Space Charge Measurement Device "Q-PEA"

Sample measurements are also possible! We can accommodate customizations as much as possible, including measurements using a constant temperature bath and changes to sample holds.

The "Q-PEA" is a space charge measurement device that uses the Pulsed Electro Acoustic method (PEA method) to non-destructively and easily measure the distribution of space charges accumulated inside dielectric and insulating materials in real-time. The PEA method involves applying a pulsed voltage between upper and lower electrodes to vibrate the internal space charges, generating pressure waves that are detected by sensors. By observing and analyzing these sensor signals, the distribution, location, and amount of space charges can be understood non-destructively. 【Standard Configuration (Partial)】 ■ Upper Electrode / Lower Electrode ■ Electrical Box (Pulse Generator / 15V Amplifier Power Supply / Analog Unit) ■ Bias Power Supply (HEOPS-10B2-42 High-Speed Type ~1kHz ±10kV ±2mA) ■ Oscilloscope (HDO4034A 350MHz 10GS/s 4ch) ■ Rack *For more details, please refer to the related links or feel free to contact us.
