Useful addition to the ARTES product line

With the ARTES 460 and ARTES 600, two very capable test systems are offered which provide almost all functions for protective relay testing. Where does the ARTES RC3 come in here and how does it differ from the other systems? 

ARTES RC3 has some features and advantages that are particularly useful for certain applications and target groups.


Renewable energy generation plants, especially wind turbines and solar parks, have become more and more important worldwide in recent years. In these plants there are special relays, such as the Q-V protection, which have to be checked regularly.

Energy suppliers and grid operators are often not in a position to comply with the tests due to the large number of installations and are often not the operators of these plants. The testing of protective relays is therefore more and more carried out by service companies.


The aim of developing the ARTES RC3 was to take into account the special requirements of these service providers or service companies. The new RC3 is also suitable for almost all other protection tests in the field of electrical power supply.

There are certainly some limitations due to the number of current amplifiers when testing differential protection relays. However, tests of frequency, voltage, overcurrent, distance protection and many other protection relays can be carried out just as well and efficiently with the ARTES RC3. In addition to the local operation, the new ARTES 5 software with all its special functions is also available for the RC3.


But what are the criteria that are especially important to service companies? Due to the number of test systems required, price is certainly a very important criterion for many customers. What they are looking for is a cost-effective solution that provides all the necessary functions but does not contain additional, expensive features that are not required for the specific application.

Another important point is the robustness of the device. The environment in which the tests are carried out often does not meet that of many conventional plants. Harsh environmental conditions are often encountered in regenerative energy generation plants. The high demands on robustness, reliability and durability were particularly taken into account in the development of the ARTES RC3. The RC3 is very well protected due to its design in an extremely robust hard-shell case.


And last but not least, the possibility of being able to carry out tests completely without a PC is often very useful for tests in regenerative energy generation plants. Even the test results of the RC3 can be read out via smartphone without a PC using the new ARTES app and clearly displayed in a test report. This report can also be sent by e-mail as a PDF file directly on site. 



The ARTES RC3 should therefore not be seen primarily as a replacement for the ARTES 460 or ARTES 600. Rather, it complements the product line in a meaningful way and offers exactly what a large customer base specifically needs.
