IEC TS 61934:2011 pdfダウンロード。Electrical insulating materials and systems – Electrical measurement of partial discharges (PD) under short rise time and repetitive voltage impulses 1 Scope IEC/TS 61 934, which is a technical specification, is applicable to the off-line electrical measurement of partial discharges (PD) that occur in electrical insulation systems (EIS) when stressed by repetitive voltage impulses generated from electronic power devices. Typical applications are EIS belonging to apparatus driven by power electronics, such as motors, inductive reactors and windmill generators. NOTE 1 Use of this technical specification with specific products may require the application of additional procedures. NOTE 2...
