5.3. Switch control
5.3.1. Introduction
The
ekor
.rpa-100 units are equipped with inputs and
outputs to operate the switch of the cubicle where are
installed, and monitoring functions that detect the status
of the primary circuit. The unit ensures that the switch
operation is performed within the time allowed by the
switchgear. The
ekor
.rpa-100 units also indicate the
earthing switch position. Moreover, the unit can monitor
the tripping circuit.
Apart from the functions of operating and monitoring
the status of the switch and other functions mentioned
above, the switch control unit includes the switch error
automation (50BF/State method). This automation consists
of timing using a configurable meter once the system has
activated the opening order (due to protection tripping,
remote opening operations, external tripping, etc.) or the
closing order (due to reclosing, remote closing orders, etc.).
If the meter expires before the system detects the change in
switch status, it will give a switch error indication, indicating
the origin of the opening or closing order. If the system sees
the change in switch status before the meter expires, it will
give an opening or closing correct indication, indicating the
origin of the opening or closing order.
