Grounding and power connection
Two independent ground connections are necessary- one for the test system and one for the EUT. These must be connected
back to the local permanent installation or to a fixed, permanent ground conductor. To avoid an electric-shock the power cord
protective grounding conductor must be connected to ground.
System GND
The system is connected to GND via the earth wire of the connected mains power cable for the generator and the EUT
supply. A separate GND wire from the reference GND plane to the building earth point may be useful to avoid interferences to
other areas.
EUT GND
Ensure that a reliable return path for the interference current is provided between the EUT and the generator. The GND wire
from the generator to the reference GND must be designed as a low inductance connection suitable for high frequencies. The
reference ground plane and the ground connections to the instruments, as described in the relevant test standards, serve this
purpose well.
Protection (optional)
A proposal is to separate protection of the EMC system with filters, insulation transformer or fault current protection, in
addition to other measures, may be useful for the EMC installation. The advantage is the separation of the EMC system from
all other installation.
A shielded room with adequate filters may be the best solution to avoid unwanted conducted and radiated interference to
other areas.
