True sine wave inverters serve two purposes: they convert Direct Current (DC) into sinusoidal Alternating Current (AC), and they help eliminate harmonic distortion that causes certain types of equipment to perform less efficiently and exhibit signs of high level harmonics. When it comes to converting DC to AC, the need for inverters is obvious. If DC power sources such as solar panels or wind turbines supply power to a facility, not converting the current to AC will cause fluorescent lighting ballasts, microprocessor-based computer equipment, and other sensitive electronics to operate inefficiently, if they operate at all.
 
Harmonic distortion is the manifestation of an input signal and output signal that have different frequencies. When the input signal passes through a device, additional harmonics may be added to the original frequency, resulting in a distortion of the frequency. The difference between input and output frequencies is expressed as a percentage of Total Harmonic Distortion (THD). Low percentages are typically unnoticeable to the senses, but high percentages can cause noticeable effects in sensitive electronics, such as computers and fluorescent lighting ballasts.
 
When it comes to eliminating harmonic distortion, knowing when to implement sine wave inverters is a bit trickier. In some cases, facilities have harmonic distortion in the line that doesn’t affect its equipment of electrical systems. When distortion does produce an effect, it can manifest in various ways. Overheating induction motors, failing power factor correction capacitors, overheating neutral conductors, and overheating transformers are just some of the problems that high level harmonics can cause in a facility. In a worst case scenario, the harmonics can be transmitted through utility equipment to neighboring facilities.
 
If your facility experiences problems that you suspect are caused by high level harmonics, you should have a provider of industrial power services examine the building’s electrical system and affected equipment. If it turns out that harmonic distortion is the culprit and implementing sine wave inverters would remedy the problem.
