It was created with the help and input from a broad range of involved stakeholders: network operators, equipment manufacturers, universities, accredited test houses and consultants.<\/p>\n<p>Beside the actual standardization situation it reflects the current emission situation found in supply networks and installations and describes electromagnetic interference (EMI) cases from twelve countries; investigation and analysis of the latter show a wide range of different types of electrical devices to be considered as a source or a victim of related EMI.<\/p>\n<p>This Technical Report highlights the occurrence of high levels of non-intentional emissions (NIE) in the considered frequency range, including values up to and exceeding the standardized limits for intentional signals from mains communicating systems (MCS), which also implies a high potential to cause EMI to other electrical equipment. On the other hand, several types of equipment show susceptibility to related emissions, being insufficiently immune.<\/p>\n<p>The Technical Report addresses the following issues:<\/p>\n<ul>\n<li>\n<p>a number of different types of electrical equipment are generating such emissions and\/or are susceptible, to such, thus representing EMI potential, as a source or a victim of such EMI;<\/p>\n<\/li>\n<li>\n<p>the interaction of electrical equipment in a certain supply area respectively installation, with its complex and volatile impedance character, as having an additional EMI potential; that besides NIE from general electrical equipment and signals from MCS and technically being quite different from emissions;<\/p>\n<\/li>\n<li>\n<p>the fact that besides the conducted interference also radiated interference from NIE or signals from MCS, through the magnetic H-field following to related currents on the mains, is to be considered, what is of some importance also for the interference-free operation of broadcast time-signal systems or electronic circuits controlled by such;<\/p>\n<\/li>\n<li>\n<p>the ageing of electronic components in electric equipment, which causes increased emissions and EMI to other electrical equipment as a result of not showing the same EMC characteristics as before being placed on the market, therefore no longer being able to conform with EMC requirements;<\/p>\n<\/li>\n<li>\n<p>the additional aspect of differential mode operation, which should be considered for related immunity and testing specifications.<\/p>\n<\/li>\n<\/ul>\n<p>These findings confirm that EMI in this frequency range is not limited to single types of equipment like inverters or MCS; instead a more general electromagnetic compatibility (EMC) problem concerning a larger spectrum of electrical equipment is identified.<\/p>\n<p>Although a case-by-case mitigation of related EMI cases might be seen as appropriate, the increasing application of technologies and systems with related EMI potential requires a more general solution, through standardization, taking a balanced viewpoint of EMC and economics into account. With regard to the actual standardization situation, a review of the actual EMC and Product standards based on the reported results seems to be advisable.<\/p>\n<p>After initiating the work in <span class=\"std\"> <span class=\"std-ref\">CLC\/SC&nbsp;205A<\/span> <\/span>, the now ongoing work in <span class=\"std\"> <span class=\"std-ref\">IEC&nbsp;SC&nbsp;77A<\/span> <\/span>, as well as the publication of a related Technical Report on testing electricity meters <span class=\"xref\">[2]<\/span> by CLC\/TC 13 and of the new Immunity testing standard <span class=\"std\"> <span class=\"std-ref\">EN&nbsp;61000\u20114\u201119<\/span> <span class=\"xref\">[99]<\/span> <\/span>, appear as right steps into the right direction but needing further, extended efforts.<\/p>\n<p>As stated on European as well as on international EMC standardization level, the availability of compatibility levels for the considered frequency range appears as a key-requirement for future considerations on setting related emission limits and immunity requirements in various standards. A fundamental basis for the coexistence of intentional signals from MCS and NIE needs to be found.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Study Report on Electromagnetic Interference between Electrical Equipment\/Systems in the Frequency Range Below 150 kHz<\/b><\/p>\n<table class=\"shortdes-table\" style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/bsi\/\"><b>BSI<\/b><\/a><\/td>\n<td>2015<\/td>\n<td>88<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":252573,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[624,2641],"product_tag":[],"class_list":{"0":"post-252572","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-33-100-01","7":"product_cat-bsi","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/252572","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/252573"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=252572"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=252572"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=252572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
