			<description><![CDATA[Please re-post if in wrong section.<br />
<br />
Hi could someone be so kind to answer me this question for ease of mind.<br />
<br />
If you have roughly around 25 volts to earth from a 50 volt DC busbar, and by changing one of the filters within the transformer that it derives from rectifies the leakage to earth, can someone just clarify the electrical principle behind what is happening in this instance, many thanks in advance.]]></description>
