This portable single-phase relay protection tester is a lightweight testing device developed for outdoor small substations and distribution operation and maintenance sites. It focuses on portability and easy operation, designed for quick on-site calibration of single-phase overcurrent, overvoltage and differential relay protection devices. It solves the pain point that traditional large-scale testers are difficult to move, and adapts to operation and maintenance scenarios without fixed power supplies in the wild. Equipped with a lightweight alloy shell and built-in rechargeable lithium battery, it supports offline testing, and can quickly generate standard test reports with supporting professional testing software. It is suitable for daily maintenance of township power grids, small enterprise distribution rooms and other scenarios, helping power operation and maintenance personnel quickly complete protection device calibration and fault troubleshooting.
