Grounding Measurement grounding terminal
This instrument is suitable for measurements on circuits that are not directly connected
to the grid power supply and circuits that are specially protected to be powered from the
(internal) grid. In the latter case, the transient stresses are different, and the instrument
should be used for this type of measurement to ensure that the peak transient voltage is
less than 3000 V.
Secondary electrical circuit connected to wall sockets through transformers or similar
equipment, such as electronic instruments and electronic equipment; electronic
equipment with protective measures, and any high-voltage and low-voltage circuits,
such as the copier in the office.
Primary electrical circuit of the electrical equipment connected to the indoor socket via
the power cord, such as mobile tools, home appliances, etc. Household appliances,
portable tools (e.g. electric drill), household sockets, sockets more than 10 meters away
from CAT III circuit or sockets more than 20 meters away from CAT IV circuit.
Primary circuit of large equipment directly connected to the distribution board and
circuit between the distribution board and the socket (three-phase distributor circuit
includes a single commercial lighting circuit). Fixed equipment, such as multi-phase
motor and multi-phase fuse box; lighting equipment and lines inside large buildings;
machine tools and power distribution boards at industrial sites (workshops).
Three-phase public power unit and outdoor power supply line equipment. Equipment
designed to "initial connection", such as power distribution system of power station,
power instrument, front-end overload protection, and any outdoor transmission line.
