HIGH RESISTANCE GROUNDING
IMPORTANT
Each DSP module is carefully inspected before packed in a specially designed carton. The unit should be examined
immediately upon receipt. If damage or indication of rough handling is apparent, a claim should be filed without
delay with the transport company. I-Gard should be notified promptly if replacements for damaged goods are
necessary. If units received are not to be installed immediately they should be stored in their original containers in an
area free of dust and moisture.
DSP Second Fault Protection – unnecessary outages of electrical power in continuous process industries or
in critical systems applications such as hospitals, air traffic control towers etc cannot be tolerated and this has
increased the usage of high resistance grounding systems.
The new DSP Ohmni System is designed to provide an alarm, but not trip when one ground fault occurs in the
system thus retaining system continuity. If a second fault develops on the system, before an existing fault has
been cleared, then the potential for serious damage results.
