Custom LV Power Capacitor Replacement for Wind Farm Application – Australia

A major Australian wind farm operator required a reliable replacement solution for installed LV power capacitors used in wind turbine applications. The objective was to ensure seamless integration, long service life, and optimized performance under demanding operating conditions.

Challenge

Wind turbine environments require:

  • High reliability under continuous load

  • Resistance to thermal and electrical stress

  • Direct-fit mechanical compatibility

  • Long operational lifetime

The client requested a technically equivalent solution with optimized design and installation compatibility.

ISKRA Solution

ISKRA developed and supplied the KNK9053 series heavy-duty LV power capacitors, specifically engineered for wind farm applications.

Key features:

  • Custom-designed mechanical dimensions

  • Optimized terminal arrangement

  • 660/1000V, 50Hz configuration

  • Heavy-duty design for high-load wind turbine operation

  • Designed for long service lifetime

Non-functional casing samples were delivered for on-site installation verification to ensure perfect mechanical compatibility before full rollout.

Results

  • Successful pilot implementation

  • Confirmed installation compatibility

  • Optimized design for wind turbine conditions

  • Strengthened partnership for future renewable projects

This project confirms ISKRA’s capability to deliver custom-engineered power quality solutions for renewable energy applications worldwide.
