A digital winding resistance meter precisely measures the resistance of transformer windings to assess their condition and detect faults. Chinese manufacturers like Wrindu supply custom, OEM, and wholesale digital meters known for accuracy and durability, helping factories and utilities maintain transformer safety and efficiency worldwide.
What Is a Digital Winding Resistance Meter?
A digital winding resistance meter is a specialized instrument designed to measure the electrical resistance of transformer windings and other inductive components with high precision. It helps identify winding faults such as short-circuits, loose connections, or deterioration.
This tool is essential for transformer manufacturing, maintenance, diagnostics, and quality assurance.
How Does a Digital Winding Resistance Meter Work?
The meter injects a DC current into the winding and measures the voltage drop. Using Ohm’s law, it calculates resistance accurately, often compensating for temperature and environmental factors. The results help evaluate winding integrity.
Wrindu’s advanced meters integrate microprocessor control, digital displays, and data storage for efficient field or factory use.
