Six-phase Relay Protection Test Instrument

● Flexible combination of voltage and current output The output reaches 6-phase voltage and 6-phase current, which can be arbitrarily combined to realize conventional 4-phase voltage and 3-phase current, 6-phase voltage, 6-phase current, and 12-phase output modes. It is compatible with various traditional test methods and can also conveniently carry out three-phase transformer differential test and factory power fast cut and standby automatic test.

● Operation mode The device is directly connected to a laptop or desktop for operation, which is convenient and fast with stable performance.

● New high-fidelity linear power amplifier The output end has always insisted on using high-fidelity, high-reliability modular linear power amplifiers instead of switch-type power amplifiers, with excellent performance. It will not cause high and medium frequency interference to the test site, and ensures that the waveform is smooth and accurate from large current to small current.

● High-performance host The output part adopts DSP control, with fast computing speed, strong real-time digital signal processing capability, wide transmission bandwidth, and high-resolution D/A conversion control. The output waveform has high accuracy, small distortion and good linearity. A large number of advanced technologies and precision components and materials are adopted, and professional structural design is carried out. Therefore, the device is small in size, light in weight, full in function, easy to carry, can work as soon as it is turned on, and flow test is very convenient.

● Powerful software functions It can complete various large-scale and complex verification tasks with high degree of automation, perform fault playback, store test data in real time, display vector diagrams, print reports online, etc. 6-phase current can facilitate three-phase differential protection testing.

● Independent dedicated DC power output It is equipped with a 110V and 220V dedicated adjustable DC power output.

● Complete interface The device has a USB communication port, which can communicate with computers and other external devices.

Perfect self-protection function The heat dissipation structure is reasonably designed, the hardware protection measures are reliable and complete, and it has power soft start function, software self-diagnosis of faults and output locking functions.
