PD measurements on capacitors are intended to detect potential defects in the insulation in order to prevent future failures, as partial discharges may weaken the insulation to the housing and within the dielectric.
The procedures for PD measurements are described in various IEC standards. However, especially with regard to the testing of capacitors, there may be limitations and misinterpretations regarding the informative value of such tests. This common guideline by the capacitor manufacturers organized in the ZVEI intends to prevent such misunderstandings.

Statement of the ZVEI-Power Capacitors Division on VDE-AR-N 4110: Technical rules for the connection of customer systems and their operation. Harmonics at the MV network connection (available in German language only)

Power capacitors are electrical energy storage devices which must always be handled with caution. In error situations they can cause serious injuries or damage to persons and adjacent equipment. This document was developed jointly by Germany’s capacitor manufacturers to promote understanding of the risks and how to deal with them.

In industrial and public grids, the growing variety of power electronic energy converters with their highly non-linear current characteristics will increasingly compromise power quality, especially in the low- and medium-voltage distribution grids. This guide by the ZVEI Power Capacitors Division explains how power quality is influenced and what the causes and effects are, and presents technical approaches to reduce the respective causes of a negative influence on power quality.
