ARTES 460 | 600 test systems
Protection Relay Testing ARTES 460 | 600
ARTES 460 | 600 test systems are used to carry out function tests and tests of configured starting and tripping characteristics, including any automatic reclosing functions of protection devices such as:
They can also be used to test and calibrate power, voltage, current and frequency converters.
With four voltage outputs and six current outputs, even highly complex tests on static, digital and self-powered protection relays can be carried out without additional equipment. The calculation of test quantities and the control of tests are carried out fully automatically.
ARTES 460 | 600 test instruments have been specially developed for harsh transport and operational conditions. Thanks to state-of-the-art technology, the fourth generation of ARTES products have retained the positive features of their predecessors, even though they have more power and more channels. A high level of system integration makes it possible to accommodate these compact systems in a 19“housing while keeping their weight down to a minimum at the same time. 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.
Constant output signals for changing burdens
Even if the burden of the device under test changes during output, constant output signals with very high accuracy are guaranteed. Synthetic signal generation with a powerful signal processor, internal feedback measurements of the output signals in real time and ultra-fast regulation of the amplifiers make this possible and ensure that the signals always correspond exactly to the desired value set for them, even during output.
Wide frequency range for the output of transient signals
The fully electronic amplifiers of ARTES 460 | 600 do not feature any transformers in the outputs. It is therefore possible to generate output signals in a wide frequency range of several kHz. In addition to self-generated signals, records from fault recorder systems can also be output as transient signals.
Immunity to disturbances in the power supply
Immunity to disturbances in the power supply Powerful, wide-range switching mode power supplies safeguard the power supply to the ARTES amplifiers and ensure fault-free operation and constant output signals. Changes to the output quantities are completely eliminated, including inaccuracies and errors resulting from fluctuations in the supply voltage.
