Block OFF
The function registers its operation into the last twelve (12) time-stamped registers. The register of the
function records the ON event process data for START, TRIP or BLOCKED. The table below
presents the structure of the function's register content.

5.3.16 Transformer status monitoring
The transformer status monitoring function is designed to be the one place where the user can set up
all necessary transformer data and select the used transformer protection functions. Settings related to
the protection functions can also be edited inside each function and any changes are updated into this
function as well. The function calculates many transformer-related properties which are used in
functions that protect and monitor the transformer. Standard transformers require only name plate data
and CT scalings to get the relay automatically scale all measurement signals to the transfomer. In
special transformers manually set values can be applied to cover the transformer properties that are
rarely met. Additionally, the function counts a transformer's cumulative overloading and high
overcurrent time.
The function can output the following signals:
• light/no load
• HV side inrush
• LV side inrush
• normal load
• overloading
• heavy overloading.
These signals can be used in indication or in logic programming, and they are the basis for the events
the function generates (if so chosen).
