Why the Siemens Siprotec 7SJ62 Protection Relay is Essential

The Siprotec 7SJ62 protection relay is a versatile solution for protecting high and medium-voltage networks. It is suitable for systems with various neutral point configurations, including grounded, low-resistance grounded, isolated, or compensated setups. Additionally, it is well-suited for motor protection, accommodating asynchronous machines of all sizes.

It is possible to use the Siprotec 7SJ62 Protection Relay to secure high and medium-voltage networks with earthed (grounded), low-resistance earthed, isolated, or compensated neutral points. Asynchronous machines of different sizes can benefit from the motor protection offered by the SIPROTEC 4 and 7SJ62 protection relays. In addition to transformer differential protection, the relay does all backup protection tasks. 7SJ62 has “flexible protection functions”. Depending on specific needs, up to 20 protective features can be incorporated. Therefore, it is possible to implement protections like reverse power or rate-of-frequency-change protection. The circuit-breaker and automation features are controlled by the relay. 

For example, the user can automate switchgear (interlocking) by implementing their own functions using integrated programmable logic (CFC).
