ARTES Automatic Relay Test Systems

More than 20 years of experience in developing and manufacturing automatic relay test systems have gone into creating the fourth generation of ARTES test instruments. Back in 1996, KoCoS was the first company to present Windows-based testing software for controlling and operating test equipment and the company continues to play a pioneering role in the design of clearly structured and ergonomic user interfaces today.

ARTES 460 | 600 test systems are practical solutions which can cope with just about any relay testing task.



Compact test system for three-phase tests, can be used as a universal tool for testing digital protection relays.



Compact test system for highly complex test tasks. 4 voltage outputs and 6 current outputs which can provide particularly high output power allow three-phase tests on static, digital and self-powered relays.


System description

ARTES 460 | 600 test instruments have been specially developed for harsh transport and operational conditions. A very effective cooling system and automatic fan control reduce the noise generated by the test instruments to a barely perceptible level.


Current and voltage amplifiers

ARTES 460 | 600 test systems have four voltage outputs and six current outputs. The test quantities are monitored constantly by means of an internal feedback measurement of the output signals.


Test currents of up to 96 A with parallel operation

The current amplifiers of the ARTES 600 provide a maximum test current of 6 x 32 A. Parallel operation of the current outputs allows output of up to 3 x 64 A for 3-phase applications and up to 96 A for 1-phase applications.


Equipment and handling

ARTES 460 | 600 test instruments can be operated and controlled with the aid of a PC and the ARTES testing software or with the built-in control panel. The control panel features a high-resolution, resistive 3.5“ or 5“ touch screen, function keys and a jog wheel.

The USB, Ethernet and Wi-Fi (ARTES 600) interfaces allow direct connection to PCs or any network.
