Model 9005ASA

9005ASA Automatic Sequential Analyzer is the most comprehensive tester designed to automatically check the quality of 1φ & 3φ wound stators in fast paced production motor shops. The tests are performed in the sequential order with the help of user-defined test times and limits.
The Analyzer accurately detects the faults in the stator and audio/visual alarm indicates the type of fault to the operator. This Analyzer has been widely appreciated by the stator manufacturers in India who have to meet tight deadlines to deliver large number of quality stators to their clients.

APPLICATIONS

1φ & 3φ stators

BENEFITS

User friendly front panel controls

User defined limits and test times

Auto/Manual test mode option

Dual station jig to eliminate the loading time of stator and also safeguards the operator from high voltages stressed on the stator

Proximity switch mounted on the jig to automatically start the test cycle

Fast, accurate and completes one test cycle in 12 seconds

Audio/Visual alarm indication for the operator

ACCESSORIES

A Double Station Test Jig Fixture

Housed in dust free enclosure

Servo Stabilizer (Optional)

In house Air conditioner (Optional)

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
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.

For 1φ windings - Resistance test of Main and Aux winding

For 3φ windings - Resistance test of U,V and W winding

10 channel preset limit programmer to set the limits

Three Selectable Resistance Range
Range1	0-19.99Ω
Range2	0-199.9Ω
Range3	0-1999.9Ω
Display	3½ Digits LED Display
Test Time	0-10 sec (adjustable)

II) Rotation Test
The Rotation detection test is useful in cases of stators. It uses die-cast rotors to check the direction of winding i.e. clockwise or counter-clockwise.

III) I.R (Megohm) Test
The IR test checks the strength of the ground wall insulation of the appliance that can be damaged due to dirt, carbon, moisture or weak wire insulation.

Display	3½ Digits LED Display
Test Voltage	500V (DC)
Test Time	0-10 sec
Limit	0-200 MΩ

IV) H.V Flash Test
The H.V Flash test once again checks the strength of the ground wall insulation of the appliance 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
Display	3½ Digits LED Display
Test Time	0-10 sec
OverTrip Leakage Current
Leakage Current Limit	0.1-10mA
Display	3½ Digits LED Display

V) Surge Comparison 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 master stator. If the % 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.
Applied Surge Test Voltage = √2 × (2×E + 1000) where E is the operating voltage
