Power Factor India Office buildings have undergone a significant modernization during the last years Large quantities of computer equipment (personal computer, printers, network servers) have been incorporated. All these equipment generate elevated levels of harmonics, which cause important problems in the electrical installation and the computer equipment itself. The triple harmonics (3rd, 9th etc.) are especially harmful as these sum in the neutral conductor and generate a high neutral current causing serious failures and damages in the installation. NAAC has developed a series of electromagnetic filters for elimination of harmonics named 'H.F. System'. These equipments are based on the cancellation and compensation of magnetic fluxes. The main advantage of the H.F. System is the absence of electronic components and capacitors. The H.F. System are therefore maintenance free, have an extremely long lifetime compared with other types of filters and are compatible with any electrical installation. Problem

• Malfunctioning and failure in computer equipment.
• Overheating of neutral conductors.
• Low efficiency and overheating of UPS, transformers and cables of the installation.
• Ripping of protections without apparent reason.
• Interferences in communication networks.
• Incremented power consumption.

Causes

• Low quality electrical energy.
• Elevated harmonic distortion in the voltage.
• Elevated neutral - earth voltage.
• High harmonic distortion in the current.
• Excessive levels of 3rd and 9th harmonics in the neutral conductor.
• Elevated true RMS current in the phases.
• Low power factor due to harmonics.
• Elevated losses in the electrical installation.

During the last years there has been a large modernization of the industrial production processes and a fast evolution in power electronics, especially in the field of power converters such as variable speed drives for DC motors, frequency converters, UPS. All these equipments have a common characteristic which is the generation of harmonics currents that reduce the quality of the electrical energy.

NAAC completes its range of filtering inductors with a range of electromagnetic harmonic eliminating devices named H.F. System. The functioning of these devices is based on the cancellation and compensation of magnetic fluxes. The main advantage of the H.F. System in the absence of electronic components and capacitors. The H.F. System are therefor maintenance free, have an extremely long lifetime compared with other types of filters and are compatible with any electrical installation.

Background

• The Activcomp is a state of the art, electronic switching system designed for Power factor Correction & Harmonic filtration.
• Connection and disconnection of the capacitors to and from the network occurs at zero current crossing. This smooth connection avoids the transient effects typically created by electro mechanically switched PFC systems.
  The electronic switches do not wear out or deteriorate during the switching process and the capacitors are not adversely affected by transients. These advantages contribute to a much longer life expectancy compared with electro mechanically switched PFC systems.
• The power factor is controlled very accurately by means of an advanced closed loop control & measuring unit, that takes into consideration all three phases and the effect of harmonics (1 through 63).

Very High quality Capacitor and Reactors are used in Activcomp system for P.F correction and Harmonic filtration. Capacitors are characterized by very high current bearing capacity of 4 X In and Low losses of 0.2 W / KVAr. As per tuning requirement of filter they are used in 525V or 690 V.

Neptune Filter Reactors are made out of high quality material and very stringent quality control.

The wave form of every cycle is continuously stored in on board memory for more than a year at high accuracy, allowing no gaps in data recording. In addition, a unique time synchronization algorithm assures that data from multiple locations is synchronized and displayed on the same time scale. The result is that every anomaly can be accurately analyzed and its source can be pinpointed definitively. Since all data is stored continuously and accurately over a long period of time, the M4000 is much more than an analysis device, but rather a full-fledged power quality data center.

NAAC offers comprehensive energy audit services for Industria l & Office Networks.

Energy Audit is a effective tool to check consumption patterns of various networks devices. It is normally carried out in two parts.

• Preliminary energy audit


• Detailed energy audit

Preliminary energy audit is carried out to check the areas of potential savings in the network. It also involves defining of scope of work which requires detail analysis & study.

Detailed Energy Audit is exhaustive depending on type of networks devices. It involves collection of data in detail from each and every area of operation, so as to calculate system efficiency. The collected data is then analyzed. The recommendations are based on these analysis to take corrective action.
