IEC/TS 61934 is a technical specification that applies to the offline electrical measurement of partial discharges (PD) in electrical insulation systems (EIS) when stressed by repetitive voltage impulses generated from electronic power devices.
Typical applications include EIS driven by power electronics, such as motors, inductive reactors, and windmill generators.
Note 1: The use of this technical specification with specific products may require the application of additional procedures.
Note 2: The procedures described in this technical specification are emerging technologies. Experience and caution, as well as certain preconditions, are needed to apply them.
Excluded from the scope of this technical specification are:
- Methods based on optical or ultrasonic PD detection,
- Applications for PD measurements when stressed by non-repetitive impulse voltages such as lightning impulses or switching impulses from switchgear.
