Safe and reliable: light weight (85kg) to avoid the risk of accidents after installation, reduce the primary auxiliary equipment, reduce the risk of equipment failure, and eliminate the potential safety hazards of remote control caused by automation.

Operation function: realize the selective tripping of the short-circuit fault of the overhead line of the distribution network (multi-level precise differential coordination), realize the selective automatic isolation of the single-phase grounding fault of the overhead line of the distribution network (differential coordination), and solve the line loss assessment problem of the overhead line of the distribution network.

Product innovation: the use of high-precision, wide-range electronic sensor to replace the traditional electromagnetic transformer, to achieve measurement/protection/monitoring three-in-one compatibility, sensor and body pole integral sealing process, to achieve deep integration, power mode to solve the power supply PT, modular, standardized design, support hot swap, easy installation.

High degree of intelligence: the equipment does not depend on the master station, and when the line fails, it can accurately and quickly isolate the smallest fault area of the short circuit or single-phase grounding fault; the terminal can independently judge the short-circuit or single-phase grounding fault by itself and issue isolation instructions.
