Core Product Characteristics
It adopts high-precision phase and frequency detection algorithm to achieve fast and stable generator synchronization and prevent out-of-phase closing. Dual parameter set function allows users to store two groups of breaker closing parameters for two separate circuit breakers. Front panel LCD display and LED indicators provide real-time status visualization for voltage, frequency and synchronizing status. Built-in synch-check interlock protection blocks breaker closing if phase or frequency deviation exceeds preset limits. It supports USB connection for parameter configuration, trend recording and fault event log download. The front panel mounting design fits standard control cabinet cutout for convenient installation and on-site replacement. It works reliably within ambient temperature from -20°C to +70°C, with relative humidity 5% to 95% non-condensing. It complies with CE EMC standards and meets power plant and marine power control requirements.
Application
This Woodward 8440-2173 synchronizer is widely used in generator paralleling control in power plants, industrial standby power systems, marine power stations and combined heat and power units, serving as spare parts for power system maintenance and retrofit.
