StrayAmpMiner®

Patent-pending parallel-passive EM loss recovery system

Converts harmonic, reactive, and I²R losses from stray current into usable power capacity—without touching your utility contract.

Three Pillars of Performance

Efficiency

Recover 5–20% of lost capacity from harmonic and reactive power waste streams

  • • Reduce kWh consumption
  • • Lower demand charges
  • • Improve transformer headroom

Power Quality

Reduce THD, voltage sags, and current peaks for cleaner, more stable power

  • • Lower total harmonic distortion
  • • Reduce neutral-ground voltage
  • • Minimize inrush transients

Sustainability

Carbon-free capacity gains with verified environmental impact

  • • Real-time carbon credit tracking
  • • ESG-ready reporting
  • • No new infrastructure required
