Pump Test - Requirement

• No Load Test
• High Voltage Test
• Insulation resistance Measured with 500V DC
• On Load Test
• Lock Rotor Test
• CALCULATED PERFORMANCE AT ACTUAL FREQUENCY
• Flow
• Head
• Pressure
• Efficiency

Pump Test - Parameters Measured3 Phase 0.5HP to
300 HP 1 Phase 0.5HP to 003 HP

• Voltage
• Current
• Resistance
• Frequency
• RPM
• Pressure

4
Pump Test - Parameters Controlled

• Solenoid valve for Lock Test (24 V)

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 1000 v
• For single phase
• 140V 160 V 180 V
• 200V 220V 230 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
