LY808 Six phase relay protection tester
¿ Flexible combination of voltage and current output
Six phase voltage
and six phase current can be output, which has made it is possiable to be any
combition, such as the output mode of the combination of conventional four phase
current and three-phase current, six phase voltage mode, six phase current mode
and 12 phase output mode. It not only can be compatible with the traditional
way of various tests, but also can conveniently carry out differential test of three-phase
transformer.
¿ Operation mode
The device is
directly connected with a computer or a desktop computer, which is
convenient and efficient and stable performance.
¿ A new hi-fi linear power amplifier
The output port
has always insisted on using the modular linear power amplifier instead of the switching
power amplifier, which has the high fidelity and high reliability function and excellent
performance. High-mid frequency will not be produced to disturb the test, also ensure
the smoothing accuracy of waveform produced by the whole course of the high
current to the tiny current is excellent.
¿ High performance Mainframe
The output part
adopts DSP control, which has fast operation, real-time digital signal
processing capability, wide bandwidth and high resolution D/A conversion
control. The output waveform has the features of high precision, small
distortion and good linearity. With using a large number of advanced technology
and precision components and materials and the structure of professional
design, the device has the features of small volume, light weight, full
function, easy to carry, boot can work, flow test is very convenient.
¿ Powerful software function
It can complete
all kinds of high automatic validation work which is large and complex. It can also
conveniently test and scan protection setting, playback of fault, real-time
store test data, display vector, online print report and so on. Besides, six-phase
current can facilitate the test of three-phase differential protection.
¿ Independent DC power output
An 110V and 220V
adjustable DC power is designed to supply output.
¿ Complete interface
The device with
USB communication port can communicate with the computer and other external
devices.
¿ Perfect self-protection function
With reasonable design
of the heat dissipation structure and the reliable and perfect hardware
protection measures, it has the power soft start function and the software of
the fault self-diagnosis and the output latch function.
