21/776 Electrical Power Engineering Reference Applications Handbook discussed below. Normally four types of RCDs are in use 10 mA 30 mA 100 mA and 300 mA IEC 61008 9). Figure b) shows some views of RCDs.
system grounding is the ratio of the available groundfault current to the available threephase fault current. For effectivelygrounded systems this ratio is usually at least 60% . Most utility systems which supply service for commercial and industrial systems are solidly grounded. Typical
