positive indicating gound stations

English to Italian Tech/Engineering Electronics / Elect Eng Grounding

Si parla della messa a terra di tutte le parti di un sistema di travaso di liquidi infiammabili (in particolare per il riempimento di un'autocisterna).
Ecco il contesto:

• Install bond or ground instruments (e.g., ***positive indicating ground stations***) for all new truck loading racks to continuously monitor the connection. These instruments can be interlocked with control circuits to prevent loading pumps from being started when a good bond is not present; and/or alarmed so that operators are aware of lack of grounding.
