Harmonic Filters
Harmonic Filters
As buildings become more dependent on variable frequency drives, LED lighting, and electronic equipment, electrical harmonics can reduce system performance and damage critical equipment.
Smart Space installs harmonic filters to improve power quality, enhance system reliability, and help protect your investment.
What Are Harmonics?
Utility power is designed to operate at a smooth 60 Hz sine wave. Modern electronic equipment draws electricity in pulses instead of smooth waves. These pulses create harmonic currents. Harmonics circulate through the electrical system without performing useful work. The result is increased energy consumption and unnecessary heat.
Common Sources of Harmonic Distortion & Signs Your Building May Have Harmonic Problems.
Common Sources of Harmonic Distortion
- Variable Frequency Drives (VFDs)
- LED Lighting
- HVAC Equipment
- Escalators & Elevators
- Data Centers
- Computer Equipment
- Battery Chargers
- EV Charging Stations
- UPS Systems
- Manufacturing Equipment
- Airports
- Hospitals
- Universities
Signs Your Building May Have Harmonic Problems
Many facilities experience harmonic distortion without realizing it.
Common symptoms include:
- Hot electrical panels
- Overheated neutral conductors
- Frequent breaker trips
- Transformer overheating
- Motor failures
- Unexplained equipment failures
- Reduced equipment life
- High electrical consumption
- Excessive electrical noise
- Flickering lights
Why Harmonics Cost Money
Costly Longterm Impacts:
-
Increased Energy Consumption-Harmonic currents circulate through conductors and transformers as heat instead of useful work.
-
Overheated Transformers-Heat accelerates insulation breakdown and reduces transformer life.
- Pverloaded Neutral Conductors-Triplen harmonics accumulate on the neutral conductor instead of canceling.
- Reduced Equipment Life-Motors, drives, UPS systems, and electronics operate under higher thermal stress.
- Increased Maintenance Costs-Premature equipment failures create unnecessary repair expenses and downtime.
Our Process
Assess
Evaluate existing lighting, controls, HVAC operation, equipment, schedules, and building use.
Analyze
Identify operational inefficiencies, energy-saving opportunities, and areas where systems can work together more effectively.
Recommend
Develop practical recommendations based on your building's needs, operating conditions, and investment objectives.
Implement
Install and/or coordinate upgrades, controls optimization, lighting improvements, and other recommended measures.
Verify
Review system performance and confirm that implemented improvements are operating as intended.

Does installation require shutting off power?
In many cases, Passive Harmonic Filters can be installed while electrical panels remain energized, minimizing operational disruption.
Does the filter require maintenance?
No. The passive design contains no moving parts, software, or controls and operates continuously without maintenance.
How are savings verified?
Savings can be verified through power quality testing, revenue-grade electrical metering, utility bill analysis, and industry-standard. Measurement & Verification (M&V) methodologies such as IPMVP.
Can this be combined with other energy efficiency upgrades?
Yes. Harmonic filtering works well alongside HVAC optimization, LED lighting, building automation improvements, and solar photovoltaic (PV) systems as part of a comprehensive energy management strategy.
