I. Performance Features

1. The technical performance is completely in line with the technical conditions of the national standard DL/T1093-2008 "Director of the Electric Relics Detection and Judgment of the Transformers Winds Wind Wind by Winding";

2. Use two modes of internal and external power supply. The internal power supply provides 24V and 220V. In order to prevent the short -circuit current from being too large, the 24V gear should be selected for the first test. When the test current is less than 1A, you can choose the 220V gear;

3. Use high -performance embedded processing chips, digital narrow belt filtering and other technologies to effectively suppress industrial frequency and high -frequency interference;

4. Use three -phase wiring to measure the phase, only the low voltage side is needed, and the three phases are connected at one time at a time.

5. The measurement process can be used for manual measurement and automatic measurement. The first test can adopt a manual measurement mode to test the current voltage of the measurement measurement; automatically measures the measurement and calculation automatically;

6. In the measurement process, obtain voltage, current, frequency, effective power, short -circuit impedance, short -circuit electrical resistance, leakage inductance, etc.;

7. Support test data generation printing output;

8. Short -circuit protection to ensure that the instrument is not damaged in the case of short circuit during wiring.
