PD-TaD 62
Connecting the system
822-187-3
39 / 114
Procedure
Important:
To keep the connection cable between the PD-TaD and the test object short, place the
PD-TaD as close as possible to the test object.
To avoid interference due to partial discharge at the connection point, make sure the PD-
TaD is placed a sufficient distance away from metal and live parts.
If the connection point is higher up, put the PD-TaD on a substructure. Further
information: Chapter
Securing the PD-TaD 62 to the cross beam
(on page 33)
Keep all connections as short as possible.
Lay out the connection cables in such a way that no loops are created.
The numbering in the table gives the sequence of steps for connecting the test object.
