Elite Power Systems India Private Limited

ELITE offers Hybrid Harmonic Filters. Harmonic Filter is a state of the art harmonic filter and the preferred choice of customers across variety of industries to solve their harmonic problems to avoid penalties and to improve performance of their electrical system. In cases where the preventive action presented above is insufficient, it is necessary to equip the installation with filtering systems.

Operating Principle:

• Passive and active filters are combined in a single system to constitute a hybrid filter. This new filtering solution offers the advantages of both types of filters and covers a wide range of power and performance levels.

• Industrial installations with a set of non-linear loads representing more than 500 KVA (variable-speed drives, UPSs, rectifiers, etc.)
• Installations requiring power-factor correction.
• Installations where voltage distortion must be reduced to avoid disturbing sensitive loads.
• Installations where current distortion must be reduced to avoid overloads.
• Installations where strict limits on harmonic emissions must be met.

ELITE offers Active Harmonic Filters. Active harmonic Filter is a state of the art harmonic filter and the preferred choice of customers across variety of industries to solve their harmonic problems to avoid penalties and to improve performance of their electrical system. In cases where the preventive action presented above is insufficient, it is necessary to equip the installation with filtering systems.

Operating Principle:

• These systems, comprising power electronics and installed in series or parallel with the non-linear load, compensate the harmonic current or voltage drawn by the load. Parallel-connected active harmonic conditioner (AHC) compensating the harmonic current (Ihar = I act). The AHC injects in opposite phase the harmonics drawn by the non-linear load, such that the line current Is remains sinusoidal.

Features:

• Commercial installations with a set of non-linear loads representing less
  than 500 KVA (variable-speed drives, UPSs, office equipment, etc.)
• Installations where current distortion must be reduced to avoid overloads

ELITE offers Passive Harmonic Filters. Harmonic Filter is a state of the art harmonic filter and the preferred choice of customers across variety of industries to solve their harmonic problems to avoid penalties and to improve performance of their electrical system. In cases where the preventive action presented above is insufficient, it is necessary to equip the installation with filtering systems. It offers both power-factor correction and high current-filtering capacity. Passive filters also reduce the harmonic voltages in installations where the supply voltage is disturbed. If the level of reactive power supplied is high, it is advised to turn off the passive filter at times when the percent load is low.

Operating Principle:

An LC circuit, tuned to each harmonic order to be filtered, is installed in parallel with the non-linear load. This bypass circuit absorbs the harmonics, thus avoiding their flow in the distribution network. Generally speaking, the passive filter is tuned to a harmonic order close to the order to be eliminated. Several parallel-connected branches of filters can be used if a significant reduction in the distortion of a number of harmonic orders is required.

• Industrial installations with a set of non-linear loads representing more
  than 250 kVA (variable-speed drives, UPSs, rectifiers, etc.)
• Installations requiring power-factor correction.
• Installations where voltage distortion must be reduced to avoid disturbing
  sensitive loads.
• Installations where current distortion must be reduced to avoid overloads.

Harmonic Filter is a state of the art harmonic filter and the preferred choice of customers across variety of industries to solve their harmonic problems to avoid penalties and to improve performance of their electrical system. In cases where the preventive action presented above is insufficient, it is necessary to equip the installation with filtering systems.
There are three types of filters:

• Passive
• Active
• Hybrid
