FAQ

1)In what aspects is the integrated design of the MOEORW-W1900 series microcomputer-based relay protection tester manifested?

Answer: This series of testers adopts an integrated design featuring a built-in industrial control computer and a 10.1-inch true-color LCD display, enabling standalone operation without an external PC. The device integrates multiple interfaces (USB, Ethernet, GPS, Wi-Fi) and power amplifier modules. Its compact structure, small size, and light weight enable immediate operation upon startup, facilitating mobile testing.

2)How does the MOEORW-W1900 series microcomputer-based relay protection tester achieve wireless communication with a PC?

Answer: The tester incorporates a built-in Wi-Fi module supporting two connection modes: Router Mode and Terminal Mode. In Router Mode, the device creates its own hotspot, allowing PCs and other terminals to connect without Ethernet cables. In Terminal Mode, the device can search for and connect to nearby Wi-Fi signals. Once connected, it enables wireless control of the tester's outputs and more flexible data transmission.

3)What formats of fault data files can be imported into the waveform replay function of the MOEORW-W1900 series microprocessor-based relay protection tester?

Answer: The waveform replay function supports importing transient data files in COMTRADE format. This format comprises two core files: CFG (channel configuration file) and DAT (data file). Data can originate from fault recorders or power system transient calculation software (e.g., EMTP). After importing, fault scenarios can be reconstructed and analyze
