XHZ1010
The XHZ1010 DC Resistance Tester is essential for all critical
stages of transformer lifecycle testing: from factory checks of
semi-finished/finished products, to installation, overhaul, tap
changer adjustments, handover, and preventive testing by power
sectors. It performs vital diagnostic tasks: assessing winding
joint weld quality, spotting inter-turn short circuits, ensuring
voltage tap changers make secure contact at every position (and
that actual vs. indicated positions match), checking for lead wire
breakage, and detecting broken strands in multi-strand windings.
Designed to meet the demand for fast transformer DC resistance
testing, our XX10A DC Resistance Tester integrates state-of-the-art
power supply technology. It stands out with its compact size, light
weight, high output current, consistent performance, strong
anti-interference ability, and full protective features. Powered by
a high-speed MCU, it offers seamless automation—including automatic
discharge and alarm functions to prevent hazards. Boasting high
accuracy and simple operation, the XX10A streamlines rapid DC
resistance measurement for transformers, making it a go-to solution
for power industry professionals.
Performance Features
1. The instrument can be controlled via Android phones or tablets.
Follow the WeChat official account, download the dedicated APP, and
control the instrument throughout the process. Test data is stored
and uploaded for easy retrieval.
2. The instrument has a maximum output voltage of 24V, facilitating
the selection of larger test currents for high resistance values
and improving testing speed.
3. The instrument adopts new power supply technology, offering
multiple current ranges and a wide measurement range. It can
automatically select the current according to the load, making it
suitable for DC resistance measurement of small and medium-sized
transformers and voltage transformers.
4. It features multiple protection functions, including back EMF
impact, wire breakage and power failure during testing, and power
overheating protection. It reliably protects against back EMF
impacts and provides a simultaneous audible alarm.
5. It has an arbitrary temperature conversion function for copper
and aluminum materials, allowing touch input of any winding
temperature and conversion temperature.
6. Intelligent power management technology ensures the instrument
always operates at minimum power, effectively saving energy and
reducing heat generation.
7. A 7-inch high-brightness touchscreen color LCD provides clear
display even in strong light, full touchscreen operation, and free
switching between Chinese and English.
8. The instrument features a built-in perpetual calendar clock and
power-off memory, capable of storing 1000 sets of test data for
easy access.
9. The instrument has Bluetooth, RS232, and USB interfaces for
computer communication and USB flash drive data storage.
10. It includes a built-in panel-mounted mini printer, allowing for
Chinese-language printing of measurement results.
