High Voltage Insulation Reliability Evaluation Device "HVUα Series"
High-speed detection circuits with a few tens of nsec installed in all channels! Tester capable of low-noise measurement.
The "HVUα Series" is a high-voltage insulation reliability evaluation device manufactured by J-RAS Corporation. It is equipped with high-speed detection circuits capable of operating in the tens of nanoseconds across all channels, enabling more advanced reliability testing. It can detect partial discharge with a high-speed event measurement function of less than 100 nanoseconds. Each channel has its own power supply and individual control, allowing for different applied voltage settings across all channels. There are no mechanical relay scans, so there are no failures or troubles during continuous testing. Active guarding with triaxial cables enables low-noise measurements. 【Features】 ■ Detects partial discharge with a high-speed event measurement function of less than 100 nanoseconds ■ Each channel has its own power supply and individual feedback for stable voltage application to each sample ■ Individual short-circuit detection circuits for each channel can respond to instantaneous sample short circuits ■ Dedicated software allows for graph display and data recording ■ The system can be configured in units of five channels according to demand *For more details, please refer to the PDF document or feel free to contact us.
