Install current monitoring sensors without interrupting service.

Apply the SEL-FLT and SEL-FLR Fault and Load Transmitter and Receiver System to improve distribution system reliability metrics and customer satisfaction. The SEL-FLT Fault and Load Transmitter operates using 900 MHz wireless sensors that continuously monitor the line for faults while providing load data with 2 percent accuracy to the SEL-FLR Fault and Load Receiver, with a range of up to 10 miles. Speed up system restoration by pinpointing faults and knowing where to send repair crews. Accurate and real-time load monitoring enables improved switching decisions, since operators confidently know which viable alternate feeders are available to pick up the impacted customers.

This distribution automation sensor stores load data and monitors the distribution line for loss of current or fault events. Reports are transmitted to an access point on a communications network using an integrated radio.

Apply the SEL-311C Relay for complete protection, monitoring, and control of transmission lines.

The SEL-351 Relay has built-in Ethernet and IEEE C37.118 synchrophasors, and is ideal for directional overcurrent applications. Optional Mirrored Bits communications and power quality monitoring add flexibility to solutions. The SEL-351 is the protection standard for utility and industrial electrical systems around the world.

Protect and control any two-, three-, or four-winding power transformer with the SEL-387, which provides thermal and through-fault monitoring, and with SELogic Control Equations, can detect breaker failure.

Monitor and Control Critical Substation Apparatus With One Powerful Package

The SEL-734B provides advanced monitoring and control capabilities for applications such as three-phase capacitor bank control and feeder automation.

The SEL-787 Relay is a versatile, two-winding current differential relay that protects industrial transformers. Monitor transformer health with cumulative through-fault current recording, and for the first time in the industry, automatically check and generate differential compensation settings with the Commissioning Assistant Software.

The SEL-2411 offers rugged I/O for SCADA, PLC, monitoring, and control in harsh physical and electrical environments.

The SEL-2411P Pump Automation Controller is a complete preconfigured, SCADA-ready system for control and monitoring of water and wastewater pump applications.

The SEL-2414 Transformer Monitor provides an exceptional combination of monitoring, control, and communications in a compact package.

Although a trip coil monitor may be a small part of a protection system, its misoperation can be a huge problem and can cost utilities time and money. The SEL-2652 brings increased reliability and versatility to trip coil monitoring, giving you peace of mind that your circuit breakers will operate when necessary.

Avoid exposing personnel to hazardous conditions by enabling them to control and monitor equipment from their trucks or other safe locations.

synchroWAVe Event can plot relay oscillography, display phasors, and monitor digital status.
