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 | 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 |
| Vertical Sensitivity | 250V/DIV 500V/DIV, 1000V |
| 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) |
