Description
The tap-changing mechanism and current-carrying contacts are designed to provide exceptional reliability and long service life exceeding one million mechanical operations. The tap changer uses an electric motor, gear train, and spring drive to provide quick, reliable operation.
The RWT-20 Voltage Regulator Control front panel makes data collection and control quick and efficient. Use the front panel to analyze operating information, view and change device settings, and perform control functions. The RWT-20 features a straightforward menu-driven control structure presented on the front-panel liquid crystal display (LCD). Front-panel LED indicators provide a fast means of checking operation status. You can perform often-used control actions rapidly by using the large direct-action pushbuttons.
? Distribution Automation Ready. Interface with either on-the-flysettings changes over DNP, or master controller direct-operate interface.
? Flexible Communications. Easily interface with your network with the Industry's most network connectable regulator controller.
? Programmable Without a Laptop. Connect a USB flash drive to upload new settings, upgrade firmware, retrieve existing settings, or retrieve reports from the SEL-2431.
? Expandable, Removable Memory. Connect a USB flash drive and enable Automatic Backup to write all common reports to the USB forlong-term storage and easy retrieval.
? IEEE C37.118 Synchro phasor Protocol. Identify connected phase of downstream voltage regulators by coordinating with sychrophasor measurements in the substation.
