Air Core Reactors: Motor starting reactors, Filter reactors, Damping reactors, Earthing reactors, Short circuit current limiting reactors, Reactors for testing facilities<\/h2>\n

[\/vc_column_text][vc_column_text]Besides its iron core inductances, FDUEG has plenty of experience in manufacturing air core dry type reactors for industrial applications and special environment and load conditions, both as single phase or as three phase configuration. The main categories of such product are listed here below.[\/vc_column_text][vc_images_carousel images=”2658″ img_size=”full” onclick=”link_no” hide_pagination_control=”yes”][vc_row_inner css=”.vc_custom_1556550758627{margin-top: -185px !important;margin-bottom: 10px !important;border-radius: 3px !important;}”][vc_column_inner width=”1\/3″]

Motor starting reactors<\/a><\/h3>\n

[\/vc_column_text][vc_column_text]They limit the inrush current at the start on induction motors. Placed on the incoming line, they allow to diminish the current from 5\/8 times the rated to lower and more acceptable values (around 2.5\/3 times), before being bypassed for regular operations.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner css=”.vc_custom_1557479417715{margin-bottom: 10px !important;border-top-width: 1px !important;border-top-color: #eaeaea !important;border-top-style: solid !important;}”][vc_column_inner width=”1\/3″][vc_single_image image=”1633″ img_size=”full” alignment=”center” onclick=”custom_link” link=”https:\/\/www.fdueg.com\/en\/harmonic-filter-reactor\/”][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n

Filter reactors<\/a><\/h3>\n

[\/vc_column_text][vc_column_text]They filter AC current harmonic, removing them from the power supply. Through L-C coupling, the resulting tuned filter is specifically designed to absorb a frequency, multiple of the fundamental, produced by power electronic components such as rectifiers.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner css=”.vc_custom_1557479423524{margin-bottom: 10px !important;border-top-width: 1px !important;border-top-color: #eaeaea !important;border-top-style: solid !important;}”][vc_column_inner width=”1\/3″][vc_single_image image=”1638″ img_size=”full” alignment=”center” onclick=”img_link_large”][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n

Damping reactors<\/h3>\n

[\/vc_column_text][vc_column_text]Their action is twofold: they limit the inrush currents resulting from the switching of battery banks and capacitors, while also smoothing fault currents in case of short circuit. During regular operations, they reduce the dielectric stress on the insulation system and prevent unwanted damage on the capacitors\u2019 terminals.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner css=”.vc_custom_1557479423524{margin-bottom: 10px !important;border-top-width: 1px !important;border-top-color: #eaeaea !important;border-top-style: solid !important;}”][vc_column_inner width=”1\/3″][vc_single_image image=”3682″ img_size=”full” alignment=”center” onclick=”custom_link” link=”https:\/\/www.fdueg.com\/en\/earthing-transformer-for-power-system\/”][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n

Earthing reactors<\/a><\/h3>\n

[\/vc_column_text][vc_column_text]They connect to ground the neutral of a system, so that their impedance reduces the current in case of fault between phase and earth. If tuned as Petersen coils, these air core reactors remove fault currents through capacitive coupling, protecting personnel and equipment.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner css=”.vc_custom_1557479423524{margin-bottom: 10px !important;border-top-width: 1px !important;border-top-color: #eaeaea !important;border-top-style: solid !important;}”][vc_column_inner width=”1\/3″][vc_single_image image=”1643″ img_size=”full” alignment=”center” onclick=”custom_link” link=”https:\/\/www.fdueg.com\/en\/current-limiting-reactors\/”][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n

Short circuit current limiting reactors<\/a><\/h3>\n

[\/vc_column_text][vc_column_text]They limit fault currents in transmission lines to levels that are compatible with the protection devices installed; thus, their presence allows the choice of cheaper components or to upgrade the existent power system to higher capabilities without substituting the breakers.<\/p>\n

While sporting constant impedance both if heavily or lightly loaded, a short circuit current limiting reactor by FDUEG has a focus on mechanical resistance to sustain the design condition fault in magnitude and duration.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner css=”.vc_custom_1557479423524{margin-bottom: 10px !important;border-top-width: 1px !important;border-top-color: #eaeaea !important;border-top-style: solid !important;}”][vc_column_inner width=”1\/3″][vc_single_image image=”1648″ img_size=”full” alignment=”center” onclick=”custom_link” link=”https:\/\/www.fdueg.com\/en\/testing-lab-reactors\/”][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_column_text]<\/p>\n

Reactors for testing facilities<\/a><\/h3>\n

[\/vc_column_text][vc_column_text]Used to simulate the operational conditions on samples under test. Tailored upon the customer\u2019s requests, they find their application in testing mechanical switches, capacitors, loads in need for current limitation, power factor correction or construction of artificial loads. They can support large regulations, particular duty cycles, high voltage or current; if assembled in a bank, their combination allows to create multiple inductive values.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_empty_space height=”25″][\/vc_column][vc_column width=”1\/3″ css=”.vc_custom_1555579008876{border-right-width: 1px !important;border-left-width: 1px !important;border-left-color: #eaeaea !important;border-left-style: solid !important;border-right-color: #eaeaea !important;border-right-style: solid !important;}”][vc_column_text css=”.vc_custom_1559807204805{margin-top: 25px !important;margin-bottom: 1px !important;border-bottom-width: 1px !important;}” el_class=”pdfnascosto”]<\/p>\n
