Detect blown fuses or interruptions of the potential transformer circuit with the LOP element in the SEL-701. “Adding Acselerator software support to the SEL-701 Relay makes it easier to keep all ...

This is in contrast to most relays on the market today, which provide protection for only one or the other. The SEL-710-5 Relay also detects arc-flash events, with a typical response time of 4 ...

Schweitzer Engineering Laboratories, Inc. (SEL) added an optional touchscreen display to the SEL-751 Feeder Protection Relay that allows users to easily navigate settings options and create custom bay ...

Schweitzer Engineering Laboratories (SEL) 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 ...

The SEL-9220 mounts directly to the EIA-485 port on the relay connector that is normally occupied by a compression terminal block. It converts the EIA-485 port to a dedicated point-to-point ...
