– Who knows the REF stability procedure? Both the voltage injecting method And the current injecting method?
– When you create in the zone or out zone fault for REF stability there will always be a flow of current.
– Short Primary Bushing Phase R S T with secondary terminal shorted after CT. Then Inject One Phase Voltage, Then Current will flow through the Primary bushing and NHV. Inject current from low voltage side, in R phase and check for current (secondary current and display current in relay) at high voltage side.
Pl inject current outside the REF CT covering zones – relay should be stable (should not trip)

Reverse the R phase secondary terminals at TB(HV side) and take measurements ( display and secondary)
– What about lv side y,b phases? should be short or kept open?
– Open.
– Repeat for the Y and B phases. Then for R, Y B combined.
– Note that NGR must be shorted Or it would be burned.
– What if it’s a Delta star transformer?
– HV and LV CTs must-read values to short and reverse secondaries at TB.
– How to test REF on the Delta side if it’s available with an earthing transformer?
– I think this is the connection but I don’t know why we short ckt on the delta side two phases?
– Because a single phase-to-earth fault on the star side will get reflected as a phase-to-phase fault on the delta side?
– Is this shorting mandatory for star Transformers also?
– what if short all the primary phases?
– It’s only if we inject three phases, Current will also loop. we stability 3 phase then REF

– Creating the fault within zones – you can do this by closing Earth switches (outside the CT zones). Creating the virtual Earth fault through closing the earth switches (outside the REF CT zones).

– Which parameter (Measured or Derived) does the relay sense to trip the relay if the IN exceeds the setting? IN Measured or IN Derived?
– Check the Analog card whether a separate coil is provided for neutral.
Protection engineer user x: Which relay?
– It depends upon which factor you are using in settings.
– What is the issue? When I’m going to install PCM 600 v2.10 then this error will come.
– Which SQL Server is needed for PCM 600 v2.10?
– That’s telling 2014 express.

Protection engineer user x: Guys, If anyone has IEC 60870-5 – 101 & IEC 60870-5 – 104, then please send…
Protection user x: Is there any one user of the DEIF Controller?
Protection engineer user x: Anyone has an idea of IoS A & IREF N in ABB REF relays?
Protection engineer user x: IOS A & IREF N.
Protection user x:

– Why do we put an OLTC of the generator in local mode?
– Are you talking about the OLTC of Trs at Generation Station?
– Local it’s mean cannot access remotely, depending on operation requirements.


-We lost the password of the MicomP143 relay. Is there any option to reset the password?
– You need to contact customer care with security code device details

– What could be the possible cause of the increase in the current of one phase of a generator? My generator trips of overcurrent in Phase B. I have done all the checks on the generator and it seems okay.

– Is it possible to inject both 50Hz and 100Hz of two current sources in the CMC356 Kit?
– Yes, parallel sources 1 and 2 and use source 1 for 50Hz and source 2 for 100Hz.

– The above method should work for checking harmonic restraint blocking and tripping percentage. In my quick CMC, if I change 100hz then remaining all sources also will get changed into 100hz for harmonics.

– Right-click and select unsync.



– Can anyone explain the function of the three CTs on the neutral side?
– Possibly for generator differential protection. These CTs are connected on the main winding of Gen. However, on the neutral side of Gen and thus, referred to as neutral CT.
– I was thinking if done in residual connection then it will be used for stator earth fault protection on the neutral side. But the CTs are not residually connected.

  • Installing DIGSI 4
  • Managing Projects
  • Working with the Devices
  • Optimizing Parameterization

Sample page of the file:

The first step is to create a new project. The DIGSI Manager has been started, a project dialog box has not yet been opened.

Click File- New of the menu bar, enter a new project name and confirm with OK.

The project dialog box is displayed.

Names and symbols of all project containers are displayed in a hierarchical tree structure. To put it less complicated, we could say that containers are displayed. This pane is called a tree view. An opened folder is the first symbol to be displayed in this pane. The opened folder is designated as project 1 and represents the top level, the project itself.

The right pane of the window shows a folder-type object. If the DIGSI 4 Remote program is installed, a phone book type object and modem type object each are displayed in addition. Otherwise, this pane of the window continues to remain empty. This page serves to display further names of symbols of objects, which are contained in one of the selected containers of the tree view. To put it less complicated, we could say that this pane shows objects. Since the right pane of the window is represented as a list, this structure is called a list view.

Up to four objects are first automatically created within a new project of the tree view.
Project (cannot be inserted manually)
Folder (to structure a project)
Phone Book (station addresses for a modem connection)
Modem (for the communication  SIPROTEC between your computer and the SIPROTEC 4 device
modem connection for the storage of modem profiles).
Phone Book and modem will be created automatically if the DIGSI 4 Remote component has been loaded.

The SIPROTEC 4 device object type represents a real SIPROTEC 4 device with all its setting values and process data.

