Transformer DC Winding Resistance Tester High Precision Resistance Measuring Equipment
The Transformer DC Resistance Tester is essential testing equipment for transformer factories, power bureaus and electrical maintenance teams. It is widely used for factory inspection, installation handover test and regular preventive test of transformers to detect winding manufacturing defects and hidden operation faults.
This tester supports six output currents up to 10A with auto current switching, covering a wide resistance range of 500μΩ to 50kΩ. It comes with temperature conversion, multi-protection circuit, large color LCD, data storage and external printing function, realizing efficient and accurate winding DC resistance measurement.
- Six selectable output currents with max 10A output, automatic gear switching for fast operation
- Wide measuring range: 500μΩ ~ 50kΩ, high precision with 0.1μΩ ultra-high resolution
- Built-in resistance temperature conversion function for standard result calculation
- Multiple safety protections: back-EMF protection, disconnection protection, power-off protection, overheating alarm
- 5.6-inch industrial high-brightness color LCD, clear reading under strong sunlight
- Support external printer to output test reports quickly
- Dual storage design: local built-in storage + USB data export storage
