Application Mode of operation
The test switch serves in the testing
of protection devices using
secondary injection test sets, for
example 7VP15 (Omicron CMC
56).
The following versions are in a
flush mounting case available:
• For feeder protection without an
open starpoint.
• For feeder protection without an
open starpoint and with additional
contacts.
• For feeder protection without an
open starpoint for two CT cores
or separate earth fault CT.
• For feeder protection with an
open starpoint.
• For feeder protection with an
open starpoint and independent
switchable trip and c.t. circuits.
• For a 3-winding transformer
differential protection.
• For feeder protection without an
open starpoint, with 4th CT and
4th VT input (three-stage test
switch)
The test device can be used with
auxiliary supplies ranging from
24 V to 250 V DC. This makes
selection between varying power
supply models unnecessary.
