Electrical insulating materials and systems. Electrical measurement of partial discharges (PD) under short rise time and repetitive voltage impulses1 Scope IEC TS 61934 , 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

Methods for the division of samples in paste or in liquid form have been added

The severity indicated in BS EN 62005-3 for the test by the references are intended for quality evaluation

As the legal regulatory requirements presently differ throughout the world

BS EN 62361-2 contains examples of mapping between IEC power systems information exchange standards

It only considers artificial lighting

The DNA Comet Assay is not radiation specific

These Profiles are therefore not listed above

BS 8103-3 applies to:

Organizations increasingly use benchmarking to compare their performance against that of others in the same industry

Annex A (informative) Cross-references

There are some specific applications where aerospace-grade stainless steel may surpass aluminum in performance

The measured power curve is determined by collecting simultaneous measurements of wind speed and power output at the test site for a period that is long enough to establish a statistically significant database over a range of wind speeds and under varying wind and atmospheric conditions
