter electromotive force.
7. The instrument is small size, light weight, and easy to carry.
8. This equipment applies to measure and analysis all kinds of
transformers, mutual inductor winding and others sensitivity, low
resistance.
