Product Description
XZH TEST Transformer DC Resistance Tester Resistance Meter
Transformer DC resistance testing is an essential procedure in transformer manufacturing for semi-finished and finished products, as well as for factory tests, installation, overhaul, tap changer adjustments, handover tests, and preventive maintenance in the power sector.
This test helps verify:
- Winding joint welding quality
- Potential short-circuits between winding turns
- Voltage tap switch contact quality
- Alignment between tap changer actual position and indicated position
- Lead wire integrity and potential breaks
The XHZ1010S Transformer DC Resistance Tester features advanced power supply technology, offering compact size, light weight, high output current, excellent repeatability, strong anti-interference capability, and comprehensive protection functions. The instrument is controlled by a high-speed microcontroller with full automation, including automatic discharge and discharge alarm functions.
Key Features:
- High test accuracy with simple operation for rapid transformer DC resistance measurement
- 320×240 dot matrix 65K true color LCD with excellent visibility in strong light
- Built-in power-off storage for 1000 test data sets with instant recall capability
