How an Active Harmonic Filter Installation Solved Network Instability Problems
Summary
After commissioning a new HV/LV substation, a North Wales manufacturer experienced instability and tripping. We identified harmonics from VSDs as the root cause and installed Active Harmonic Filters to stabilise the system.
Client Background
A large manufacturing site in North Wales struggling with electrical system instability following substation expansion.
Problem
High harmonic distortion from VSDs caused spurious tripping and overheating of electrical systems.
Solution
A power quality survey confirmed the issue, and we installed Active Harmonic Filters to bring the harmonic levels under control.
Results
  • Network instability eliminated
  • Equipment protection improved
  • Annual maintenance strategy in place
