Coil equipment Tester

HDBR-II Transformer Capacity Tester

Scope of application

Suitable for capacity measurement of distribution power transformers

Performance characteristics

(1) The instrument has a built-in rechargeable battery that can output a three-phase sine wave inverter power supply. It can measure the capacity of the distribution transformer and determine the model without any external power supply. It also displays the impedance voltage of the transformer and converts it to the rated temperature and rated current. Load loss

(2) Three-phase voltage, three-phase current, three-phase power, three-phase average voltage, average current, three-phase total power and related data can be displayed on the same screen;

(3) The instrument is equipped with an RS232 interface, which can communicate with a computer through a data line;

(4) Built-in memory, the instrument can store 20 groups of data;