The V3/V2 device object type serves to create shortcuts linked to the V3/V2 devices within the project structure. These device data are processed with DIGSI-V3.x.

The SIPOROTEC 4 version object type is created to document different parameter settings groups of a SIPROTEC 4 device. The device address (VD number) of the corresponding versions is identical to that of the original device.

The left window pane contains the names and symbols of all project containers in a hierarchical tree structure.
The right window pane displays the objects of the selected folders. The structure is designated as a list view.

Your first step to creating a system-specific project structure is to insert folder-type blank containers in the corresponding levels.

Click a folder object to insert a subordinate folder via the menu command ® Paste. A maximum of 9 levels is the permissible hierarchy depth.

Several objects can be juxtaposed in parallel.

The names of the folders can be renamed to easily adjust to the requirements of your operation.

As a first step, you create a new project. The DIGSI 4 Manager is started, no project window is open.

  • Click File ® New in the menu bar.
  • In the New dialog box, enter Project 1 as a name for the new project.
    Don‘t modify any other settings.
  • Click OK.
    The project window is now displayed in the working range. Put it to full size.
  • An object of the type Hierarchical level is inserted automatically upon creating a new project.
  • Click this object and then click the selected name. Enter Region Nord as a new name.
  • Right-click an existing hierarchical level and insert the lower-level hierarchical level via the context menu Insert new object ® Hierarchical level. Enter the new name.
  • Click a hierarchical level, e.g. Feeder 1, and open the device catalog via the context menu.
  • Select the device and draw it on the hierarchical level.

The Device Catalog shows all SIPROTEC 4 devices available (installed) in the DIGSI 4 Manager.
The device catalog is an independent item. When you open the catalog, a button is created in the taskbar by Windows. The device catalog can remain open while working with the DIGSI 4 Manager to install all required SIPROTEC 4 devices.

Select a folder type object and click View ® Device Catalog to open the Device Catalog window.

The device catalog has a structure. Clicking a plus sign or double-clicking a folder icon will open the subordinate level.

For example, if you double-click 7SJ (time overcurrent protection), all installed SIPROTEC 4 devices with the device type names and the variant numbers will be displayed.

Short technical information is displayed on the lower catalog border for each device selected.

Note: Devices cannot be placed directly underneath the project folder!

The MLFB tab serves to determine the order number of the selected SIPROTEC 4 device in DIGSI 4. The order number is the code for the type and variant of the SIPROTEC 4 device. The order number is called the MLFB number.
Order number determination in DIGSI 4 affects all further parameterization options. Identical MLFB numbers are necessary for the communication between the DIGSI 4 device operation and the connected SIPROTEC 4 device. This is checked when setting up the connection.

The MLFB tab contains several drop-down list boxes. The drop-down list boxes related to the selected SIPROTEC 4 device are activated, only. These drop-down list boxes serve to select the order numbers to define the SIPROTEC 4 design and type in DIGSI 4.

As a first step, create a new project. The DIGSI 4 Manager is started, no project window is open.

Click File ® New in the menu bar.

  • In the New dialog box, enter Project 1 as a new project name.
    Don‘t change any other settings.
  • Click OK.
    The project window is now displayed in the working range. Put it to full size.

When creating a new project, an object of the type Hierarchical level is inserted automatically.

  • Click this object and then click the selected name. Enter Region North as a new name.
  • Right-click on an existing hierarchical level and insert a lower hierarchical level vie the context menu Insert new object ® Hierarchical level. Enter the new name.
  • Click a hierarchical level, e.g. Feeder 1, and open the device catalog via the context menu.
  • Select the device and draw it on the hierarchical level.
  • As a first step, create a new project. The DIGSI 4 Manager is started, no project window is open. Click File ® New in the menu bar.
    • In the New dialog box, enter Project 1 as a new project name.
      Don‘t change any other settings.
    • Click OK.
      The project window is now displayed in the working range. Put it to full size.

    When creating a new project, an object of the type Hierarchical level is inserted automatically.

    • Click this object and then click the selected name. Enter Region North as a new name.
    • Right-click on an existing hierarchical level and insert a lower hierarchical level vie the context menu Insert new object ® Hierarchical level. Enter the new name.
    • Click a hierarchical level, e.g. Feeder 1, and open the device catalog via the context menu.
    • Select the device and draw it on the hierarchical level.

Properties like object name, comment, or date of creation, have been assigned to all objects (General tab).
Some properties only refer to certain objects, for ex. the MLFB number for the SIPROTEC 4 devices or the device communication settings.
The values of the majority of the properties can be changed.

Select the object and click the View ® Details menu item to display the object properties. You can also open the Object Properties dialog box via the context menu or via the menu item Edit ® Object Properties

If the property values are grayed, they cannot be changed. Depending on the entries you made in other text boxes, such text boxes may be activated. Property values in white/empty text boxes can be edited.
