SDT-06

It is a well-known fact that the surge or impulse voltage test is one of the most effective methods for testing coil windings. When used properly, the Surge Tester is non-destructive and accurately detects winding faults by comparing the waveforms of a test winding with that of a known standard.

Features

• 10-bit A/C Converter is adopted. High resolution provides extremely precise testing.
• Improved basic performances of impulse tester (such as signal-to-noise ratio, frequency characteristic, etc.) enabled more detailed Partial Discharge noise detection.
• Base line fluctuation of AC or DC coupling due to the temperature change is controlled by the auto zero adjustment; as a result, precision of PASS/FAIL detection has improved. The auto zero adjustment is essential for materializing 10-bit voltage resolution tester.
• Estimation of the inductance of master coil can be performed. Because the estimation is calculated by using high voltage, the estimated value may be different from the value of an LCR meter.
• 225 types of master waveform can be stored in the main memory. Also, master waveforms and test waveforms can be displayed on PC.
• Statistical data such as percent defective, variance, etc. can be displayed in graph.
• This tester can be remote-controlled on PC.

Configuration Setting for date, baud rate, firmware update, and buzzar ON/OFF.	Step Voltage Step Voltage Function provides 4-step voltage going up test, and 5 dif- ferent decay waveforms will be displayed on the screen.	Auto Sweep Set Sweep range can be set automatically by pressing Auto key.	Voltage Calibration Pressing Learn key after voltage setting makes voltage calibration.
Estimation of L Estimate L can be calculated by setting zone on the first resonance.	Master Data Store 225 master data can be stored in the main memory.	PASS in Auto Mode PASS/FAIL detection in the Auto Mode.	FAIL in Auto Mode PASS/FAIL detection in the Auto Mode. "Fail" due to "One Turn Short".
Graphical display Test results will be tallied and displayed in graph.	PASS in Auto Mode PASS/FAIL detection in the Auto Mode.	FAIL in Auto Mode PASS/FAIL detection in the Auto Mode. "Fail" due to "Discharge".	Step Voltage Inraising voltage from 1.4kV　to the higher value by 80-volt steps, discharge can be observed at 1720V.
