9.2.5

Differential protection

9.2.5.1

Overview

This group of settings covers differential protection of transformers. The system
needs rated data to function properly. If the protection object is for example, a
transformer, the rated current and voltage per winding as well as other relevant data
will be needed. The submenus under differential protection contain many other
settable parameters such as connection type (line side or busbar side), tap positions,
CT ratings etc. The data required depends on the protected object.

9.2.5.2

Transformer differential protection, two winding (PDIF, 87T)

Settings/GeneralSettings/TransformerDifferential/
TransformerDiff2Wind(PDIF)/T2D/TransformerDiff2Wind(PDIF)/T2D

Parameters for up to two instances of T2D can be set here. These include the rated
voltages and currents for windings, the connection types, the current transformer
ratings and various other parameters.

9.2.5.3

Transformer differential protection, three winding (PDIF, 87T)

Settings/General Settings/Transformer Differential/TransformerDiff3Wind/
T3D

Parameters for T3D can be set here. These include rated voltages and currents,
connection types (Y, D), current transformer ratings and various other parameters.

9.2.6

Control

9.2.6.1

Overview

Under Control in General settings, parameters for Apparatus control can be adjusted.
These are the parameters for among others Bay control, Switch controller,
Reservation input, Circuit breakers and Circuit switches. The parameters include
delay times, dependencies, pulse times and characteristics.
