The device adopts a built-in high-precision signal source module, supporting three-phase synchronous output to test complex protection devices such as three-phase differential protection and distance protection at the same time. It is equipped with a 10-inch touch screen and a graphical operation interface, with a built-in 64GB storage capacity to store massive test data. It supports Bluetooth 5.0 wireless communication, enabling synchronous transmission of test data to the background management system without data cables. It has over-temperature and over-current protection mechanisms to ensure testing safety, and supports one-click automatic testing of preset protection devices to simplify operation steps.

Detailed technical parameters: three-phase synchronous testing, per-phase output AC current 0~40A, DC current 0~30A; per-phase output AC voltage 0~200V, DC voltage 0~150V; accuracy grade reaches Class 0.2, supporting 0~30 times harmonic output and transient fault signal simulation; the device dimensions are 450*320*200mm, net weight 8.2kg, supports AC 220V external power supply or 24V DC backup power supply, equipped with USB, RS232 and Bluetooth 5.0 communication interfaces, supports data export in MATLAB format, and has built-in Chinese and English bilingual operation interfaces.

It is suitable for full-item verification and fault troubleshooting of relay protection devices in 35kV~110kV substations and regional power grid dispatching centers. It can test various complex protection devices such as differential protection, distance protection and zero-sequence protection, and is suitable for professional power operation and maintenance teams, power maintenance companies for on-site use, and can also be used as mobile detection equipment for power inspection institutions.
