Harmonics Solutions
Price On RequestTCIPL provides end-to-end consulting and solutions to contain
Harmonics in electrical systems which arise due to the presence and
installation of non-linear electronic devices in the system. The team
has a clear understanding of the requirements of the CEA and identifies
and recommends solutions to bring in Harmonics within levels as
stipulated by the Electricity Boards. A dedicated team with a deep
understanding of the subject works closely with customers to carry out
studies related to harmonics at their sites and provide customized
cost-effective solutions through the use of Passive or Active Harmonic
Filters.
What causes Harmonics?
Loads can be broadly categorized into linear and non-linear
loads. When the load draws a sinusoidal current at the same frequency as
the voltage it is classified as linear load. Examples of linear loads
are resistive heaters, incandescent lamps, and constant speed induction
and synchronous motors.
Some loads cause the current to vary disproportionately with the
voltage during each cyclic period. These are classified as nonlinear
loads, and the current taken by them has a nonsinusoidal waveform.
Current harmonics are caused by non-linear loads. Examples of non-linear
loads include common office equipment such as computers and printers,
Fluorescent lighting, SMPS, battery chargers and also variable-speed
drives.
What are the industries effected by Harmonics?
In the past, non-linear loads were primarily found in heavy
industrial applications such as arc furnaces, large variable frequency
drives (VFD), heavy rectifiers for electrolytic refining, etc.
Harmonic problems are now common in not only industrial
applications but in commercial buildings as well. This is due primarily
to new power conversion technologies, such as the Switch-mode Power
Supply (SMPS), which can be found in virtually every power electronic
device (computers, servers, monitors, printers, photocopiers, telecom
systems, broadcasting equipment, banking machines, etc.).
