6. Control
The IED offers control of one circuit breaker or
contactor with dedicated push buttons for
opening and closing. Control is achieved via the
IED’s LHMI or a remote system (for example, the
Protection and Control IED Manager COM600).
By default, the IED is equipped with a single input
interlocking scheme. For the creation of additional
interlocking schemes, secured object control
(SOC), blocking-based protection schemes or
external tripping, binary GOOSE messaging can
be used.
These additional protection and control schemes
required by specific applications are configured
using the LHMI, the WHMI and the optional
application functionality of PCM600. The LHMI
and the WHMI can be utilized for signal
configuration, while the PCM600 is required for
the configuration of the GOOSE messaging.
7. Measurement
The IED continuously measures the high-
impedance and neutral currents.
The measured values can be accessed locally via
the user interface on the IED front panel or
remotely via the communication interface of the
IED. The values can also be accessed locally or
remotely using the WHMI.
