Sifang Huaneng CSF206L Line Protection Device
The CSF206L Line Protection and Control Device is used for the protection of 110kV and below transmission lines or station service transformers. The device is equipped with RS232 and LonWorks or Ethernet communication interfaces, enabling connection to monitoring systems to achieve *** substation integrated automation systems. A timed *** self-checking system significantly enhances protection reliability. Applications include power systems as well as motive power systems in industries such as transportation, metallurgy, energy, and chemical engineering, specifically for 110kV and below lines or station service transformer protection.

Main Features:

◆ Protection functions are *** reliable and flexibly configurable.

◆ *** Measures three-phase current, three-phase voltage, zero-sequence current, zero-sequence voltage, and synchronizing voltage.

◆ Accurately calculates power and frequency.

◆ Telemetry, teleindication, and telepulse.

◆ 128×64 dot large LCD with full Chinese character display.

◆ User-friendly Chinese Windows-style interface.

◆ Simple and convenient Sifang keyboard.

◆ Four LED indicators display four typical operating statuses.

◆ Real-time display of measured values for current, voltage, power, and frequency.

◆ Displays typical teleindication values.

◆ Capable of storing up to 5 sets of protection settings.

◆ Clear fault information indication.

◆ Allows local or remote access via communication network to measurement values, settings, operation reports, etc.

◆ Suitable for both integrated and non-integrated automation systems.

◆ Records fault data, which is retained even during power loss.

◆ Standard RS232 serial communication; onboard RS232 port features optical isolation for convenient field maintenance.

◆ Supports LonWorks fieldbus/485 bus/single Ethernet/dual Ethernet communication interfaces.
