Highly precise, portable measuring system for functional tests on various types of protection equipment. Four voltage and six current outputs allow three-phase tests on static and digital relays and on differential protection relays. Analog measurement inputs also make it possible to test and calibrate transducers The device can be operated and controlled either with a PC and the ARTES testing software or alternatively by means of the built-in control panel equipped with a high-resolution, resistive 5" touch screen, function keys and a jog wheel. All signals can be set separately and independently of one another as regards phase, amplitude and frequency. The output values of the current and voltage amplifiers are monitored by means of internal feedback measurements. If the output values do not agree with the setpoint values, a warning is issued to this effect. All outputs also have overload and short-circuit protection. General Frequency range Transient signals Frequency resolution Frequency accuracy Phase angle Phase resolution Phase accuracy Voltage outputs Current outputs Low-level signal outputs Resolution Accuracy Frequency range Transient signals THD Frequency resolution Frequency accuracy Phase angle Phase resolution Phase accuracy Special low-level outputs with very high accuracy make it possible to test protection devices with low-level signal inputs. All signals can be set separately and independently of one another as regards phase, amplitude and frequency. All outputs also have overload and short-circuit protection.
