Identify Power Quality Problems Before They Damage Equipment
Harmonics Analysis in Santa Clarita for facilities experiencing unexplained equipment failures, overheating transformers, or elevated utility bills
Lariat Electric performs harmonics analysis to detect electrical distortion caused by nonlinear loads such as variable frequency drives, LED lighting systems, uninterruptible power supplies, and other electronic equipment that distort the sinusoidal waveform of alternating current. If you manage a facility in Santa Clarita, Palmdale, Burbank, or a surrounding area where sensitive electronics share circuits with high-power machinery, or if transformers run hot despite being sized correctly on paper, harmonic distortion may be degrading system performance and shortening equipment life without presenting obvious symptoms during routine inspections.
Harmonic currents create additional heating in conductors, transformers, and circuit breakers, and they can cause nuisance tripping, capacitor bank failures, and interference with communication systems. Testing involves connecting a power quality analyzer at multiple points in your electrical distribution system to capture voltage and current waveforms over a defined period, then calculating total harmonic distortion percentages and identifying which frequencies are present at problematic levels. Results show whether harmonics exceed IEEE 519 recommended limits and where corrective measures should be applied.
If you have unexplained electrical issues or are planning to add loads that generate harmonics, contact Lariat Electric to schedule testing and receive a detailed analysis of your power quality conditions in Santa Clarita and neighboring communities.
How Testing Works and What the Results Tell You
You will see Lariat Electric install monitoring equipment at your main service entrance, subpanels, and branch circuits feeding suspect loads to capture a complete picture of how harmonics propagate through your facility. Measurements are recorded over several days to account for load variations during different shifts or operational cycles. The analyzer logs voltage and current at high sampling rates, then performs a Fourier transform to break the waveform into individual frequency components and quantify the magnitude of each harmonic order.
After testing, you receive a report that identifies specific harmonic frequencies, their sources, and the degree to which they exceed acceptable thresholds. Lariat Electric explains which equipment is contributing most to the problem and recommends solutions such as installing line reactors, passive filters, active harmonic filters, or redistributing loads to balance phases. Once corrections are implemented, you will notice reduced transformer temperatures, fewer breaker trips, and extended life from motors and other inductive equipment that previously suffered from excess heat and vibration caused by harmonic currents.

The analysis also identifies whether neutral conductors are overloaded due to triplen harmonics, which can create fire hazards in facilities with substantial LED or computer loads. Results are compared against industry standards to determine compliance and guide decisions about system upgrades. This service is particularly valuable before adding large nonlinear loads or when troubleshooting persistent electrical problems that have no clear mechanical or thermal cause.
Questions Facility Managers Ask About Harmonics and Power Quality
Understanding what harmonics are and how they affect daily operations helps you make informed decisions about testing and corrective measures.
What causes harmonic distortion in electrical systems?
Harmonics are generated by equipment that draws current in short pulses rather than smooth sine waves, including variable speed drives, switch-mode power supplies, and electronic ballasts common in modern facilities.
How do harmonics damage equipment?
Harmonic currents increase heating in transformers, motors, and conductors beyond what nameplate ratings predict, leading to insulation breakdown, premature failure, and reduced efficiency over time.
When should harmonics testing be performed?
Testing is recommended when adding significant electronic loads, experiencing unexplained equipment failures, or noticing elevated energy costs that do not correspond to increased production in Santa Clarita facilities.
Why does fixing harmonics reduce utility bills?
Reducing harmonic distortion improves power factor and decreases wasted energy dissipated as heat, which lowers demand charges and kilowatt-hour consumption on your monthly utility statement.
How long does a harmonics analysis take?
Data collection typically runs for three to seven days to capture full operational cycles, with analysis and reporting completed within one week after monitoring equipment is removed from your Santa Clarita facility.
Lariat Electric provides clear documentation of findings and actionable recommendations that address root causes rather than symptoms. If you suspect power quality issues are affecting your operations in Santa Clarita, reach out to schedule harmonics analysis and receive a comprehensive evaluation of your electrical system.
