Around 15 years ago, Mooser was the first EMC laboratory to consider how to test high-performance electric powertrains that have a high voltage. One result of these considerations was introduced in 2008: the first <a href=\"https:\/\/mooser-consulting.de\/en\/services\/echamber\/\">eCHAMBER<\/a><\/span><sup><strong style=\"background-color: var( --e-global-color-1aab2c3 ); font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, 'Noto Sans', sans-serif; font-size: 1rem;\">\u00ae<\/strong><\/sup><span style=\"background-color: var( --e-global-color-1aab2c3 ); font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, 'Noto Sans', sans-serif; font-size: 1rem;\">, a new test standtesting chamber concept that is specifically designed for high-voltage electric drivesdrive systems and electrically driven ancillarypowered auxiliary units, and which can reliably and thoroughly detects these faults.detect this interference.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-abf6444 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"abf6444\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-bc09d10\" data-id=\"bc09d10\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-7e3672d elementor-widget elementor-widget-image\" data-id=\"7e3672d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/mooser-consulting.de\/en\/services\/echamber\/\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/mooser-consulting.de\/wp-content\/uploads\/Mooser-eChamber-film-1280x720.jpg\" class=\"attachment-large size-large wp-image-4053\" alt=\"Mooser eChamber Movie\" srcset=\"https:\/\/mooser-consulting.de\/wp-content\/uploads\/Mooser-eChamber-film-1280x720.jpg 1280w, https:\/\/mooser-consulting.de\/wp-content\/uploads\/Mooser-eChamber-film-768x432.jpg 768w, https:\/\/mooser-consulting.de\/wp-content\/uploads\/Mooser-eChamber-film-1536x864.jpg 1536w, https:\/\/mooser-consulting.de\/wp-content\/uploads\/Mooser-eChamber-film.jpg 1920w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6bb56d2 elementor-widget elementor-widget-heading\" data-id=\"6bb56d2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\"><a href=\"https:\/\/www.mooser-consulting.de\/leistungen\/echamber-emv-messung\/\">The eCHAMBER\u00ae <\/a><\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f5039a4 elementor-widget elementor-widget-text-editor\" data-id=\"f5039a4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The eCHAMBER<sup>\u00ae<\/sup> sets standards with its drive concept, measurement methods and measuring precision.

measuring procedures for high-voltage systems ourselves. Aspects that have become very important in the meantime include measurements of high-frequency interference on motor shafts and the coupling of high-frequency inverter interference through the motor and through the mechanical transmission to the axles. Mooser is even able to simulate this interference from the inverter through the motor and the transmission without actually using a physical inverter, thus saving a lot of development effort and time and significantly improving the quality of the EMC measures at a very early stage in the development process. What is more, the Mooser measuring chambers are used to examine coupling from high-voltage to low-voltage electrical architectures, which is transmitted either through physical contact or in the form of a radiation field.<\/p><p>During the test planning phase, our engineers also benefit from their decades of participation in national and international standards committees. We played a key role in initiating the CISPR 25-4 and ISO\/TS 7637-4 standards for high-voltage systems and had a major influence on their contents. With the development of the <a href=\"https:\/\/mooser-consulting.de\/en\/services\/echamber\/\">eCHAMBER<sup>\u00ae<\/sup><\/a>, Mooser also initiated standardisation in 2008, as well as standardisation for chamber validation using the Long Wire method.

The majority of our employees have already completed this high-voltage safety training course provided by T\u00dcV Saarland, and the number is continuously increasing<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-1613b28 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1613b28\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-e0e07ef\" data-id=\"e0e07ef\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-20ff9da elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"20ff9da\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-b3cd81d elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"b3cd81d\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-83e51a9\" data-id=\"83e51a9\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3b73b21 elementor-widget elementor-widget-heading\" data-id=\"3b73b21\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Frequently asked Questions<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-dc6734c elementor-widget elementor-widget-toggle\" data-id=\"dc6734c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"toggle.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-toggle\">\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2311\" class=\"elementor-tab-title\" data-tab=\"1\" role=\"button\" aria-controls=\"elementor-tab-content-2311\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"icon icon-down-open-big\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened icon icon-up-open-big\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">What is \u201chigh voltage\u201d? <\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-2311\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"1\" role=\"region\" aria-labelledby=\"elementor-tab-title-2311\"><p>When systems and components in a vehicle are operated at voltages that exceed 30 volts AC or 60 volts DC, engineers refer to these as high-voltage (HV) systems.
