1.1 Application
The PCS-9611 relay is a protection, control and monitoring unit for various primary equipments
(such as overhead line, underground cable and transformer etc.) on solidly grounded, impedance
grounded, Peterson coil grounded and ungrounded system. This relay is suit able for wall surface
mounted indoors or outdoors or flush mounted into a control panel.
This relay can sample the analog values from the traditional instrument transformers, or receive
the sampled values from the electronic current and voltage transformers (via a me rging unit). The
binary inputs and outputs of this relay can be configured according to the demands of a practical
engineering through the PCS-Explorer configuration tool auxiliary software, which can meet some
special requirements of protection and control functions.
This relay can fully support the IEC61850 communication protocol and GOOSE function, and can
completely meet the demands of a modern digitalized substation.
The function diagram of this relay is shown in Figure 1.1-1 .
