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.

​

Four Resistance Ranges:

  • 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

​

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.

​

H.V Flash Test Formula:

  • 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 turn-to-turn, coil-to-coil, and phase-to-phase insulation. The test is compared with the stored master waveform. If the %EAR variation exceeds the user-defined limit, the audio/visual alarm is triggered, and the test sequence stops. It can also detect open circuits, grounds, phase reversals, misconnections, and wrong turn counts.

​

Surge Test Formula:

  • 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 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
