Transformer Capacity Dissipation Factor tester can test the transformer capacity, type, no load loss, no load current, load loss, impedance voltage, as well as three-phase voltage, effective current value and effective power etc. It is small in volume, light in weight, in high accuracy, with steady property, easy to operation can replace the traditional testers. It is displayed by LCD, operated by menu, with friendly interface, is the first choice for all customers

Main Functions and Features:
1. Output three-phase sine wave inverter power source, in the absence of an external AC power, transformer capacity can be tested and automatically determined.
2. Dual power supply, internal battery-powered instruments and external AC 220V power supply.
3. For Single-phase, three-phase electric arc furnace transformers capacity tests.
4. For dry-type transformer and single-phase transformer tests.
5. For S7, S9, S11, S13, S15, SZ7, SZ9, SZ11, D9, D10, D11, SG8, SG9, SG10, SC8, SC9, SC10 type 10kV,  35 kV transformer tests.
6. Supporting HYG series transformer testing power, measuring three-phase transformer parameters by use of single-phase measurement method for three times.
7. Test the transformer no load loss, no load current, load loss, impedance voltage, as well as three-phase voltage, effective current value and effective power, automatically capture the datas. 
8. Automatic switching range, connecting CT, PT to measure large transformers, direct display all data values.
9. No-load test accurately measuring the parameter settings without the need for voltage calibration.
10. Load test for measuring current drop and automatically converted to the current rated value.
11. Automatically transferring load loss, impedance voltage test datas to 75, 80, 100, 115, 120, 145 ºC.
12. Large-screen LCD interface, character prompt and easy to operate.
13. Automatically determine transformer rated capacity and calculates the deviation.
14. Software calibration feature for automatic voltage, current, power, phase calibration.
15. Real time clock to record the test time.
16. Large storage to record rated parameters, with/without load test results for 170 transformers.
