SIPROTEC COMPACT

They are perfectly suited for protection in distribution and industrial systems that provide a wide range of functions in a compact, compact, space-saving compact enclosure with minimal need for low compact space.

This group of relays, both as primary protection and as backup protection, can functionally provide protection for any conceivable error, and can even perform more tasks such as control, automation and monitoring functions. Do

Attributes:

  • Compact and compact design
  • Easy installation without the need for special tools
  • Six-line display
  • Eight freely selectable LEDs
  • Not the key to operating freely variables
  • Programmable voltage and voltage terminal blocks
  • USB interface mounted on the front
  • The battery can be disassembled from the front panel
  • Two interfaces for remote access
  • Customizable logic (CFC) and flexible protection functions
  • Binary input voltage adjustable threshold with DIGSI
  • Adjustable secondary current with conversion ratio (1 A / 5 A)

SIPROTEC COMPACT

7SA64

۷SA6 Protection Relay is a remote relay used for protection, control and automation with a graphical display based on the SIPROTEC 4 system. A very important case is the high flexibility of this relay, which makes it applicable at all voltage levels.

7SA61

Series SJ61 / 62/63/64 Series SIPROTEC 4 relays are numerical protection relays capable of controlling and monitoring functions that provide cost-effective management of the power system. These relays have several protection modules, including motor protection, overload and power, breaker failure, Under / Over voltage, Under / Over frequency. , Auto-Reclosure, Fault Locator, Lockout. , Overcurrent and Earth Fault Protection, etc.

6MD63

This relay is a simple, flexible control relay that is ideal for medium voltage high voltage and high voltage substations. Designed with the same SIPROTEC 4 generation, it uses a simple DIGSI 4 configuration tool and a large graphical display with a keypad and an alarm list display. It should be noted that the operator panel is flexible enough that it can be installed separately from the relay and that the relay can be connected and optimized to three switches with three states.

7SJ66

This relay is a numerical protection, control and surveillance device that includes “flexible protective functions” and can accommodate up to 6 protective functions depending on individual needs. This relay can control power switches, switching devices, and more automation functions Condoniz integrated graphical logic editor (CFC) allows the user to implement their functions

7SJ64

This relay can be used as a protection and monitoring control relay for distribution feeders and transmission lines in the Venice Voltage in networks that are either directly or resistively grounded, as well as in networks not grounded. This relay is suitable for radial or loop networks and for lines with single or multi-terminal feeds and includes “flexible protection functions” which can be added to the protection function as required. It should be noted that flexible communication interfaces have open source architecture with control systems.
