Key features:
1. Test items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, no-load test, blocked rotor test.
2. DC resistance: Precisely measure the resistance of the motor winding resistance.
3. Insulation resistance: Accurately test the insulation resistance between the phase wire and the shell.
4. Inter-turn test: Detect inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance issues in motor or transformer coils.
5. Withstand voltage test: Evaluate withstand voltage leakage current between the stator winding and the shell. Program control and computer regulation ensure precise voltage control.
6. No-load test: Measure the voltage, current, power, power factor, and frequency of the motor under no-load conditions (applicable to both single and three-phase).
7. Stall rotor test: Assess voltage, current, power, power factor, and frequency during motor stall rotor (instantaneous start), suitable for both single and three-phase motors.
8. Power supply: AC220V±15%, 50Hz±2 Hz (system working power supply).
9. Operating environment: Stable performance at working temperatures between 0~40 °C.
10. Working humidity: Efficient operation at humidity levels ≤70%.
11. Complete all tests with a single wiring setup.
12. Microcomputer-controlled testing processes for ultimate accuracy and efficiency.
