VFDs & Harmonic Analysis / Mitigation
Variable frequency drives on chillers, pumps, thrusters and stabilizers inject harmonics that make lights flicker and equipment misbehave. We install and configure drives (Schneider, ABB) and carry out harmonic analysis and mitigation to clean the system up.

What's included
Prism Marine Electric provides vfds & harmonic analysis / mitigation for yachts, superyachts and sportfish vessels in Fort Lauderdale and throughout Broward, Palm Beach and Miami-Dade County — dockside, at anchor or during a yard period. Licensed, insured and available 24/7, with worldwide travel for vessels under our care.
- VFD installation, replacement and parameter configuration
- Schneider and ABB drive support
- Harmonic analysis and power quality measurement
- Harmonic filter, reactor and mitigation solutions
- Shielded motor cable and correct EMC glanding
- Drive fault diagnosis and thermal management
Our method
We measure before we prescribe: power quality logging at the switchboard shows which drive is distorting the supply and how badly, then we design a mitigation solution — filtering, reactors, cabling or configuration changes — and prove the improvement by re-measuring.
Drives are installed with shielded motor cable, correct earthing and glanding, and cooling that survives a hot machinery space, so faults don't return next season.
Signs it's time to call
- Lights flickering when a drive or chiller runs
- Drives faulting on overcurrent or overvoltage
- Transformers or panels running unusually hot
- Sensitive equipment misbehaving under load
