ⅩI. Field Application
1. Multi-Point Grounding System
As for the multi-point grounding system (such as electricity
transmission tower grounding system, grounding cable
communications systems, certain buildings, etc.), They usually
pass the overhead ground wire (cable shielding layer) connected
to form a grounding system.See below. As the Meter is in the
above measurement, its equivalent electric circuit is shown in the
