What is Why you need to eliminate harmonics in your electrical systems:
Harmonics are a type of electrical pollution which results in distorted voltage and current wave forms. This negatively impacts your electrical systems by increasing the root mean square (RMS) of the voltage and current, lowering the power factor and deteriorating the quality of the electrical supply. Harmonics in your electrical systems could lead to:
- Increased energy consumption, thus increased operating costs
- Poor power quality & efficiency
- Reduced equipment lifespan & increased maintenance
- Interference with communication systems & other electronic equipment
- Reduced power system capacity, reducing reliability
- Tripped circuit breakers, blown fuses
- Increased neutral current, leading to overloaded systems & overheating, becoming a potential fire hazard

How to get rid of harmonics
Depending on the harmonic content of an electrical installation, we use either active or passive harmonic filters. We have found that these methods are the most effective and cost-effective.
Alpha Power is an expert in both power factor correction and harmonic filtration. With over 30 years’ experience, we have successfully helped our clients with solutions across a range of industries and applications.
Our harmonic filters eliminate or reduce to acceptable levels, distortions caused by harmonics.
Our harmonic filters
Alpha Power’s harmonic filtration filters are available in a passive or active range to best suit your application’s requirements. We can conduct a detailed analysis of your network to determine which filter will suit your application best.
There are two main types of harmonic filters: passive and active. Passive filters use a combination of capacitors and inductors to filter out harmonic frequencies, while active filters use power electronics to actively cancel out harmonics in real-time.
Here are a few key attributes of each filter:
|Active harmonic filters
|Passive harmonic filters
|More precise harmonic correction compared to passive filters since they tend to respond quickly to changes in harmonic levels
|No maintenance is required and they typically have a longer lifespan compared to active filters.
|Typically, more expensive than passive filters and require more maintenance.
|Lower cost and equipment specific.
|Handle higher levels of harmonic distortion than passive filters.
|Contains no electronic components, making them less vulnerable to general failures and failures caused by power surges.
|Need to be installed in well-ventilated rooms and generate a fair amount of noise (up to 65 dB).
|No power source is required to function, making them ideal for remote locations.
Industries we serve
Our harmonic filters benefit industries that use non-linear loads such as variable frequency drives, soft starters, LED lighting, and uninterruptible power supplies that create harmonic distortion in the electrical system.
The following is a list of industries we serve:
- Data Centres & IT
- Energy & Utilities
- Retail & Commercial Buildings
- Hospitality & Leisure
- Mining & Metals
- Chemical & Petrochemical
The two major contributors to harmonics include electronically controlled equipment and multiple electronic devices connected to your system. The nature of these electronics causes extremely quick pulses, creating a sine wave that becomes non-linear in shape. The end result affects the operation and longevity of your inter-connected systems and equipment.
By installing harmonic filtration units, these industries can improve power quality, prevent equipment damage, increase efficiency, and reduce operating costs!
