3 . About Harmonics Suppression Filters - Solution of harmonics problems of harmonics generating equipment Harmonic Filters are able to suppress unwanted harmonics caused by harmonic generating equipment in a factory low enough to comply with the guideline for harmonic suppression. Harmonic Filters solve harmonics problems of factory s power distribution system, also improves reliability and energy efficiency of electrical equipment. -2 Best solution for harmonics caused by general-purpose VFD These harmonic filters are suitable for harmonic suppression when industrial machines, such as fans, pumps, compressors, conveyors, and many others are operated at variable speed. Also, the filters are applicable regardless of such conditions as whether or not DC reactors are used in VFD s DC bus line, or whether the converter components are Thyristors or diode rectifiers. -3 Problems of harmonics Unlike noise (between approx. 50kHz and 30 MHz), harmonics ( Hz) have characteristics of being proportional to load current, having power enough to affect long distance, and being quantitatively measurable. If there are harmonics generating equipment including VFD, supply voltage distortion occurs and input current of harmonics generating equipment increases, which have multiple effects on factory facilities and control equipment. In addition, harmonics flow out from the user s power receiving point to the outside distribution system, and affect power factor correction capacitors, reactors and other equipment in the neighborhood. -4 Dealing with Government s guideline for harmonic suppression When specified users who receive power at medium or high voltage newly install / add / replace harmonics generating equipment, upper limits of harmonic currents coming out from the users are notified by the Agency for Natural Resources and Energy as Guideline for Harmonic Suppression. According to the criteria given through calculation designated by this guideline, the users are required to take countermeasures in order to maintain under the upper limits on harmonic currents flowing out from the power receiving point. The harmonic filters are products to suppress these harmonic currents. Example: Harmonics current waveform (50Hz) The figure below shows waveforms indicated by when the 5 th (250Hz), 7 th (350Hz) and th (550Hz) harmonic current simultaneously flow along with the fundamental frequency. Meanwhile, the waveform such as input current of VFD and others displayed by the oscilloscope, is compounded by frequencies of the fundamental, 5 times, 7 times, times and higher frequencies of the fundamental. 55th 77th Comparison of Harmonics in the Guideline Harmonics Content with VFDs Solutions for harmonics suppression THD-i (%)* Ki figure * Without reactors A reactor in AC Side 42.8 With a DC reactor 35.8 Reactors in AC Side and DC Side PHF Harmonic Filter (KS type) PHF Harmonic Filter (KB type) Compounded waveform shown with an oscilloscope th Fundamental freq *THD-i: Total Harmonic Distortion on currents *Ki figures: Conversion factors based on JEM-TR20 that indicates degrees of harmonic generation against a 6-pulse rectifier. 3

Most of harmonic currents generated by using 6-pulse rectifier system, is eliminated. Suppress harmonic currents inflow from power supply side, and prevent resonance with power supply equipment Protect the load and the capacitors in the filters from transient phenomena. Suppress outflowing harmonic currents from the load (VFD), and reduce the burden of shunt stage harmonics suppression. Prevent resonance between the shunt stage and the load (VFD). Absorb residual harmonics from input/output stages and minimize harmonics current distortion. 2-2 Characteristics of harmonics filters Harmonic filter PHF-KS type (3-reactor type) suppresses harmonics current distortion of VFD at 6% or less. As referential characteristics of harmonics, the right figure shows distortion factors in case of load fluctuation of 0% - 00% while %impedance of power supply transformer is between 0.%Z and 5%Z. Because of these characteristics, it is possible to clear the requirement of harmonics current outflow limit specified in the guideline for harmonics suppression when VFD are used. In case that the DC reactor is embedded in VFD, PHF-KB type (2-reactor type) is available, which shows nearly the same characteristics.

5 3 Outline of PHF Series Harmonics Filters 3- PHF Series line-up PHF Series are harmonics suppression filters for VFD, categorized into two types by circuit mode, namely KS type and KB type. KS type has a T-shape structure, having L and L2 reactors connected in series at power supply line of VFD, as well as having a L3 reactor and capacitors to configure a shunt circuit between L and L2. KB type is applied without L2 in case that the VFD includes a DC reactor (DCL) for total power factor improvement. Besides, each model has a different model No. by voltage and frequency as follow.

15 7 Components of PHF Series Harmonic Filters. PHF Series Harmonics Filters are composed of high precision 3-phase balance reactors and high performance capacitors. These are designed as natural convection cooling type and applicable up to 40 of ambient temperature (55 in-panel). They do not require fans, hence, realize high efficiency and high reliability. For the reactor, in order to achieve low loss and well-balanced inductance, split gap core structure technology is applied. Tolerance of inductance (mh) between three phases is +/-3% or less. Appearance of a Reactor The capacitor cell is a 3-phase capacitor (Δinternal connection structure) of metallic can containing metallized film. - Self-healing function in case of overvoltage - Circuit separation structure when inner pressure rises - The structure that contains damages by segment films - Display in case of failure: Pop-up of a terminal part Appearance of a Capacitor Appearance of a Capacitor Unit Nishitei Co., Ltd., Japan Head Quarter/Main Factory/Kyushu Sales Office: 2--, Kobai, Yahata-nishi-ku, Kitakyushu City, , Japan TEL: FAX: ksd@nishitei.co.jp Tokyo Sales Office: , Higashi-tokorozawa, Tokorozawa City, Saitama Pref., , Japan TEL: FAX: tso@nishitei.co.jp Osaka Sales office: #305, 7 th Chisan Bldg., 6-2-3, Nishi-nakajima, Yodogawa-ku, Osaka City, , Japan TEL: FAX: oso@nishitei.co.jp NS-B-000E.
