The SIPROTEC 7SA522 relay provides full-scheme distance protection and incorporates all functions usually required for the protection of a power line. The relay is designed to provide fast and selective fault clearance on transmission and subtransmission cables and overhead lines with or without series capacitor compensation. The power system star point can be solid or resistance grounded (earthed), resonant-earthed via Peterson coil or isolated. The SIPROTEC 7SA522 is suitable for single-pole and three-pole tripping applications with and without tele (pilot) protection schemes.
The SIPROTEC 7SA522 incorporates several protective functions usually required for transmission line protection.

The SIPROTEC 4 7SJ61 relays can be used for line protection of high and medium voltage networks with earthed (grounded), low-resistance earthed, isolated or compensated neutral point. When protecting motors, the SIPROTEC 4 7SJ61 is suitable for asynchronous machines of all sizes. The relay performs all functions of backup protection supplementary to transformer differential protection ???
The relay provides control of the circuit breaker, further switching devices and automation functions. The integrated programmable logic (CFC) allows the user to implement their own functions, e. g. for the automation of switchgear (interlocking). The user is also allowed to generate user-defined messages. The flexible communication interfaces are open for modern communication architectures with control systems.

Electric arcs are among the most dreaded fault scenarios in power supply engineering. They can be caused by a multitude of factors, such as aging of the insulation, environmental conditions as well as operating errors. Electric arcs can cause heavy damage to switchgear and present a serious hazard to operating personnel.
The SIPROTEC 5 arc protection detects electric arcs through an optical sensor. Arcs are detected reliably and quickly as they develop, and the protective device can trip immediately and without delay times.The arc protection module is part of the new SIPROTEC 5 series of modular, flexible and intelligent bay devices and can be used in the following device types:

The 7SD5 relay provides full scheme differential protection and incorporates all functions usually required for the protection of power lines. It is designed for all power and distribution levels and protects lines with two up to six line ends. The relay is designed to provide high-speed and phase-selective fault clearance. The relay uses fiber-optic cables or digital communication networks to exchange telegrams and includes special features for the use in multiplexed communication networks. Also, pilot wires connections can be used with an external converter. This contributes toward improved reliability and availability of the electrical power system. The relay is suitable for single and three-phase tripping applications for two up to six line ends.
The 7SD5 has the following features:

Siemens SIPROTEC 7SJ66 Multifunction Protection Relay is a numerical protection, control, and monitoring device. SIPROTEC 7SJ66 is featuring the "flexible protection functions". Up to 20 protection functions can be added to Siprotec 7SJ66 multifunction relay according to individual requirements. Thus, for example, a rate-of-frequency-change protection or reverse power protection can be implemented. The relay provides control of the circuit-breaker, further switching devices and automation functions. The integrated Graphical logic editor (CFC) allows the user to implement its own functions, e. g. for the automation of switchgear (interlocking). The communication interfaces support the easy integration into modern communication networks.
SIPROTEC 7SJ66 Multifunction protection:
Control functions/programmable logic
Monitoring functions
