Schweitzer Engineering Laboratories has released the SEL-T400L Time-Domain Line Protection—the world’s first traveling-wave microprocessor-based relay. It detects power system faults and sends a trip ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal operating conditions that overload devices and breakers cannot see, guiding ...

To be competitive, some electrical contractors often supply low-voltage (LV) service entrance switchboards and switchgear that meet the minimum safety requirements of the National Electrical Code (NEC ...

AREVA Transmission & Distribution has just launched a cost-efficient and user-friendly family of advanced numerical distance and differential protection relays in its MiCOM range AREVA Transmission & ...

Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...
