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
²
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 corresponding 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.
Creating Oscillographic Recordings for Tests
3.3.16
General
In order to be able to test the stability of the protection during switchon procedures also, switchon trials can
also be carried out at the end. Oscillographic records obtain the maximum information about the behaviour of
the protection.
Requirements
To be able to trip an oscillographic recording, parameter Osc Fault Rec. must be configured to Enabled in
the Functional Scope. Apart from the capability of storing fault recordings via pickup of the protection func-
tion, the 7SJ62/64 also has the capability of initiating a measured value recording via the operator program
DIGSI, the serial interface or binary input. In the latter case, the information
cated to a binary input. Triggering for the oscillographic recording then occurs, for instance, via the binary
input when the protection object is energized.
Those that are externally triggered (that is, without a protective element pickup) are processed by the device
as a normal oscillographic record. For each oscillographic record a fault record is created which is given its
individual number to ensure that assignment can be made properly. However, these recordings are not
displayed in the fault indication buffer, as they are not fault events.
Triggering Oscillographic Recording
To trigger test measurement recording with DIGSI, click on Test in the left part of the window. Double click
the entry Test Wave Form in the list of the window.
