Highly precise, portable measuring system for functional tests on various types of protection equipment. Three voltage and three current outputs allow three-phase tests on static and digital protection relays. 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 quantities of the current and voltage amplifiers are monitored by means of internal feedback measurements. If the output quantities do not agree with the setpoint values, a warning is issued to this effect. All outputs also have overload and short-circuit protection.
