Products Features

KDZR-S20A is a crucial testing item in transformer manufacturing, including semi-finished product testing, finished product factory inspection, installation, handover testing, and preventive testing by power departments. This test effectively detects manufacturing defects such as improper coil material selection, poor welding, loose connections, missing segments, and broken wires, as well as potential issues after operation. To meet the need for rapid measurement of transformer DC resistance, the company has leveraged its technological advantages to develop the ""Transformer Three-Phase DC Resistance Tester''. This instrument features advanced power supply technology and is controlled by a microcontroller, automatically performing self-checks, data processing, display, and printing functions. It also includes automatic discharge and discharge alarm indicators. With its high testing accuracy and user-friendly operation, the device enables quick and efficient DC resistance measurement of transformers.

 

**Product Highlights:** -

**Three-Phase Testing:** For transformers with YN or yn connections on the high-voltage or low-voltage side, **a single connection allows simultaneous three-phase testing** of A0, B0, and C0 DC resistance, and **automatically calculates the three-phase unbalance**, saving testing time. -
**Single-Phase Testing:** **Supports transformers with any connection type**, allowing users to **select any winding for testing** with a single connection. The entire testing process requires no switching of test leads, making it more convenient to operate. -

**Test Matrix Function:** **Built-in test matrix** allows storage of DC resistance values and three-phase unbalance for each tap position, and it can **print the DC resistance values corrected to rated temperature**, providing detailed data records. -

**Clear Display:** **5.7-inch LCD display** that is clearly visible even in sunlight, making it easy to use outdoors. -

**High-Speed Mini Thermal Printer:** **Built-in thermal printer** can **print measurement data and historical data**, making data archiving and review more convenient. -

**Large Data Storage Capacity:** Can store **500 sets of test data** and supports **USB flash drive storage**, making it easy to back up and transfer data. -

**Comprehensive Back EMF Protection:** Features **back EMF protection**, ensuring the safe operation of the equipment. -

**Automatic Discharge and Discharge Alarm Function:** **Automatic discharge** and **discharge alarm indicator** reduce the risk of operator error, ensuring both equipment and personnel safety. -

**Multiple Advantages:** Features **wide temperature range**, **high accuracy**, **shock resistance**, **anti-interference**, and **portability**, making it suitable for testing in various environments.
