High-Performance SEL-787 Transformer Protection Relays from Schweitzer Provide Protection
Melissa Larson | March 4, 2015
With the newly released SEL-787 Relays from Schweitzer, users can now protect transformers in up to four-terminal differential applications and standardize on a single transformer protection platform, reducing business and operation costs. These relays (SEL-787-3E, -3S, and -4X) offer the following benefits:
• Protection for transformers in 2-, 3-, or 4-terminal applications using one relay family, keeping schematics simple and minimizing the learning curve,
• Expanded capability to apply current differential, voltage, frequency, and/or thermal-based protection functions,
• Sensitive detection of internal faults near the grounded neutral with as many as three restrictive earth fault (REF) elements.
In addition to many protection benefits, the new SEL-787 Relays include Spanish language support for the ACSELERATOR Software, front-panel overlay, and relay scripting. Spanish-speaking engineers and technicians will be able to quickly configure and use the relays.
