scope:
This 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 having a rise time of 50 µs or less.
Typical applications are EIS belonging to apparatus driven by power electronics, such as motors.
NOTE 1 Use of this document with specific products may require specification of additional procedures.
NOTE 2 Those described in the TS are emerging technologies, so that experience and cautions, as well as certain preconditions, are needed to apply this TS.
Excluded are
- methods based on optical or ultrasonic PD detection,
- fields of application for PD measurements when stressed by non-repetitive impulse voltages.
