10.1 Apparatus control
10.1.1 Functionality
The apparatus control functions are used for control and supervision of circuit
breakers, disconnectors and grounding switches within a bay. Permission to operate is
given after evaluation of conditions from other functions such as interlocking,
synchronism check, operator place selection and external or internal blockings.
In normal security, the command is processed and the resulting position is not
supervised. However with enhanced security, the command is processed and the
resulting position is supervised.
