3.3.15 Trip/Close Tests for the Configured Operating Devices
Control by Local
Command
If the configured operating devices were not switched sufficiently in the hardware test
already described, all configured switching devices must be switched on and off from
the device via the integrated control element. The feedback information of the circuit
breaker position injected via binary inputs is read out at the device and compared with
the actual breaker position. For devices with graphic display this is easy to do with the
control display.
The switching procedure is described in the SIPROTEC 4 System Description. The
switching authority must be set in correspondence with the source of commands used.
With the switch mode it is possible to select between interlocked and non-interlocked
switching. Note that non-interlocked switching constitutes a safety risk.
Control by Protec-
tive Functions
For OPEN-commands sent to the circuit breaker please take into consideration that if
the internal or external automatic reclosure function is used a TRIP-CLOSE test cycle
is initiated.
DANGER!
A test cycle successfully started by the automatic reclosure function can lead
to the closing of the circuit breaker !
Non-observance of the following statement will result in death, severe personal injury
or substantial property damage.
Be fully aware that OPEN-commands sent to the circuit breaker can result in a trip-
close-trip event of the circuit breaker by an external reclosing device.
Control from a
Remote Control
Center
If the device is connected to a remote substation via a system interface, the corre-
sponding switching tests may also be checked from the substation. Please also take
into consideration that the switching authority is set in correspondence with the source
of commands used.
