Built in industrial computer, 10.4 inch LCD screen, both offline operation, can also be connected to the notebook operation.
The configuration of the 12 D/A, 6U+6I, and the output mode of the utility model can effectively solve the debugging problems of various differential protection, the automatic switching device and the fast cutting device.
Working power supply AC and DC power supply, more flexible and convenient.
Un and In are completely isolated from each other, and meet the requirements of power system safety.
The utility model has the function of mining, which can not only detect the output signal, but also detect the external signal.
With the power supply fault 380VAC, voltage source short circuit, current source open circuit, instrument overheating, online failure alarm protection function.
The upper and lower computer adopts the way of network communication, which is faster and more stable than the COM and USB communication mode.
Frequency synchronization the one and only, without any external device, can control more than one meter output at the same time without any changes can be composed of a system of infinitely many analog and mutual stable output, it is convenient for a variety of complex dynamic simulation test, especially suitable for scientific research units, the electric power training center two, equipment inspection and supervision organization, teaching base, power department and other units of the demand.
But the built-in GPS module (optional), optical fiber (HF) on both sides of the line protection synchronization test.
With a quick out of the interface (response time is less than 100 microseconds), more accurate time test.
National original grid synchronization function, can be directly incorporated into the grid system for online testing, closer to reality.
Software testing function rich, can test the voltage, current, frequency, time, intermediate, impedance, differential relay and other line protection, bus protection, transformer protection and generator transformer protection relay protection.
Test software free upgrade, PC support for all versions of Windows operating system.
