KDZC-10A Transformer DC Resistance Tester is an essential testing device for transformers during handover, major maintenance, and after changing the tap switch. Traditionally, using methods such as the bridge method and voltage drop method to measure the DC resistance of transformer windings and high-power inductive devices is time-consuming and labor-intensive. To improve this situation, reduce measurement time, and ease the workload of test personnel, our company has developed a fast DC resistance tester.

The KDZC-10A Transformer DC Resistance Tester is the ideal device for measuring the DC resistance of transformer windings and high-power inductive devices.

The KDZC-10A Transformer DC Resistance Tester features highly automated measurement functions, high precision, a wide measurement range, stable data, good repeatability, strong anti-interference capability, comprehensive protection functions, and fast charging and discharging speeds.

1. Utilizes a high-speed 16-bit A/D converter, ensuring stable measurement data with excellent repeatability.

2. Features an internal rechargeable battery and fast charging circuit, equipped with charging indication and overcharge protection functions.

3. Employs automatic programmable current source technology, allowing manual selection of typical output currents or automatic control by an internal microcontroller. The current source includes 3000 current levels, and in automatic mode, the microcontroller adjusts the output current based on the measured resistance to achieve a broad measurement range and optimal measurement conditions.

4. Provides real-time dynamic display with rapid response speed. During measurement, you can directly switch the tap changer without restarting the instrument; the new resistance value will be quickly displayed, and the instrument will automatically prompt the change.

5. Designed with advanced intelligence, offering cleverly designed features that include automatic detection of faulty test leads (such as loose or broken connections).

6. Comprehensive protection functions safeguard against reverse EMF impacts on the instrument and include an automatic discharge indicator function.

7. Displays the measurement current and measurement time.

8. Can store up to 250 sets of measurement data, which are retained even after power loss.

9. Features a full Chinese menu and operation prompts for intuitive and convenient use.
