Applications Highly precise, portable measuring system for functional tests on various types of protection equipment. Four voltage outputs and six current outputs which can provide particularly high output power allow three-phase tests on static, digital and self-powered relays as well as 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. Sources 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. Frequency range Transient signals Frequency resolution Frequency accuracy Phase angle Phase resolution Phase accuracy Voltage outputs Current outputs Resolution 1 mA Low-level signal outputs 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.
