Pertains 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.

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.

NOTE1 Use of this technical specification with specific products may require the application of additional procedures.

NOTE2 The procedures described in this technical specification are emerging technologies. Experience and caution, as well as certain preconditions, are needed to apply it.

Excluded from the scope of this technical specification are

  • methods based on optical or ultrasonic PD detection,

  • fields of application for PD measurements when stressed by non-repetitive impulse voltages such as lightning impulse or switching impulses from switchgear.
