Application:
This tester is widely used for testing newly and rewound motors. It helps in finding and predicting the faults in EV motors before it actually happens. This tester is used in the
motor shop and in field to test the following:
-
EV Slators
SOFTWARE INDICATOR & CONTROLS:
-
Adjustable Volts/Div and TimeBase
-
Colour coded waveform display
-
Surge test peak voltage indicator
-
Graphical and numerical %error display
-
Target voltage indicator based on motor rating
-
Test result lamp indicator
-
Save, recall and print waveforms & reports
Test Specifications:
The Automatic Sequential Analyzer performs the tests in the following sequence, and in case of a fault, it stops the sequence of tests and sets off a buzzer alarm to the user.
I) Resistance Test with Temperature Compensation
The Resistance test detects the variance of resistance values between the phases by applying a constant current to the winding and picking up the potential drop across it. The Resistance value is compensated to either 20°C or 25°C ambient temperature as per the user requirements.
Resistance Range:
-
Range 1: 1.00 – 100.00 mΩ
Test Time:
-
0-10 sec
II) I.R (Megohm) Test
The I.R test checks the strength of the ground wall insulation that can be damaged due to dirt, carbon, moisture, or weak wire insulation.
Test Voltage:
-
500 Volts (DC)
Test Time:
-
0-10 sec
I.R Limit:
-
0-200 MΩ
III) H.V Flash Test
The H.V Flash test checks the strength of the ground wall insulation at a higher applied voltage than the I.R test. If there is a sudden surge in the leakage current, it indicates weak insulation, and the test fails.
Test Voltage:
-
0-2.5KV AC (Adjustable)
Test Time:
-
0-10 sec
Overtrip Leakage Limit:
-
0.1-10 mAmps
IV) Masterless Surge Test
The Automatic Surge test is performed on each phase of the stator to detect turn-to-turn, coil-to-coil, and phase-to-phase insulation. The test is compared with the stored master waveform.
Max Surge Voltage:
-
0 – 3000 Volts (Adjustable)
Max Pulse Current:
-
1000 Amps
Max Pulse Energy:
-
4.5 J
Impulse Rise Time:
-
0.1-0.2 μS
Impulse Repetition Rate:
-
50 Hz
Vertical Sensitivity:
-
250V/DIV, 500V/DIV, 1000V
Sweep/Time Base:
-
10 μS – 10mS
Input Test Voltage Requirements:
-
Operating Voltage: 230V ± 10%
Power Consumption:
-
300W
Weight (full panel):
-
100 kgs (approx)
Physical Dimensions (W x H x D):
-
550 x 1700 x 650 mm
