Description
Description
The SIPROTEC 7SK80 is a multi-functional motor protection
relay. It is designed for protection of asynchronous motors
of all sizes. The relays have all the required functions to be
applied as a backup relay to a transformer differential relay.
The SIPROTEC 7SK80 features “fl exible protection functions”.
Up to 20 additional protection functions can be created by
the user.
Therefore protection of change for frequency or reverse
power protection can be realized, for example.
The relay provides circuit-breaker control, further switching
devices and automation functions. The integrated program-
mable logic (CFC) allows the user to add own functions, e.g.
for the automation of switchgear (interlocking). The user is
also allowed to generate user-defi ned messages.
Highlights
• Pluggable current and voltage terminals
• Binary input thresholds settable using DIGSI (3 stages)
• Secondary current transformer values (1 A / 5 A) settable
using DIGSI
• 9 programmable function keys
• 6-line display
• Buffer battery exchangeable from the front
• USB front port
• 2 additional communication ports
• Integrated switch for low-cost and redundant optical
Ethernet rings
• Ethernet redundancy protocols RSTP, PRP and HSR for
highest availability
• Relay-to-relay communication through Ethernet with
IEC 61850 GOOSE
• Millisecond-accurate time synchronization through
Ethernet with SNTP (over Port A or Port B)
• Number of binary binputs and inary outputs by connec-
tion from up to two SICAM I / O-Units extendable.
