Product list of Control Relays
Modern automation , control and remote control systems have become essential for optimised and secure control and monitoring of processes regarding power distribution and industrial networks . Depending on the specific field of application , different requirements have to be met by the devices .
The synchro-check device measures two voltages with regard to phase, frequency and voltage difference in order to interconnect grids which are under voltage . Various conditions can be defined for command output blocking . Beside application of SPRECON-E-C-SYNC as a stand-alone device, the synchro-check functionality can be also integrated into a SPRECON-E-C bay computer together with other control functions .
With frequency-based load shedding , consumers can be automatically disconnected from the power network on the occurence of frequency reduction . This function avoids network splitting as well as switching-off power plant units . Hence, the existing power network can be sustained .
SPRECON-E-C-SIG captures different process conditions via digital and/or analog signalling. The unit can be applied to: Electric power supply, Municipal utilities , Industries . Signals can be further processed with different functions: Contact debouncing , Chatter blocking , Signal filtering , Signal delay , Signal summation , Signal grouping , Logic operations . HMI control & alarm panel : Attached or detached mountable , 100 individual. config. LEDs (alarm panel) , Full-graphical colour display (high resolution) with 25 Beside application of SPRECON-E-C-SIG as a stand-alone device , the alarm indication functionality can be also integrated into a SPRECON-E-C bay computer together with other control functions .
Transformers with motor-driven tap changers can be controlled with automatic voltage regulators . Actuation of the motor drive leads to a voltage change by one tap. If the difference between actual voltage and set-point exceeds a certain limit, a regulation command (”up”, “down”) is initiated .
