Distinguishing Key Features:
1. Comprehensive 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 motor windings.
3. Insulation Resistance: Accurately test insulation resistance between the phase wire and the motor casing.
4. Inter-turn Test: Identify inter-turn and inter-layer short circuits, poor insulation, and coil deviations in motors or transformers.
5. Withstand Voltage Test: Evaluate the withstand voltage leakage current between the stator winding and the casing. Programmed control ensures precise voltage regulation, which can be managed via computer.
6. No-load Test: Measure vital parameters such as voltage, current, power, power factor, and frequency in no-load conditions for both single and three-phase motors.
7. Stall Rotor Test: Assess voltage, current, power, power factor, and frequency during the motor's stall rotor phase (instantaneous start) for single and three-phase motors.
8. Power Supply: Operates on AC220V±15%, 50Hz±2 Hz, ensuring system stability.
9. Operating Environment: Optimal working temperature ranges from 0 to 40°C.
10. Humidity Tolerance: Suitable for environments with humidity levels up to 70%.
11. Seamless Testing: Complete all tests with the initial wiring setup.
12. Intelligent Control: All testing processes are managed by a sophisticated microcomputer system.
