What’s Single Point Grounding?
Maybe you had some displease experiences just like take hot water
shower in Winter. When someone turns on another hot water hydrant
near the Heater, you’ll be impressed with the cold water!
The bottom diagram of above figure just shows that those devices will
influence each other with swiftly load change. For example, normally
we turn on all the four hydrants for testinF. When you close the
hydrant 3 and hydrant 4, the other two hydrants will get a more flow. In
other words, the hydrant can not keep a constant flow rate.
