ABB rec670 Commissioning Manual

1. Check the function settings on the local HMI under Main menu/Settings/
Setting group N/Control/Autorecloser79,5(0–>1)/SMBRREC:x
If any timer settings are reduced to speed up or facilitate the testing, they shall be
set to normal after testing. A temporary label on the IED can be a reminder to
restore normal settings after which a verification test should be performed.
2. Decide if a synchronizing check function SESRSYN shall be included in the
test.
If SESRSYN as an internal function or external device is not operated by the
injection, input signal SYNC must be connected as a permanent high signal or
controlled by a switch.
3. Read and make notes of the reclosing operation counters on the local HMI under
Main menu/Test/Function status/Control/AutoRecloser79,5(0–>1)/
SMBRREC:x
Possibly reset the counters to Zero. Counters are reset in the reset menu.
4. Make arrangements for the simulation of the CB, for example as in figure
25.
5. Make arrangements for indication, recording and time measurements.
The signals for CBPOS, START, CLOSECB, READY and other relevant
signals should preferably be arranged for event recording with time tagging. If
that is not possible, other means of time measurement and recording should be
arranged.
10.9.2.2 Switching the autorecloser for 1/2/3-phase operation function to
On
and Off
1. Set the Operation setting to Off and check the state.
2. Set the Operation setting to On and check the state, including SETON and
READY.
The CB should be closed and ready.
3. If external control inputs OFF/ON are used, check that they work. Set
ExternalCtrl = On and use the control inputs to switch On and Off, and check the
state of the function.
10.9.2.3 Verifying the autorecloser function SMBRREC
Select the test cases to be run according to what is applicable to the particular
application. It can be, for example,
• three-phase single-shot reclosing
• two-shot reclosing
• single-phase and three-phase single-shot reclosing
Below, a case with single-phase and three-phase single-shot reclosing is described.
