SICAM P850/P855 7KG85xx, Product Information
E50417-B1050-C482-A3, Edition 03.2013
10.5
Setting the Parameters
11 Connection Types
The following input wiring diagrams are examples. Up
to the maximum allowable current and voltage values
(see Chapter 19.1) SICAM P850/P855 can also be
connected without interconnected current and voltage
transformers.
Required voltage transformers can be operated in star
connection or delta connection.
All input and output terminals not needed for
measurements remain unwired.
NOTE
The parameterization is described in the device
manual, order number E50417-H1040-C482.
NOTE
The illustration of the consistent ground connection of
the instrument transformers is simplified in the following
connection examples. The secondary windings of the
current transformers installed in a high-voltage power
system must be grounded on one side.
DANGER
Hazard due to high voltages in the event of a break-
down of the winding insulation
Non-observance will lead to death or serious injury.
Ground the secondary windings of the current trans-
formers on one side. They are installed in a high-volt-
age power system.
