KDBR-CZ distribution transformer copper-aluminum material discrimination tester (touch screen version) is a new generation of intelligent detection equipment developed by our company based on the comprehensive upgrading of the original transformer capacity tester. On the basis of inheriting the advantages of the original model, such as small size, easy operation and portability, this product further optimizes the internal core hardware - equipped with a high-performance processor, a more accurate data acquisition system, and updates the latest national standard database, significantly improving the test accuracy and scope of application.

The instrument integrates multiple functions, can efficiently complete the capacity measurement, no-load loss and load loss test of distribution transformer, and accurately determine the material (copper or aluminum) of transformer winding and its energy efficiency code level. Built-in large-capacity high-efficient rechargeable battery can continuously test more than 100 transformers once fully charged, without external power supply, greatly improving the flexibility and efficiency of field operation.

Especially, the built-in three-phase precision 50Hz sine wave AC test power supply of the instrument eliminates the need for additional voltage regulator, current booster or external three-phase power supply and other auxiliary equipment during capacity and load loss test, truly realizing "one machine at hand, no worries". KDBR-CZ is the ideal choice for power operation and maintenance, quality inspection units and transformer manufacturers to carry out on-site fast detection and material identification.
 

This product has many advantages such as small size, light weight, high measurement accuracy, good stability and simple operation. It can completely replace the previous method of measuring transformer loss and capacity with multi-meter method. The wiring is simpler, the testing and recording are more convenient, and your work efficiency is greatly improved.
