Impulse Winding Tester ST4030A

Impulse Winding Tester ST4030A

The inspection of motor windings is changing. From one-turn shorts to detecting defects in the rotor assembly state!

The applied voltage has been increased to a maximum of 4200V, and the ST4030 has been reborn as the ST4030A! ● By quantifying the response waveform, a one-turn short can be identified. ● Impulse testing is possible in the rotor assembly state with judgment based on LC and RC values. ● The discharge detection function (optional) accurately detects pseudo-shorts. ● Captures subtle changes in the waveform without missing them, with high-speed sampling × high resolution × long waveform. ● Reduces variation in applied voltage, achieving high accuracy in defective product detection. ● Also supports insulation breakdown voltage testing (BDV) as required by standards.

Impulse Winding Tester IWT-5000A

Impulse Winding Tester IWT-5000A

Impulse Winding Tester IWT-5000A

The Impulse Winding Tester "IWT-5000A" applies pulse voltages up to 5000V to coils such as inverters and motors, allowing for testing of coil disconnections, shorts, insulation failures, and changes in inductance. By providing narrow (low energy) pulse voltages in the range of 200 to 5000V, the damage inflicted on the tested coil is minimized. It is equipped with an automatic scaling function for measurements and has four types of automatic judgment functions for inspecting insulation failures such as corona discharge. "Main Specifications" ■ Applied Voltage: 200–5000V ■ Applied Energy: Maximum 0.25J ■ Inductance Testing Range: 0.2μH and above ■ Sampling Speed: 8bit/10ns (100MHz) ■ Sampling Memory: 5000Byte ■ Input Impedance: 10MΩ ■ Screen: Color TFC-LCD 5.6 inches 320x234 ■ PC Link Interface: 1. USB2.0 2. RS-232 3. I/O ■ Equipped with four types of automatic judgment methods

Impulse Winding Tester [Partial Discharge Testing Possible! ST-6K]

Impulse Winding Tester [Partial Discharge Testing Possible! ST-6K]

Using high-speed sampling technology, it is possible to save the waveforms of the standard/master coil and the DUT (Device Under Test) in the measuring instrument. Partial discharge testing is possible!

The Impulse Winding Tester ST-6K is an essential device for testing winding products such as transformers, motors, rotors, stators, electric valves, generators, and all types of coils. It provides an ideal testing method for detecting insulation failures and uses high-speed sampling technology to save the waveforms of standard/master coils and the DUT (Device Under Test) in the measuring instrument. By comparing the waveforms of the master and the DUT, it is easy to identify the parts without issues. Furthermore, it can display the ideal coil waveform as a master and calculate the inductance values of partial discharges, making the ST-6K particularly effective for production and quality control.

Impulse winding tester "DWX series"

Impulse winding tester "DWX series"

The definitive version of low inductance coil testing! The waveform of the 10μH coil is displayed clearly!

The "DWX Series" is a testing machine designed to accommodate various inductance and coil tests in response to the miniaturization and high frequency of coil components. By incorporating a high-speed switch impulse power supply and a high-speed A/D sampling circuit, it has become possible to test low inductance coils, which were previously considered difficult. It can obtain a faithful sine waveform without waveform distortion, and the waveform judgment capability and discharge detection sensitivity have been improved. 【Features】 ■ Enables testing of low inductance coils that were previously considered difficult ■ Improved waveform fidelity and discharge detection sensitivity through resistive voltage division ■ Achieves high sensitivity and high precision testing with high-speed 100MHz, 8K point sampling ■ Utilizes a Laplacian algorithm for discharge quantity inspection, with clear window display ■ Standard equipped with CompactFlash memory card slot *For more details, please refer to the PDF materials or feel free to contact us.
