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 Rogowski or Combi sensors. 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 Combi sensors. The residual
voltage is calculated internally.
The signal marked with IA, IB and IC represents the three phase currents. The signal IG
represents the measured ground current.
