TEST SPECIFICATIONS

The Automatic Sequential Analyzer performs the tests in the following sequence & in case of a fault; it stops the sequence of tests & 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 25C ambient temperature as per the user requirements.

Four Resistance Range
Range 1 0.001 – 1.999 Ohms
Range 2 0.01 – 19.99 Ohms
Range 3 0.1 – 199.9 Ohms
Range 4 0 – 1999 Ohms
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 once again checks the strength of the ground wall insulation but at a higher applied voltage than the I.R test. If there is sudden surge in the leakage current it indicates that the ground wall insulation is weak and the test has failed.

H.V Flash test = (2×E + 1000) where E is the operating voltage

Test Voltage 0-2.5KV AC (Adjustable)
Test Time 0-10 sec
Overtrip Leakage Current Limit 0.1-10 mAmps

IV) Masterless Surge Test

The Automatic Surge test is performed on each phase of the stator to detect the turn-to-turn, coil-to-coil and phase-to-phase insulation and compared with the stored master waveform. If the %EAR variation is over the limit set by the user then the audio/visual alarm is set off to notify the operator about the failure and test sequence is stopped. It can also detect open circuits, grounds, phase reversals, misconnections and wrong turn counts.

Surge test = √2 × (2×E + 1000) where E is the operating voltage

Max Surge Voltage     0 – 5000 Volts (Adjustable)
Max Pulse Current 330 Amps
Max Pulse Energy 1.0 J
Impulse Rise Time 0.1-0.2 μS (In accordance with IEEE 522 standard)
Impulse Repetition Rate 50 Hz (50 Pulses per second)
Vertical Sensitivity 250V/DIV 500V/DIV, 1000V/DIV
Sweep/Time base 10 uS – 10mS
Input Test Voltage Requirements
Operating Voltage 230V ± 10%
Power Consumption 300W
Weight (full panel) 100kgs (approx)
Physical Dimensions (W X H X D) 550 X 1700 X 650 (mm)
