ABSTRACT:
A detector circuit for detecting an unwanted ground coupled to either terminal of an ungrounded d.c. power supply. The circuit uses simple and economical components including four resistors, two diodes and a single voltage comparator. The resistors provide two voltage dividers whose midpoints are at different potentials. The two midpoints are coupled by the two diodes in series with the midpoint of the diodes grounded. A voltage comparator is coupled to the voltage divider midpoints. Any unwanted ground will shift the relative polarity of the voltage divider midpoints and alter the output signal of the voltage comparator.
