The high impedance principle provides a unit protection used in restricted earth fault, busbar and connections protection schemes. It ensures sensitive, high speed operation for internal faults and guaranteed stability during external faults. By incorporating the latest technology, including IEC 61850, we have designed a dedicated High Impedance Relay that offers increased protection functionality and performance, whilst retaining the familiar look and feel of the Reyrolle product range. IEC 61850 The IEC 61850 protocol implementation on the Ethernet EN100 module, utilised on the Reyrolle products, benefits from the knowledge and expertise of Siemens who are world leaders in this field with several years service experience gained through the large number of installed Siprotec relays. Based on decades of experience in High Impedance Protection SPDL have developed the 7SR23 DAD relay which provides comprehensive, configurable high impedance protections with enhanced functionality and performance. Relay functionality is accessed via our familiar user friendly interface.

What is High Impedance Protection? Proven, straightforward, high performance protection! The high impedance principle provides a unit protection used in restricted earth fault, busbar and connections protection schemes. It ensures sensitive, high speed operation for internal faults and guaranteed stability during external faults.
By incorporating the latest technology, including IEC 61850, we have designed a dedicated High Impedance Relay that offers increased protection functionality and performance, whilst retaining the familiar look and feel of the Reyrolle product range.
IEC 61850The IEC 61850 protocol implementation on the Ethernet EN100 module, utilised on the Reyrolle products, benefits from the knowledge and expertise of Siemens who are world leaders in this field with several years service experience gained through the large number of installed Siprotec relays.
Based on decades of experience in High Impedance Protection SPDL have developed the 7SR23 DAD relay which provides comprehensive, configurable high impedance protections with enhanced functionality and performance. Relay functionality is accessed via our familiar user friendly interface.
