PD IEC TS 60034‑27‑5 on Off-line measurement of partial discharge inception voltage is applicable for:
- Manufactures and suppliers of electrical machine/circuit device
- Retailers and dealers of electrical machine/circuit device
- Electronic/Mechanical appliance manufactures
Why should you use PD IEC TS 60034‑27‑5?
Partial Discharge is localized electrical discharge that only partially bridges the insulation between conductors and which can or cannot occur adjacent to a conductor. The latest developments in power electronics sector have led to various power drive system (PDS) of variable-speed rotating electrical machines.
PD IEC TS 60034‑27‑5 points out that electrical insulation of machine winding is exposed to numerous voltage impulses due to the repetitive fast switching of power devices in PDS. This helps you understand that the severity of the impulses depends on ratings of converter and machines, converter topology, length of cable between machine and converter, filtering equipment and so on. Thus, you can apply the right measures to reduce them and enhance the durability and proper functioning of the electrical machines.
PD IEC TS 60034‑27‑5 specifies for you technical concepts such as partial discharge, repetitive partial discharge inception voltage (RPDIV), and repetitive partial discharge extinction voltage (RPDEV), which helps you in measuring off-line partial discharge inception voltage on winding insulation under repetitive impulse voltage. so that you apply the right measures to reduce them and enhance the durability and proper functioning of the electrical machines.
