ARTES II - Precision Measurement Techniques for Relay Testing
Applications

The test modules of the latest ARTES II generation have been optimally designed for functional testing, and especially for the testing of the configured excitation and trigger response characteristics (including automatic reclose functions) of a wide range of protection devices, such as:
- distance protection relays,
- differential protection relays,
- overcurrent relays,
- f, V relays.
In addition, the ARTES II systems can be used to test and calibrate power, voltage, current and frequency transducers.
All the test systems are controlled by an external, standard PC. A variety of software modules, known as test monitors, are available for the purposes of test performance and evaluation. As a result, the models of the ARTES II generation are universal test systems providing the ideal solution for a wide variety of tasks beyond the scope of protection relay testing alone.

The three-phase test systems can, for example, also be used as convenient three-phase function generators which are freely configurable in amplitude, frequency and phase angle. Even flicker signals can be generated.
In addition to static tests, ARTES II can also carry out dynamic tests during the course of which the amplitudes of the current and the voltage, the frequency and the phase angle can be adjusted automatically and simultaneously within a broad range. The test values for fault-specific tests are calculated fully automatically for different fault types. By taking the configured fault and source impedances into account, protection devices can be tested under realistic conditions.
In addition to the binary measurement inputs, ARTES 440 II also has eight analog measurement inputs which can be used to record currents and voltages in a similar way to a disturbance recorder. During tests these records can then be played back again via the hardware as transient waveforms.
