– 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).

– You can download it from www.Schneider-electric.com

– 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 sendโ€ฆ
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 requirement.


-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 current of one phase of a generator? My generator trips of overcurrent in Phase B. I have done all 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

The parameter set cannot be transferred to the device.

The reason for this is that the parameter for the EN100 module has not yet been updated after changing the IEC61850 system interface. To do so, open the “update” property page of the IEC61850 station and update all parameter sets. A transfer to the device now works again.

Details Course

Part 1: Substation Automation- Overview

substation protection and control systems development, from conventional to digital substations with some pictures of a real substation. Then, it presents the importance of communication in this system and why it is necessary to use a common communication protocol and molding function system in the substation automation system.    

Part 2: An introduction to IEC 61850 & how to learn it effectively

A brief history of the standard IEC 61850 Ed.1 & Ed.2, its purpose, and its benefits are presented in this chapter. One problem with learning the IEC 61850 is the variety of documents, topics, and the gap between academics and industry in this area. This part introduces an effective way to learn practical IEC 61850 standards.

Part 3: Overview of the main features of IEC 61850-Part I

This part overviews the OSI model, MMS protocol, and the used devices in the IEC 61850 network. Then, different packets (GOOSE, Report, and Sample Value) and services (for time synchronization, master-slave, client/server, and publisher/subscriber) are presented in this module.

Part 4: Overview of the main features of IEC 61850-Part II

The concept of object-oriented modeling and the data modeling of IEC 61850 are presented in this part. Then different types of GOOSE messages, report control blocks, and SCL files are introduced. This part also presents the connection terminals, communication, and time synchronization ports of a merging unit installed in the process bus lab setup.

Part 5: IEC 61850 data structure and data format-Part I

Initial IEC 61850 settings in DIGSI 5 and the connection between the information routing matrix and IEC 61850 structure editor are presented in this part. The device is opened via OMICRON IEDScout and the data structure of the IED and the relation between them and the IEC 61850 signals in DIGSI 5 are explained. Then the device is exported with different IEC 61850 data formats and different sections of the exported files are explained in detail. To understand the interoperability of IEC 61850, a device from another manufacturer (SEL) is also exported and different sections of this file are explained.

Part 6: IEC 61850 data structure and data format-Part II

Different tools of the IEC 61850 structure editor in DIGSI 5. Editing of the IEC 61850 data model and adding the user-defined LNs are explained too.

Part 7: IEC 61850 station in DIGSI 5 and IEC 61850 System Configurator

A device is added to the IEC station in DIGSI 5 and the station is opened via IEC 61850 System Configurator to explain different parts of the station and the configurator. The connection between each editor in the configurator and the station file is also presented in this part.

Part 8: GOOSE configuration and the publisher/subscriber LNs

The GOOSE configuration between two SIPROTEC 5 devices is presented in this part. The publisher and the subscriber Logical Nodes before the GOOSE configuration and after the GOOSE configuration are compared in the IEC 61850 station files and the information matrix in DIGSI 5.

Part 9: GOOSE simulation via IEDScout

The publisher and subscriber IEDs before and after GOOSE configuration are simulated in the OMICRON IEDScout. The sniffer tool is used to capture the simulated GOOSE of the publisher IED. To show the GOOSE repetition, the value of the GOOSE signal is changed in the IED simulator, and the captured GOOSE after the change is analyzed too.

Part 10: GOOSE configuration and simulation between SIP 5 & SEL relays

An IED from another manufacturer (SEL) is added to the station and the GOOSE configuration between SEL and SIPROTEC IEDs is presented in the IEC 61850 configurator. Then the simulation of the publisher and subscriber IEDs has been done via IEDScout.

Part 11: Time synchronization settings and SNTP configuration

The configuration of the SNTP (Simple Network time protocol) for time synchronization in DIGSI 5 and IEC 61850 system configurator

Part 12: Case study-Part I

In DIGSI 5 training, relays were added and configured based on the diagram of the case study project. This part presents the IEC 61850 configuration in the same case study project. The IEC 61850 and SNTP settings have been entered based on the case study project documents. The table of the communication cables and the diagram of the substation automation architecture is described in this part.

Part 13: Case study-Part II

The report configurations based on the table of reports configured on servers are presented in this part. The signals of the distance IED are added to the data set and a report control block is added to transmit the event to the clients. The report control block settings are also explained in this part.

Download IEC 61850 Configuration Training Package

The UCA is implementing changes to the IEC 61850 certification testing program to follow IEC requirements that only one revision of a standard can be valid at one time. Edition 1 was officially withdrawn by the IEC in December 2012 when Edition 2 became the current revision of the IEC 61850 standard. The UCA has therefore decided to phase out the issuing of Edition 1 only certificate and transition to Edition 2 conformance test certificates. The new Edition 2 conformance tests will include an option for certifying backward compatibility for Edition 1. This will allow new test certificates to cover both Edition 1 and 2 as required by utilities that install new equipment into existing Edition 1 systems or mixed systems (containing Ed. 1 and 2 devices).ย  ย  ย  ย ย 
The end-of-life date for Edition 1 conformance testing and certification is targeted for December 31, 2020. However, the actual date may change depending on when updates to Edition 2 conformance tests are published with procedures for testing Edition 1 backward compatibility. Please read the official press release from the UCA for many more details


Announcement of End-of-Life for IEC 61850 Edition 1 Certification 

The IEC 61850 testing groups, within the UCA IUG, have concluded that the UCA IUG must enforce testing by the IEC position that there is one valid revision of a standard at any given time. Testing to a withdrawn standard is not consistent with the IEC position and would lead to supporting testing and certification of Edition 1, Edition 2, Edition 3, etc. 
Simultaneously long into the future. In the review of the current IEC 61850 QAP Addendum, it has become clear that this was never the intent. Furthermore, the testing groups recognize that an abrupt and immediate transition of testing from one version to another would be very disruptive to all impacted parties. The current IEC 61850 QAP Addendum is lacking adequate guidance for the process of updating the conformance testing procedures in synchronization with the standard. Therefore, to ensure a timely transition to new versions of standards while supporting a stable and growing market for IEC 61850 devices and applications the IEC 61850
QAP Addendum is being updated to define a migration path for how testing procedures are synchronized to new versions of the standards as follows: 

  • A guaranteed minimum period from the publication of a major revision of the IEC 61850 standard. Since the IEC process for releases is a 5-year interval, the current proposal is that conformance testing of a specific major release of 61850 should be guaranteed to be no less than 10 years. It is thought that this guidance allows utility stability for project planning.ย 
  • Upon the publication of a new release, which causes the withdrawal of the previous IEC standard, the conformance test procedures will need to be updated to not only test the conformance to the new standard but also backward compatibility to the previous standard and thereby provide utilities the assurance that new devices can be integrated into older systems protecting utility investment.ย 
  • Once the revised test procedures are available, and the 10-year minimum has been achieved, the UCA Conformance Testing for the older standard would cease
  • Conformance certificates shall indicate if the certificate is being issued based on withdrawn standards.

Edition 1 Conformance Testing is currently outside of these criteria being proposed because the withdrawal date of Edition 1 of the standard was December 2012 and the publication date of Edition 1 was May 2005. The end-of-life for UCA Edition 1 Only Conformance Testing andCertification is targeted for December 31, 2020, and would still require that the backward.  
compatibility testing is available thereafter.   

This announcement is being provided so that the information needed for utility project planning and to protect utility investment in deployments is based upon older versions of the standard. What is being proposed does not mean that older versions of devices would not be available, only that newer versions would be conformance tested to the current version and for compatibility with the older version.
