Power Quality & Harmonics Study
Protect sensitive electronic automation, CNCs, and drive systems from destructive harmonics, nuisance tripping, voltage fluctuations, and unpredicted production outages.
Clean Power for Demanding Industrial Operations
Modern manufacturing facilities rely heavily on non-linear loads: Variable Frequency Drives (VFDs), UPS systems, induction furnaces, and robotic automation. While these systems drive productivity, they inject dangerous harmonic currents back into your electrical distribution network.
The symptoms are costly: neutral conductor overheating, transformer derating, capacitor bank rupture, PLC latch-ups, and utility penalties for low power factor. HELM Energy Solutions delivers comprehensive Class A power quality diagnostics to pinpoint the root causes and implement definitive engineered filtering.
Complete Power Grid Health Diagnostics
Harmonics Distortion (THD)
Detailed FFT spectral analysis up to the 50th harmonic order (THD-V and THD-I) across main incomers, transformers, and branch sub-panels.
Voltage Sags, Swells & Flicker
High-speed cycle-by-cycle capture of grid disturbances, utility switching surges, and heavy motor starting transients causing breaker trips.
True Power Factor (PF & DPF)
Displacement vs. Distortion Power Factor measurement preventing utility penalty surcharges and optimizing transformer kVA capacity.
Unbalance & Neutral Current
Negative sequence and zero sequence voltage/current unbalance checks preventing excessive 3-phase motor heating and neutral conductor stress.
From Diagnostic Logging to Filter Engineering
Instrumentation Setup & Baseline
Installation of calibrated IEC 61000-4-30 Class A power quality analyzers at points of common coupling (PCC) and major non-linear load feeders.
Continuous Real-Time Logging (7–14 Days)
Capturing true RMS voltage, current, waveforms, transient spikes, and harmonic spectra across peak shifts, idle hours, and changeovers.
Computational Simulation & Root-Cause
Engineering analysis using power system modeling software to check harmonic resonance risks, capacitor bank health, and utility compliance.
Custom Mitigation & Filter Sizing
Turnkey specifications for Active Harmonic Filters (AHF), tuned detuned reactor capacitor banks, isolation transformers, and voltage conditioning.
