Abstract:
A system for determining DC leakage current flowing through an electrically insulating structure in a high voltage direct current power system is provided. The DC leakage current is a composite DC current. The insulating structure is operatively coupled to at least an overhead energized DC electrical line. The system further includes a direct current meter adapted to be electrically coupled to at least the insulating structure. The meter includes a waveform separator. The separator is configured to receive and separate the composite DC current into a corresponding direct current (DC) and an alternating current (AC) component. The separator further includes at least one comparator which is configured to produce at least one corresponding digital signal from the AC component; and a processor. The processor receives and analyzes the at least one corresponding digital signal and the DC component to determine a resultant leakage current flowing through the insulating structure.

Claim (Index 1):
A system for detecting leakage current in high voltage direct current power systems having an energized DC electrical line above an Earthen surface comprising:\n a substantially electrically insulating structure having a first end adapted to be located proximate to, and electrically connected to, the energized DC electrical line, and a second end adapted to be located towards the Earthen surface; a direct current meter adapted to be electrically coupled in series between the insulating member and the Earthen surface, wherein the direct current meter is configured to detect a plurality of momentary leakage current values flowing through the substantially electrically insulating structure when electrically coupled to the direct current meter, and wherein the direct current meter includes a waveform separator system for determining DC leakage current flowing through the insulating structure, wherein the DC leakage current is a composite DC current comprising one or more high magnitude momentary spikes, and having a DC component and an AC component, and wherein the wave form separator system includes: a waveform separator configured to receive the composite DC current flowing through the insulating structure and to separate the composite DC current into corresponding direct current (DC) and alternating current (AC) component wherein the AC component has a first rate of change, and wherein the DC component has a second rate of change, and wherein the first rate of change is greater than the second rate of change; at least one comparator configured to receive the AC component and produce at least one corresponding AC digital signal; and a processor configured to: (a) receive the at least one corresponding AC digital signal and the DC component, (b) analyze the at least one corresponding AC digital signal and the DC component, and (c) determine a resultant leakage current flowing through the insulating structure.
