Siemens SIPROTEC 5 7SX82 Universal Protection Relay
Siemens SIPROTEC 5 7SX82 Universal Protection Relay Suppliers,Exporters in India
ARP IMPEX is a supplier and exporter of Siemens SIPROTEC 5 7SX82 Universal Protection Relays in India. We handle requirements for medium-voltage switchgear, feeder protection panels, industrial substations, line protection projects and replacement of existing Siemens numerical relays.
The Siemens SIPROTEC 7SX82 is a configurable protection and control relay for medium-voltage distribution networks. It can cover several applications within one platform, including feeder protection, overhead-line and cable protection, motor protection and backup protection.
Depending on the ordered configuration, the relay can provide overcurrent, earth-fault, distance, line differential, voltage, frequency and motor protection functions. Circuit-breaker control, switchgear interlocking, event recording and substation communication can also be included.
This flexibility allows panel builders and project engineers to use the 7SX82 across different protection panels instead of maintaining several unrelated relay models. The required functions are selected according to the application and the ordered Siemens configuration.
The relay supports Siemens DIGSI 5 for settings, engineering and commissioning. IEC 61850 communication is available for integration with modern substation automation systems. The communication modules, number of inputs and outputs, and enabled protection functions can vary between article numbers.
Buyers looking for Siemens SIPROTEC 5 7SX82 Relays can share the complete Siemens article number for price, availability and export quotation.

Main Protection Functions
Depending on the ordered configuration, the Siemens SIPROTEC 7SX82 can provide:
- Directional and non-directional overcurrent protection
- Earth-fault protection
- Sensitive earth-fault protection
- Distance protection for overhead lines and cables
- Line differential protection
- Motor overload and short-circuit protection
- Undervoltage and overvoltage protection
- Underfrequency and overfrequency protection
- Load-shedding functions
- Synchrocheck and switching supervision
- Circuit-breaker failure protection
- Capacitor-bank protection on applicable configurations
- Arc protection
- Backup protection for transformers and generators
The 7SX82 should be selected according to the actual protection application. A relay configured for feeder overcurrent protection may not have the same hardware or enabled functions as a model used for line differential or motor protection.
