Intell DIGIX works to deliver Innovative Engineering solutions with specific focus on energy efficiency and power quality enhancement. Like – Active Harmonic Filter, 3-Level Active Harmonic Filter, Multi-Level Active Harmonic Filter Etc.
Today, in this highly competitive world, operating costs have become a major concern for all industries. Power is a huge component of the operating cost for any industry. Poor quality and inefficient usage of power can increase leakages and lead to significantly inflated energy bills. Moreover, poor power quality, high harmonic distortions and high neutral current conditions lead to increased failure resulting in unintended and expensive downtimes.With our wide range of intelligent current conditioning solutions, we ensure that the industries draw (and pay for) only useful power from the grid and everything else is supplied by our Active Filters in real time. Our team of experts partners with industries to identify leakages
and critical sections; this allows us to deliver relevant solutions to reduce operating costs, pre-empt and eliminate unknown failures or nuisance trips and make the overall electrical infrastructure more efficient and reliable.

Harmonic Limits According to IEEE 519

The IEEE 519 standard specifies harmonic current limits to:

  • Limit harmonic current injection from customer loads, preventing voltage distortion on the utility’s power supply.
  • Maintain overall voltage quality by controlling harmonic voltage distortion on the mains power system.

    These limits are specifically applied at the Point of Common Coupling (PCC) — the interface between the customer’s electrical system and the utility supply.
