Requirements
If the environmental conditions differ from those specified in section “Technical
data”, as to temperature and humidity, or if the atmosphere around the transformer
terminal contains chemically active gases or dust, the terminal should be visually
inspected in association with secondary testing. The visual inspection should focus
on:
• Signs of mechanical damage to the transformer terminal case and terminals,
• dust on the transformer terminal cover or case, and
• signs of corrosion on terminals, on the case or inside the transformer terminal.
For information about the maintenance of transformer terminals, refer to Section
“Service” on page 102.
Transformer terminals are measuring instruments and should be handled
with care and protected against moisture and mechanical stress,
especially during transport.
4.3.
Configuration
The RET 54_ transformer terminals are adapted to specific applications by using the
Relay Configuration Tool included in the CAP 505 tools. This tool is used for
configuring the basic terminal, protection and logic function blocks, control and
measurement functions, timers and other functional elements included in the logic
functions category (refer to Section “Transformer terminal configuration” on
page 31).
The MIMIC picture, alarm texts and LED indicators are configured with the Relay
Mimic Editor (refer to Section “MIMIC configuration” on page 32).
The configuration of LON network is described in section “LON network
configuration” on page 34. If the application includes no horizontal communication,
network variables are not needed and the section about LON network configuration
is thus not relevant.
The customer can configure the RET 54_ transformer terminal according to own
functional requirements and preferences or utilize the pre-engineered configuration
solutions.
For more detailed information about the configuration, refer to the Configuration
Guideline and the tool-specific manuals (refer to “Related documents” on page 9).
