Fault Locating
-
Schweitzer Engineering Laboratories, Inc.
The built-in fault-locating methods in SEL devices allow you to quickly identify faults, dispatch crews for repairs, and restore service faster. Traveling-wave fault-locating technology calculates the locations of temporary and permanent faults by measuring the arrival times of the naturally occurring traveling waves caused by a transmission line fault. Accurately detecting these waves requires ultra-high-resolution monitoring, and locating is accurate to within one tower span (±300 m). Impedance-based fault-locating technology calculates fault locations by detecting changes in line impedance as a result of a fault. Impedance-based locating is reliable and accurate to about 2 percent of a line’s total length.

Schweitzer Engineering Laboratories, Inc.
Transmission control systems provide flexible local control and SCADA integration for substation and line protection assets, improving your system’s reliability and efficiency.
-
Product
Remedial Action Schemes
-
Schweitzer Engineering Laboratories, Inc.
SEL’s power management system for utilities uses a remedial action scheme (RAS) in a control system for large geographic regions of interconnected transmission, generation, and loads. This solution is commonly used for the wide-area monitoring, control, and integration of large wind power stations.

Product
Annunciation
-
Schweitzer Engineering Laboratories, Inc.
Annunciators provide local and remote notification to improve situational awareness, efficiency, and safety.
-
Product
Arc-Flash Protection
-
Schweitzer Engineering Laboratories, Inc.
Arc-flash detection technology significantly decreases the time it takes a relay to trip in response to an arc fault, thereby reducing hazardous incident energy. Combining light-sensing technology with fast overcurrent protection provides high-speed arc-flash detection and prevents overtripping for external faults. Arc-flash protection relays work with low- and medium-voltage apparatus and easily coordinate with other devices in utility-, industrial-, and commercial-scale power systems.
