Relay protection tester

Mga tampok ng produkto:
Flexible combination of voltage and current output, output up to 6 phase voltage and 6 phase current, can be combined to achieve conventional 4 phase voltage, 3 phase current type, 6 phase voltage type, 6 phase current type, at 12 phase output mode, not only compatible with traditional various test methods, but also convenient for three-phase transformer differential test and plant power quick cutting and ready self-injection test.

Operation mode The device is directly connected to the external laptop or desktop computer for operation, maginhawa at mabilis, matatag na pagganap.

The output end of the new high-fidelity linear power amplifier has always adhered to the high-fidelity and high-reliability modular linear power amplifier, rather than the switching type power amplifier, which will not produce high and medium frequency interference on the test site, and ensure the smooth waveform from large current to small current.

The output part of the high-performance host adopts DSP control, which has fast operation speed, strong real-time digital signal processing ability, wide transmission frequency band and high resolution D/A conversion control. The output waveform precision is high, the distortion is small and the linearity is good. A lot of technology and precision components and materials are used, and professional structural design is carried out, so the device is small in size, light in weight, full in function, madaling dalhin, can be started to work, and flow test is very convenient.

It can complete a variety of large-scale and complex calibration work with high degree of automation, and can easily test and scan various protection values, perform fault playback, store test data in real time, display vector images, and print reports online. The 6-phase current facilitates three-phase differential protection testing.

Independent dedicated DC power output with one 110V and 220V dedicated adjustable DC power output.

Interface Complete device with USB communication port, can communicate with computers and other external devices.

Perfect self-protection function Heat dissipation structure design is reasonable, hardware protection measures are reliable and perfect, with power soft start function, software for fault self-diagnosis and output lock and other functions.
