HZ-3150A Transformer Winding Resistance Measurement Kit 50a
Transformer DC resistance tester is a device used to measure the DC resistance of transformer coils. It has high precision and reliability, and can measure various types of transformers, including dry-type transformers, oil immersed transformers, etc.
The main parts of the tester include the source and detection parts. The source part provides a certain voltage and current to excite the transformer coil to generate current, while the detection part consists of high-precision voltage, current, and time measurements to measure the resistance value of the transformer coil.
The tester is easy to operate and can analyze measurement data through an intuitive digital display and graphical interface. It can also perform automatic or manual calibration and data storage. By using a transformer DC resistance tester, the quality and safety performance of transformers can be effectively detected and evaluated.
Configuration
1. The device output current high, light weight.
2. Has a complete circuit protection, reliable.
3. Vertical chassis structure, easy operating on field.
4. Discharge alarm, discharge indicator clear, reduces misuse.
