Siemens SIPROTEC

Siemens SIPROTEC is a numeric-protection relay platform you tailor per bay: choose current, voltage, frequency or differential modules, slide them into the rugged housing, set the ANSI/IEC curves via the front keypad or IEC 61850 software; redundant Ethernet, fiber-optic or PROFINET ports let you link to SCADA, synchronize line ends across long feeders and still keep trip times below one cycle.
