In a large number of new and expanded substation projects, relay protection, as the first line of defense for power grid safety, must rely on professional testing instruments to complete constant value verification and logical group transmission for operation handover, annual preventive maintenance, and protection device renovation and upgrading.

And engineering teams often encounter several types of problems:

1. Four-phase testers have complicated wiring processes that are prone to errors; imported equipment is expensive and has long lead times.

2. 2. Unexpected power outages can easily cause system crashes, delaying maintenance.

3. On-site calibration requires opening the cover to adjust potentiometers, which is difficult for non-manufacturer personnel to operate.

4. Protection devices are diverse, requiring advanced simulations such as harmonics, oscillations, and waveform playback.

5. Older equipment has weak report output, resulting in a large workload for compiling and accepting data later.

★Important selection tips

• High voltage and high current connection is strictly prohibited.

• High current output is time-limited; do not exceed the time limit.

• Auxiliary power supply is for protection devices only; do not use it as an operating power supply.

• Default AC220V; AC110V requires ordering specification.

• Do not install third-party software; save data to D drive or USB drive.

▎Product highlights:

• Six-phase output, enabling complex protection tests without splicing.

• DSP+FPGA platform, 16-bit high precision, supports harmonic, waveform recording, and oscillation simulation.

• Built-in industrial PC + Windows recovery system, preventing system crashes; 10.4-inch screen, integrated keyboard and mouse, compatible with external laptops.

• Fully automatic software calibration, no need to open the cover; built-in DC power supply for protection devices.

• Overcurrent, overvoltage, and overheat protection; high current time limit; open circuit current circuit prevents damage; panel indicator lights indicate abnormalities.

• Compatible with international protection and relay standards; reports are stored locally and exported to USB flash drive, meeting acceptance archiving requirements.
