Cable shields, interference suppression capacitors and motor windings represent parasitic capacitances. In a fault-free system state, operational leakage currents flow through these parasitic capacitances to the protective conductor or via other conductive parts to the earth potential.<\/p>\n<p>Manufacturers and operators of devices and systems are fundamentally obliged to protect people against electric shock and to switch off sources of danger that could cause fires. Exactly these hazards can be caused by fault currents and must therefore be included in the safety considerations.<\/p>\n<p>For personal and fire protection in these systems, AC\/DC-sensitive residual current circuit breakers (RCCB) with rated residual currents of 30 mA are used. These rated residual currents are reached or even exceeded in many electrical systems during normal operation. In the past, the response to such problems was the impermissible expansion \/ bridging of the protective device or the lowering of the prescribed protective goals by using residual current devices with higher rated residual currents (e.g. 300 mA instead of 30 mA).<\/p>\n<p>Currents that are caused by insulation faults or by the human body (e.g. through contact) are fault currents. Only these currents should trip an AC\/DC-sensitive RCD and lead to the shutdown of a system.<\/p>\n<p>This important distinction between operational leakage currents on the one hand and fault currents due to human contact or insulation problems on the other hand cannot be made by today&#8217;s residual current protective devices. Therefore, unwanted shutdowns by the protective device very often occur without an actual fault. The consequences can be expensive downtimes and restart times as well as production scrap.<\/p>\n<hr \/>\n<h2>The solution<\/h2>\n<p><a href=\"https:\/\/epa.de\/filter\/de\/wp-content\/uploads\/sites\/3\/2015\/06\/leakcomp-mit.png\" data-rel=\"lightbox-image-1\" data-rl_title=\"\" data-rl_caption=\"\" title=\"\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-965\" src=\"https:\/\/epa.de\/filter\/de\/wp-content\/uploads\/sites\/3\/2015\/06\/leakcomp-mit-1024x786.png\" alt=\"leakcomp-mit\" width=\"640\" height=\"491\" \/><\/a><\/p>\n<p>With the <strong>LEAK<\/strong>COMP<sup>\u00ae<\/sup> <strong><i>HP<\/i><\/strong>, the operational leakage currents are determined by measuring technology and compensated for in a complex and patented process for residual current circuit breaker.
