Solenoid valve for Lock Test (24 V)
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

Resistance
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.
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.
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
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
