Generally speaking, the VD-Monitor is capable of meeting all test requirements.

The ARTES software also offers a wide range of convenient test monitors which have been specially developed for testing specific protection functions. These test monitors simplify, automate and significantly speed up tests for a range of different types of relays.


The VD-Monitor enables the user to test any protection function by setting the test quantities manually. As well as entering secondary values, primary values can also be used to define all the settings, so it is no longer necessary to go to the trouble of converting the quantities manually. The output signals of the current and voltage amplifiers are set entirely independently from one another as regards amplitude, phase and frequency and are varied independently from one another during tests. In addition, the output signals of certain or all amplifier outputs can also be ramp ascending or descending within the configured range.

Presetting fault loops

Selecting a fault loop facilitates the reproduction of a specific fault. The parameters which can be modified for the selected fault are automatically pre-defined, making it possible to test a two-pole fault taking into account the phase-correct behaviour of the faulted quantities, for example.

Fault definition with symmetrical components

It is also possible to define the test quantities by entering the symmetrical components directly. The output quantities are calculated automatically by the software. Unsymmetrical systems, caused by earth faults, for example, can be defined directly with speed and efficiency.
