AC Elements Current Transformer

9.1 Current Transformer The properties associated with current transformers (CT) of the electrical distribution system can be entered in this editor. The Current Transformer Editor contains three pages of properties. • Info Page • Remarks Page • Comment Page

9.1.1 Info Page

Info

ID Enter a unique ID with up to 25 alphanumeric characters. PowerStation automatically assigns a unique ID to each current transformer. The assigned IDs consist of the default current transformer ID plus an integer, starting with the number one and increasing as the number of current transformers increase. The default current transformer ID (CT) can be changed from the Defaults Menu in the menu bar or from the Project View.

Operation Technology, Inc. 9-2 ETAP PowerStation 4.0

AC Elements Current Transformer

From & To Bus IDs for the connecting buses of a current transformer are designated as From and To buses. If a terminal of current transformer (From or To) is not connected to any bus, a blank entry will be shown for bus ID. If a terminal of a current transformer is connected to a branch (directly or indirectly), the ID of the branch will be displayed for the terminal connection. To connect or reconnect a current transformer to a bus, select a bus from the list box. The one-line diagram will be updated to show the new connection after you click on OK. Note that you can only connect to buses that reside in the same view where the current transformer resides, i.e., you cannot connect to a bus that resides in the Dumpster or in another composite network. If a current transformer is connected to a bus through a number of other protective devices, reconnection of the current transformer to a new bus from this editor will reconnect the last existing protective device to the new bus, as shown below where CT2 is reconnected from Bus10 to Bus4.

Next to the From and To bus IDs, PowerStation displays the nominal kV of the buses for your convenience.

In/Out of Service Operating condition of a current transformer can be selected by choosing either the In Service or Out of Service options. The properties of an Out of Service branch can be edited like an In Service branch; however, an Out of Service branch will not be included in any system studies. When Continuity Check is activated, an Out of Service branch automatically becomes dimmed in the one-line diagram. Note that the In / Out of Service option is an engineering property which is independent of the configuration status. Therefore, you can set a branch to be In Service for the Base Data and Out of Service in Revision Data.

To connect or reconnect a potential transformer to a bus, select a bus from the list box. The one-line diagram will be updated to show the new connection after you click on OK. Note that you can only connect to buses that reside in the same view where the branch resides, i.e., you cannot connect to a bus that resides in the Dumpster or in another composite network.

The secondary terminal of a PT has only one pin, which can be connected to voltmeters, multimeters, frequency relays, and voltage relays.

In/Out of Service The operating condition of a potential transformer can be selected by choosing either the In Service or Out of Service options. The properties of an Out of Service potential transformer can be edited like an In Service potential transformer; however, an Out of Service potential transformer will not be included in any system studies.
