ARTES RC4 – The Next Generation of Protection Relay Testing

More Performance. More Flexibility. Proven Simplicity.

With the ARTES RC4, KoCoS consistently advances the successful concept of the ARTES RC3. This compact test system enables simple and reliable protection relay testing while offering even greater versatility through more powerful current outputs, an additional voltage output, and new transistor binary outputs.
Designed for field applications, the fully integrated system is housed in a rugged hard-shell case and combines outstanding portability with ease of use and high measurement accuracy. The ARTES RC4 particularly excels in testing grid and system protection systems, such as those used in renewable energy installations.

Key Enhancements at a Glance:

✓ Higher Test Currents
More powerful current outputs provide higher test currents, extending the range of applications—for example, enabling the testing of protection relays with a rated current of 5 A.

✓ Additional Voltage Output
A fourth voltage output offers increased flexibility and supports applications such as earth fault testing.

✓ New Transistor Binary Outputs
Additional transistor binary outputs enable fast simulation of control signals and expand the possibilities for controlling the device under test.

✓ Optimized Binary Inputs
Two separate groups, each featuring two measurement inputs, provide greater flexibility for signal acquisition and analysis.

Proven Strengths Remain

The ARTES RC4 retains all the features that have made the RC3 a trusted solution:

✔ Fully integrated test system in a rugged hard-shell case
✔ Compact design for portable field use
✔ High-precision measurement and amplifier technology
✔ Simple and intuitive Operation
✔ Reliable protection relay testing for on-site applications

With the ARTES RC4, KoCoS combines continuity with innovation—offering users enhanced capabilities without compromising the proven robustness, portability, and ease of use that define the ARTES product family.
