Four main features of the product
- Two tests required for coil testing in one unit
- With a single unit, you can perform high-level tests for rare shorts in coils and partial discharges caused by insulation defects in coils, with simple operation.
- Visualization of inspection process by database management
- Master waveform, Determination conditions, Test results( Save the test waveform and the judgment value ) in the built-in database.
You can browse remotely from a computer using SQL client software.
In addition, test results can be searched by pass or fail, by date and time, which is useful for analysis such as NG generation rate.
- Abundant Additional Options
- PD (Partial Discharge) detection antenna / 3ch+GND built-in switching circuit / 4-terminal measurement circuit / Additional applied energy / Current measurement, and many other additional functions are available. (*Some functions cannot be installed at the same time.)
- Pleasant Functions
- 10.1-inch color TFT LCD touch panel for improved operability External memory (USB, SD) storage of screen shots Creation of master waveforms by [Averaging / Composite / Test Waveforms

With the spread of inverter motors, partial discharge testing is required to test the insulation reliability of coils, as well as home appliances.
Partial Discharge TesterRepeated Impulse Surge Power Supply
IPX-05BP
IPX-05BP is a power supply that can output repeated impulse voltages from low frequency to high frequency for the evaluation of surge resistant wires and nano-composite wires used for EV motors. Repeated impulse voltages simulating inverter surges can be applied to the sample continuously for a long time. The system can be used for evaluation tests of capacitive or inductive loads ranging from small to large capacitance.
Comprehensive testing machinesAutomatic stator coil testing machine
This is an automatic coil testing machine based on over 50 years of experience in coil testing.
Each testing device is centrally controlled by PC or PLC, etc., and all tests are performed automatically. It is also possible to switch circuits by manual operation for individual testing.
As a custom-made product, we can also manufacture a test stand that matches the shape of the customer's workpiece. Combining these products improves workability and safety.
Registration of judgment criteria, individual tests, etc. can also all be operated from the screen.
