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 1.00 – 100.00 m.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.

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 the turn-to-turn, coil-to-coil and phase-to-phase insulation and 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
