Secondary System Tester

HD2012 Microcomputer Relay Protection Tester

Performance characteristics

Flexible combination of voltage and current output The output can reach 6-phase voltage and 6-phase current, which can be combined to achieve conventional 4-phase voltage, 3-phase current type, 6-phase voltage type, 6-phase current type, and 12-phase output mode, which can be compatible with traditional output modes. This kind of test method can also conveniently carry out the three-phase transformer differential test and the factory power quick cut and standby automatic switch test.

Operation mode The device is directly connected to a laptop or desktop computer for operation, which is convenient and fast, and has 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 switching power amplifiers, with excellent performance. It will not produce high- and intermediate-frequency interference to the test site, and it ensures that the waveform is smooth and accurate in the whole process from large current to small current.

The output part of the high-performance host adopts DSP control, with fast calculation speed, strong real-time digital signal processing ability, wide transmission frequency, and high-resolution D/A conversion control. The output waveform has high precision, low distortion and good linearity. Adopting a large number of advanced technology and precision components and materials, and carrying out a professional structural design, the device is small in size, light in weight, full-featured, easy to carry, and it can work after booting, and the flow test is very convenient.

The software has powerful functions. It can complete various large-scale and complex calibration tasks with a high degree of automation. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online. The 6-phase current can facilitate the three-phase differential protection test, and the 12-phase output can be used for the automatic switching test of the factory power supply.

It has an independent dedicated DC power output. There is a 110V and 220V dedicated adjustable DC power output.

Complete interface The device has an RS232 port, which can communicate with computers and other external devices.
