Line Reactors for Power Line Protection
Published on : Tuesday 01-06-2021
EMI Solutions, manufacturer of premium power quality products, launches the PURESINE series of AC Line Reactors.
Power quality is an important consideration in order to maintain the efficacy and reliability of electronic equipment, apart from uninterrupted power supply and handling EMI (electromagnetic interference). Natural and man-made phenomena such as harmonics, voltage fluctuations, lightning surge, flicker, commutation notches and interruptions on the power supply line are key causes that impact power quality.
Power quality products such as line and load reactors, harmonic filters and surge suppressors play a critical role in ensuring power quality for industrial and home needs.
EMI Solutions, a pioneer in the design and manufacturing of EMI and RFI power line filters, is launching a new product series for power line protection and power quality. The company brings this new range of AC Line Reactors under the renowned PURESINE series.
Line Reactors are electromagnetic devices (inductances) which consist of a steel core, electrical grade laminations and copper inductor coils. The coil forms a magnetic field as current flows through it, which limits the rate of rise of current. They are commonly used in Motor Drives, Automotives, Industrial Automation and other power quality applications.
The primary role of Line Reactors is to protect the VFD (variable frequency drives) from incoming line voltage distortion such as spikes and surges. Switching transients can peak over 1000 volts. The inductive characteristics of the Line Reactor restricts this sudden surge and eliminates nuisance tripping. By limiting the inrush current to the rectifier in the VFD, the Line Reactor Can minimise harmonic distortions. Depending on whether they are installed at the input side or output side of the VFD, they are known as line or load reactors.
The PURESINE PQR Series comprises Single Phase and Three Phase Line Reactors with 2% and 4% impedance for various power quality applications.
With increasing need in quality power, the PQR Line Reactors sets on to establish a benchmark in power line protection where Line Disturbances are common on power systems with power factor correction. Reactors in general are classified into line (input) and load (output) reactors. With the general construction of these reactors consisting of steel core electrical grade lamination and copper wound coils, they are well protected and thereby optimising performance. With emphasis on the Line (input) side, the PQR Series when connected between the AC line source and the input of a VFD, protects the drive from tripping nuisance and damages. An economical solution to reduced harmonic and power distortions with low ripple, our reactors limit the inrush current thereby efficiently improving the power factor. While our 2% impedance ratings are usually sufficient to absorb power line spikes and motor current surges. They prevent nuisance tripping of drives or circuit breakers in most applications. The 4% impedance reactors are best for reducing harmonic currents and frequencies. Use them when you must comply with IEEE 519. The additional impedance offered by the PQR series, minimises the current surge by balancing the drive input line current thereby improving the total power factor.
Reliability and efficiency being considered primary importance to business operations, be it machines, manufacturing equipment or office equipment; all power quality problems on either line site can be minimised by investing on EMIS range of reactors. Quality may have its cost, but poor quality definitely has a higher cost. As a result, designed in correspondence to EN 61558-2-20, EN 60076, UL 61800-5-1, EMIS range of Line Reactors ensures extended motor life and VFD Protection there by providing assistance to a variety of industry segments that rely on these machines.
