DD IEC/TS 61934 is a technical specification for off-line electrical measurement of partial discharges (PD) which occurs in an electrical insulation system.
The electrical insulation system involved in DD IEC/TS 61934 is under stress by the 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 DD IEC/TS 61934 with specific products may require the application of additional procedures.
Note 2 - The procedures described in DD IEC/TS 61934 are emerging technologies. Experience and caution, as well as certain preconditions, are needed to apply it.
DD IEC/TS 61934 on Electrical measurement of partial discharges (PD) is useful for:
Power electronics has developed along with both control theory and semiconductor technology. Switching is one of the essential features of power electronics control. For higher efficiency and smoother operation, switching times of the latest devices such as insulated gate bipolar transistor (IGBT) tend to be shorter than microseconds. The advantage of DD IEC/TS 61934 is that the method used in DD IEC/TS 61934 involves proper insulation of material so as to reduce the chances of loss of capital, life and property.
Using DD IEC/TS 61934 specification can protect the user from any other conductor and electric leakages.
