Distribution Automation
Breaker position, bus current and residual-current sensing for MV/LV switchgear and ring main units, plus over-current protection and energy metering.
Distribution Automation
Distribution automation is about knowing the state and isolating the fault. Breaker position, bus current and residual current are the three most basic measurements — get any of them wrong and you risk a spurious trip or a failure to operate.
RJMICRO Hall latches sense breaker and disconnector position, linear and differential Hall current sensors measure bus current, residual current and CT signals, and low-quiescent-current LDOs power battery backup and communication modules in ring main units.
Systems and scenarios covered
