1. Description
RET630 is a comprehensive transformer
management IED for protection, control,
measuring and supervision of power
transformers, unit and step-up transformers
including power generator-transformer blocks
in utility and industry power distribution
networks. RET630 is a member of ABB’s
Relion
®
product family and a part of its 630
series characterized by functional scalability
and flexible configurability. RET630 also
features necessary control functions
constituting an ideal solution for transformer
bay control and voltage regulation.
The supported communication protocols
including IEC 61850 offer seamless
connectivity to various station automation
and SCADA systems.
2. Application
RET630 provides main protection for two-
winding power transformers and power
generator-transformer blocks. Two pre-
defined configurations to match your typical
transformer protection and control
specifications are available. The pre-defined
configurations can be used as such or easily
adapted or extended with freely selectable
add-on functions, by means of which the IED
can be fine-tuned to exactly satisfy the
specific requirements of your present
application. The optional voltage regulation
function is one example of such add-on
functions.
