Protection Testing: Ensuring Reliability Electrical Utilities Protection systems play a key role for the safe and reliable operation of today’s electricity power systems. This is relevant for all power system grids in generation, transmission and distribution, industrial, railway, and marine applications. Properly working protection devices help to maintain the safety of the system and to safeguard assets from damage while assisting to ensure security of supply. In order to guarantee reliable operation, protection relays must be tested throughout their life-cycle, from their initial...

Service Providers A protection system in a large industrial plant often incorporates a large number of different devices from various manufacturers. OMICRON provides predefined test templates for many of these different relays and thereby facilitates efficient testing. Hence, downtime in the plant for testing purposes can be kept extremely short. Engineers in industry, who are responsible for the protection equipment, often also take care of a wide range of other tasks. The operation of test equipment which is not used on a daily basis should therefore be as simple as possible. OMICRON test...

OMICRON Automated Testing of Protection Functions For automated testing of protection relays, the Test Universe software provides dedicated test modules for standard protection functions (e.g. Overcurrent, Distance, Differential, etc.). These modules are provided with a graphical user interface showing the relay's characteristic (I/t diagram, impedance plane, etc.) in which the test points are defined and the results of the tests are displayed. Test results are automatically analyzed and assessed by the software to confirm whether the device under test matches the specified performance in...

Efficient Use of Test Plans The multifunctional design of modern numerical protection devices usually requires the use of several different test modules to comprehensively test them. For reasons of efficiency and convenience, it is preferable that the relay parameters do not have to be separately defined for each individual module. In addition, testing with several modules should not result in multiple test reports. For such applications, the patented 1 OMICRON Control Center (OCC) technology offers users a unique solution. Any number of test modules can be combined in one central document...

When providing international commissioning services, clients often expect submission of the test reports in a different language to the one preferred by the test engineer. In the OMICRON operating software, users can choose between 14 different languages. Even when the test report has already been generated, the language can easily be changed for the benefit of the client. For the subsequent processing of the test results, the contents of test reports can be exported to various file formats, such as Microsoft Excel, Microsoft Word, or a database. Moreover, the easy generation of PDF files...
