3.4.3 Functional diagrams
The functional diagrams describe the default input, output, alarm LED and function-
to-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements.
The analog channels have fixed connections to the different function blocks inside the
protection relay’s standard configuration. However, the 12 analog channels available
for the disturbance recorder function are freely selectable as a part of the disturbance
recorder’s parameter settings.
The phase currents to the protection relay are fed from a current transformer. The
residual current to the protection relay is fed from either residually connected CTs, an
external core balance CT, neutral CT or calculated internally.
The phase voltages to the protection relay are fed from a voltage transformer. The
residual voltage to the protection relay is fed from either residually connected VTs, an
open delta connected VT or calculated internally.
The protection relay offers six different setting groups which can be set based on
individual needs. Each group can be activated or deactivated using the setting group
settings available in the protection relay or via binary input.
Depending on the communication protocol the required function block needs to be
instantiated in the configuration.
