Figure 249: Example of an autoreclosing program with a reclose scheme matrix
In the AR function, each shot can be programmed to locate anywhere in the reclose
scheme matrix. The shots are like building blocks used to design the reclose program. The
building blocks are called CBBs. All blocks are alike and have settings which give the
attempt number (columns in the matrix), the initiation or blocking signals (rows in the
matrix) and the reclose time of the shot.
The settings related to CBB configuration are:
• First...Seventh reclose time
• Init signals CBB1…CBB7
• Blk signals CBB1…CBB7
• Shot number CBB1…CBB7
The reclose time defines the open and dead times, that is, the time between the
OPEN_CB
and the
CLOSE_CB
commands. The Init signals CBBx setting defines the initiation
