Basler Electric SGC-250 Synchronous Generator Controller

Overview

The SGC-250 Synchronous Generator Controller is a prepackaged solution

for applications that require single or dual DECS-250 Digital Excitation Control

Systems. With the DECS-250’s enhanced capabilities, precise generator voltage

control can be obtained. An optional integrated BE1-11g Generator Protection

System provides generator current differential protection, monitoring, and

metering with multiple protection schemes to assist with generator protection.

Benefits

• The DECS-250 and optional BE1-11g used on the SGC-250 are

programmed using BESTlogic™Plus within BESTCOMSPlus

software. With its intuitive interface, BESTlogicPlus provides

the flexibility to create custom logic schemes to meet specific

requirements.

• An automatic tuning feature is integrated into the DECS-250

to reduce commissioning time and provide excellent system

performance.

• Real time monitoring and event recording capture occurrences

within the system for live data analysis.

• Prewired for easy installation into new or existing enclosures.

• Dual control power provides redundancy to prevent undesired

shutdown.

• Current transformer (CT) shorting provision for added safety.

• The SGC-250 is designed, built, and completely tested to optimize

performance and reliability
