SIPROTEC 7SK80 - Motor protection

4xI 0/3xV, small and medium-sized motors

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.

Features

The SIPROTEC 7SK80 features “flexible 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 programmable 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-defined messages.

应用

The SIPROTEC 7SK80 unit is a numerical motor protection relay that can perform control and monitoring functions and therefore provide the user with a cost-effective platform for power system management, that ensures reliable supply of electrical power to the customers. The ergonomic design makes control easy from the relay front panel. A large, easyto-read display was a key design factor.

Control

The integrated control function permits control of disconnect devices, grounding switches or circuit-breakers through the integrated operator panel, binary inputs, DIGSI 4 or the control or automation system (e.g. SICAM).

Programmable logic

The integrated logic characteristics (CFC) allow the user to add own functions for automation of switchgear (e.g. interlocking) or switching sequence. The user can also generate user-defi ned messages. This functionality can form the base to create extremely flexible transfer schemes. Operational measured value Extensive measured values (e.g. I, V), metered values (e.g.Wp,Wq) and limit values (e.g. for voltage, frequency) provide improved system management.

Operational indication

Event logs, trip logs, fault records and statistics documents are stored in the relay to provide the user or operator with all the key data required to operate modern substations.

Motor protection

The SIPROTEC 7SK80 device is specifically designed to protect induction-type asynchronous motors.

Line protection

SIPROTEC 7SK80 units can be used for line protection of high and medium-voltage networks with grounded, low-resistance grounded, isolated or a compensated neutral point.

Transformer protection

The SIPROTEC 7SK80 device provides all the functions for backup protection for transformer differential protection. The in suppression effectively prevents unwanted trips that can be caused by in currents.

Backup protection

As a backup protection the SIPROTEC 7SK80 devices are universally applicable.

Switchgear cubicles for high / medium voltage

All units are designed specifically to meet the requirements of high / medium-voltage applications. In general, no separate measuring instruments (e.g., for current, voltage, frequency, …) or additional control components are necessary.
