5. Pump Test – No Load Test
No load tests could be done at the various voltages starting from 150V to 450V. The system would be programmed to carry out the tests at the following voltages.
For three phase:
150V 200V 250V
300V 350V 400V
415V 450V v
For single phase
140V V 180 V
200V 220V V

6. Pump Test – No Load Test
The following parameters would be recorded and tabulated
Voltage
Current
Power
Frequency
CW RPM
CCW RPM
Slip
Resistance

7. Pump Test – High Voltage Test
High voltage test would be carried out by connecting 1500V AC across the coils and motor body. The leakage current in mA would be recorded. An indicator light will glow to indicate if the leakage current is at acceptable levels. If the current exceeds the limit another light will glow indicating failure.

8. Pump Test – Insulation resistance – Measured with 500V DC
The insulation resistance in mega ohms would be determined by applying 500V DC across the coils and the motor body. The resistance in mega ohms will be recorded
An indicator light will glow to indicate if the resistance is at acceptable levels. If the resistance is less than the limit another light will glow indicating failure.

9. Pump Test – Locked Rotor test
The following parameters will be recorded in locked rotor condition. The rotor would be physically locked during this test.
Voltage
Current
Power

10. Pump Test – On Load test
Load test will be done by varying the flow rate with the help of motorized valve. Tabulated readings as well as graphical display of various parameters Vs flow rate will be provided. The following parameters would be measured and displayed graphically as and when required to be viewed
Current Vs Flow rate
Power Vs Flow rate
Efficiency Vs Flow rate
Pressure Vs Flow rate
