Performance characteristics
1. Flexible combination of voltage and current output: output up to
4-phase voltage and 3-phase current, can be arbitrarily combined to
achieve conventional 4-phase voltage and 3-phase current mode
output, which can not only be compatible with traditional test
methods, but also be convenient for three-phase transformer
differential test and auxiliary power quick-cut and standby
self-switching test.
2. Operating mode: The device is directly connected to a laptop or
desktop computer for operation, which is convenient, fast and
stable.
3. New type of high fidelity linear power amplifier: the output
terminal has always insisted on the use of high fidelity, high
reliability modular linear power amplifier, rather than switching
power amplifier, with excellent performance. It will not cause high
and intermediate frequency interference to the test site, and
ensures good waveform smoothing accuracy throughout the whole
process from large current to small current.
4. High performance host: The output part is controlled by DSP,
which has fast operation speed, strong real-time digital signal
processing ability, wide transmission bandwidth and high resolution
D/A conversion. The output waveform has high precision, small
distortion and good linearity. A large number of advanced
technology and precise component materials are adopted, and the
specialized structure design is carried out. Therefore, the device
is small in size, light in weight, full in function, easy to carry,
and can work on start-up and flow test is very convenient.
5. The software has powerful functions: it can complete all kinds
of large-scale and complex checking work with high automation, test
and scan all kinds of protection settings conveniently, perform
fault playback, store test data in real time, display vector
diagram, print report online, etc. It is convenient to test
three-phase differential protection.
6. It has an independent special DC power supply output: it has a
110V and 220V special DC power supply output.
7. Complete interface: The device has a USB communication port,
which can communicate with computers and other external devices.
8. Perfect self-protection function: reasonable heat dissipation
structure design, reliable and perfect hardware protection
measures, power supply soft start function, software self-diagnosis
of faults and output locking function.
