ABB SPTSA01 Rack Steam Turbine Automatic Synchronous Module

Product Description

SPTSA01 is a turbine auto-synchronization module for ABB Bailey Symphony Harmony Rack. It is a dedicated turbine control card for generator synchronization. It collects AC voltage signals, monitors voltage difference, frequency difference and phase angle difference, and executes closing capture logic for grid connection. It is rack plug-in and compatible with BRC controllers. This model is discontinued and supplied as spare part for legacy power plant turbine control, replaced by SPTAS01.
