Study on reliability of vacuum interrupter (VI) such as detection method of the slow leak has been extensively carried out, while study on discharge properties in low vacuum of VI is still insufficient. In this report, we experimentally investigated discharge properties inside VI under closed contact and open contact conditions of main contactors in low vacuum of VI to simulate vacuum leakage. We also measured current waveforms and spectrum of electromagnetic wave (EMW) emitted by discharges in VI. Furthermore, we discussed the relationship between partial discharge against the product of pressure and gap spacing, and compared the results with the Paschens curve of air. We also discussed flowing path of the discharge current in an experimental circuit including VI.
