Dielectric Loss General Tester

HDBS-I transformer loss parameter tester

HDBS-I transformer loss parameter tester

Scope of application

Suitable for no-load and short-circuit loss measurement of power system transformers

Performance characteristics

(1) 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 simultaneously;

(2) Automatically calculate the impedance voltage percentage of the transformer and convert it to the load loss under the rated temperature and rated current;

(3) Single-phase measurement of three-phase transformer: it can be used to check the defects of single-phase transformer or for the situation where there is no three-phase power on site. The instrument can record the data of three single-phase measurements, and can calculate the no-load current, no-load loss, impedance voltage and load loss of the transformer according to the different connections of the transformer;

(4) There are 30kVA-2500kVA amorphous alloys, S11, S9, S7 no-load current percentage, no-load loss, impedance voltage percentage, and load loss specified by the national standard, which can be inquired according to the type of transformer and the capacity of the transformer. ;

(5) It can be directly measured in the allowable measurement range of the instrument. If the measurement range is exceeded, an external voltage and current transformer can be connected. The instrument can set the ratio of the external voltage and current transformer to directly display the value of the applied voltage and current;

(6) The instrument displays the distortion rate of the applied power waveform, automatically calculates the no-load current of the transformer, and converts it to the no-load loss under the rated voltage and has been corrected for waveform distortion;

(7) The built-in memory of the instrument can store 20 groups of data
