3.Applications

TK6800 Transformer Comprehensive Characteristic Tester Calibration Device Applications

☆ No-load or Load Test, Short Circuit Impedance Test

TK6800 Transformer Comprehensive Characteristic Tester Calibration Device Short Circuit Impedance Test

• When calibrating the no-load tester, TK6800 can switch the output transformer rated voltage or 50%~100% rated current, adjust the power output, realize the simulation of no-load and load loss, and calibrate the no-load tester.

• During the load test, the short-circuit impedance value can also be obtained at the same time to complete the calibration of the short-circuit impedance tester. Parameters can be used for transformer capacity calculations.

☆ Capacity Test

TK6800 Transformer Comprehensive Characteristic Tester Calibration Device Capacity Test

• When calibrating the capacity tester, TK6800 selects the corresponding gear according to the resistance value obtained by the short-circuit impedance test. Set the voltage output according to the calibration coefficient and measure the tester output current value. Calculate and determine the transformer capacity value through the obtained short-circuit impedance voltage and actual short-circuit impedance value, and calibrate the capacity tester.
