IEEE 1560-2005 pdf download IEEE Standard for Methods of Measurement of Radio-Frequency Power-Line Interference Filter in the Range of 100 Hz to 10 GHz
1. Overview
1.1 Scope
The scope of this standard is to develop a standard method of measurement for evaluating theelectromagnetic and radio frequency suppression capability of power-line filters in the frequency range of100 Hz to 10 GHz. This will apply to electromagnetic interference/radio-frequency interference (EMI/RFl)filters in general, i.e, dc, single-phase or polyphase systems rated for 600 V and below 1000 A. The methodof measurement will describe general considerations, such as the method of standardizing source impedancefor nonlinear loads, temperature rise, attenuation measurement, components, and or derating requirementswhen supplying nonsinusoidal load currents and operating in matched- or mismatched-impedanceenvironments.
1.2 Purpose
The purpose of this standard is to provide measurements that evaluate the performance of power-lineinterference filters in practical installations involving varying load and source impedances. These factors arenot usually considered in design and performance verification testing of EMI/RFI filters. Bothmanufacturers and end users should benefit from this standard that defines the ranges and environment.expected effects, and test methods to yerify filter attributes.
1.3 Application of test methods and use of this document
Clause 10 describes filter performance measuring techniques. Although it might be desirable to characterizeeach production filter in accordance with all the measurement methods described, it is generally noteconomically feasible to do so. Usually, only first-design filters will be analyzed through multipleperformance tests. These tests establish a performance baseline for that filter design. Subsequent productionunits of the same design may be tested using matched-impedance techniques to ensure that there is nosignificant deviation from the original due to component or assembly changes.
Case design and assembly testing may be required on a need basis to ensure control of radiated emissionsfrom the filter at frequencies above 1 GHz. There are several methods for observing case integrity that donot employ RF testing to ensure proper case construction. These include the die penetration methodHowever. it is recommended that radiated field testing be perforred at the imstallation site with the filter inits final configuration on a shielded enclosure for best results at freuencies above 1 GHz.Refer to IEEE Std29gm l Where it is not possible to perform the test with the filter in its final configuration, then reasonablescreening or enclosures may be used.
Clause 10 is divided into cight test methods (see 10.1-10.8). alphabetically coded in Table B.l. It isdesirable to label all power-line filters in a similar manner in accordance with Annex B. The nameplate datamay be derived from the different tests outlined in Clause 10. Annex F illustrates generic filter curves andpoints of interest such as the 3 dB point, 20 dB point, and the ratio calculations of the shape factor, whichmay be requested to be printed with the filter curves in the original baseline data
1.3.1 Use of test methods
1.3.1.1 Quality assurance tests
Quality assuranceNo load (10 kHz to 1 GHz) (see 10.1)Quality assuranceLoaded (10 kHz to 20 MHz) (see 10.2)
The quality assurance (OA) test follows traditional matched-impedance testing methods currently in practiceby most manufacturers. The frequency ranges are selected based on reproducibility, QA control indicators.and reasonable performance frequencies where the filter might be operating under varying loads
