B-1.5 Single Point Grounding
Figure B-7: Single point grounding. (1)
• What’s Single Point Grounding? Maybe you have had an
unpleasant experience while taking a hot shower in Winter.
Someone turns on a hot water faucet somewhere else. You
will be impressed with the cold water! The bottom diagram
above shows an example of how devices will influence each
other with swift load change. For example, normally we turn
on all the four hydrants for testing. When you close the
hydrant 3 and hydrant 4, the other two hydrants will get more
flow. In other words, the hydrant cannot keep a constant flow
rate.
