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 ...

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 ...

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 (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 ...

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